What is the genotype of an individual?

A genotype is an individual’s collection of genes. The term also can refer to the two alleles inherited for a particular gene. … The expression of the genotype contributes to the individual’s observable traits called the phenotype.

What are the 3 types of genotypes?

There are three types of genotypes: homozygous dominant homozygous recessive and hetrozygous.

What is genotype AA?

The term “homozygous” is used to describe the pairs “AA” and “aa” because the alleles in the pair are the same i.e. both dominant or both recessive. In contrast the term “heterozygous” is used to describe the allelic pair “Aa”.

What is the relationship between individuals III-1 and III-2? III-1 and III-2 are brothers/siblings.
The pattern of inheritance shown in this pedigree is typical for what type of trait? The pattern is typical for a recessive trait.

What is the genotype of individual 5?

ANS: No the genotype of individual 5 is uncertain because his children have free earlobes. Thus individual 5 could be homozygous (FF) or heterozygous (Ff) for free earlobes. If however one of his children had attached earlobes it would be certain that individual 5 was heterozygous. 34.

What term can be used to describe individual II 3?

Recall that this pedigree shows the inheritance of a rare autosomal dominant condition. … Individuals III-3 and III-4 are expecting their first child when they become aware that they both have a family history of this recessive condition.

What are the heterozygous genotypes?

(HEH-teh-roh-ZY-gus JEE-noh-tipe) The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).

What is the genotype of the man what is the genotype of the man?

Male Genotype

When a sperm carrying the Y chromosome fertilizes an egg the resulting embryo has a genotype of XY and will be a male. With rare exceptions all other embryos will be XX or female. Although the Y chromosome codes for a male the X chromosome is vital for normal human development.

How do you find the genotype in a pedigree?

How do I find out my genotype?

If you prefer finding out your genotype with the help of a blood test you can visit the hospital nearby and the doctor will take the blood sample from your arm. When they have enough blood they take it for analysis to the laboratory. The laboratory test determines the level of hemoglobin in your blood.

What are 2 examples of genotypes?

Other examples of genotype include: Hair color. Height. Shoe size.

Genotype examples
  • A gene encodes eye color.
  • In this example the allele is either brown or blue with one inherited from the mother and the other inherited from the father.
  • The brown allele is dominant (B) and the blue allele is recessive (b).

What is the meaning of AA AS and SS genotype?

Blood genotype indicates of the type of protein (Haemoglobin) that is in the red blood cells. You could be Haemoglobin AA AS AC SS or SC based on what is inherited from your parents. Individuals with blood genotype SC and SS are said to have sickle cell disease while AS is known as sickle cell trait.

What is type of genotype?

Human blood type is determined by co-dominant alleles. … A description of the pair of alleles in our DNA is called the genotype. Since there are three different alleles there are a total of six different genotypes at the human ABO genetic locus. The different possible genotypes are AA AO BB BO AB and OO.

What is the term genotype?

In a broad sense the term “genotype” refers to the genetic makeup of an organism in other words it describes an organism’s complete set of genes. … Each pair of alleles represents the genotype of a specific gene.

What genotype is SC?

The hemoglobin (Hb) SC genotype is seen in persons who have inherited the gene for hemoglobin S from one parent and the gene for hemoglobin C from the other. Some people with this genotype develop Hb SC disease a variant of sickle cell disease.

What is the best genotype?

Health Tips
  • Types of Genotype. The genotypes in humans are AA AS AC SS. They refer to the hemoglobin gene constituents on the red blood cells. …
  • Compatible genotypes for marriage are: AA marries an AA. That’s the best compatible. …
  • Solution. The only thing that can change the genotype is the bone marrow transplant (BMT).

What genotype is BB?

An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example this genotype is written BB. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. In our example this genotype is written Bb.

Can O+ have a baby with O?

That means each child of these parents has a 1 in 8 chance to have a baby with an O- blood type. Each of their kids will also have a 3 in 8 chance of having A+ a 3 in 8 chance of being O+ and a 1 in 8 chance for being A-. An A+ parent and an O+ parent can definitely have an O- child.

Can an individual IV 2 be a carrier?

Name the two individuals that should be marked as carriers of hitchhiker’s thumb. Q. Is it possible for individual IV-2 to be a carrier? … Yes because her parents are carriers.

What is the genotype of RR?

The (RR) genotype is homozygous dominant and the (rr) genotype is homozygous recessive for seed shape. In the image above a monohybrid cross is performed between plants that are heterozygous for round seed shape. The predicted inheritance pattern of the offspring results in a 1:2:1 ratio of the genotype.

How do you write Y linked genotype?

Males with the trait will have the genotype XYR and males without the trait will have the genotype XYr (with the allele on the Y). The alleles are not dominant over one another so the R and r were just randomly assigned as a symbol to represent each allele.

What gave you the essential information to decide that II 3 and II 4 were heterozygous?

What gave you the essential information to decide that II-3 and II-4 were heterozygous? this is because they have 3 children who have the dominant trait and 2 children who have the recessive trait. parents are also brown-eyed.

What is illustrated Figure 14 7 quizlet?

What is illustrated in Figure 14-7? have some normal hemoglobin in their red blood cells.

What does the Y chromosome carry?

The Y chromosome contains a “male-determining gene ” the SRY gene that causes testes to form in the embryo and results in development of external and internal male genitalia. If there is a mutation in the SRY gene the embryo will develop female genitalia despite having XY chromosomes.

Do pedigrees show genotype or phenotype?

Pedigrees represent family members and relationships using standardized symbols. By analyzing a pedigree we can determine genotypes identify phenotypes and predict how a trait will be passed on in the future.

What is genotype for a recessive trait found on the female chromosome?

The genotype for a recessive trait found on the female is XH.

What is the probability that III 3 is a carrier RR )?

Thus only 3 possible outcomes remain. From these 3 outcomes two would give a heterozygous genotype to III-3. Therefore the overall probability that III-3 is a carrier is 2/3 or 66.67%.

What is a heterozygous genotype example?

Together these alleles are called a genotype. If the two versions are different you have a heterozygous genotype for that gene. For example being heterozygous for hair color could mean you have one allele for red hair and one allele for brown hair.

Is II heterozygous or homozygous?

What is the genotype of the heterozygous offspring?


Heterozygous refers to having inherited different forms of a particular gene from each parent. A heterozygous genotype stands in contrast to a homozygous genotype where an individual inherits identical forms of a particular gene from each parent.

What are the genotypes of the woman and the man?

In humans the section of the genotype that represents female sex is XX and XY for males.
