## What is Timmy’s genotype?

What is Timmy’s genotype? Timmy is homozygous dominant (FF) for freckle trait.

## What is the probability of their daughter Maria having each of the possible phenotypes?

What is the likelihood of their daughter Maria having each of the possible phenotypes? Because there is a 25% chance that Maria will be homozygous dominant and a 50% chance that she will be heterozygous for trait R, there is a 75% chance that she will display the dominant phenotype, the ability to roll the tongue.

## What is the probability of having an offspring that is homozygous?

If two homozygous dominants are crossed, the probability that an offspring will be homozygous dominant is 100% or 1.00. 8. If two homozygous recessives are crossed, the probability that an offspring will be homozygous recessive is 100% or 1.00.

## Does Sally have freckles?

According to the Punnett square, Sally does have freckles because she has a dominate trait whichgives her a 50% chance of having freckles.

## What phenotype means?

The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. An organism’s phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.

## What is the mother’s phenotype?

The maternal genotype determines the phenotype of the offspring. Maternal effects often occur because the mother supplies a particular mRNA or protein to the oocyte, hence the maternal genome determines whether the molecule is functional.

## What is your phenotype and possible genotype S for cleft chin?

In the example of the cleft chin, where B is cleft chin (dominant allele), wherever a pair contains the dominant allele, B, you can expect a cleft chin phenotype. You can expect a smooth chin phenotype only when there are two copies of the recessive allele, bb. (b) A cleft chin, shown here, is an inherited trait.

## How much is the probability of a homozygous dominant genotype?

One Homozygous Parent

Above if the homozygous parent has two dominant alleles, then all of the offspring will have the same phenotype of the dominant trait. In other words, there is a 100% probability that an offspring of such a pairing will exhibit the dominant phenotype.

## What is the probability of a heterozygous offspring?

The possibilities are summarized: There is a 50% x 50% = 25% probability that both of the offspring’s alleles are dominant. There is a 50% x 50% = 25% probability that both of the offspring’s alleles are recessive. There is a 50% x 50% + 50% x 50% = 25% + 25% = 50% probability that the offspring is heterozygous.
