## What is the probability of an offspring being homozygous dominant?

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

## What are the predicted offspring of two homozygous dominant parents?

The offspring of two homozygous dominant parents has a 75% chance of exhibiting the dominant trait.

## What are the chances of having offspring that is heterozygous for both traits?

In another example (shown below), if the parent plants both have heterozygous (YG) genotypes, there will be 25% YY, 50% YG, and 25% GG offspring on average. These percentages are determined based on the fact that each of the 4 offspring boxes in a Punnett square is 25% (1 out of 4).

## Is homozygous dominant for both traits?

A homozygous genotype is one in which both alleles are the same, and an organism with a homozygous genotype is said to be true-breeding or purebred. A homozygous dominant genotype is one in which both alleles are dominant.

## What is the probability of the parents having a child who is homozygous dominant for this trait?

There is a 50% chance that the children will be heterozygous (Aa) and a 25% chance that they will be homozygous dominant (AA). Children with either of these genotypes will have this trait expressed in their phenotypes.

## What is the chance a homozygous dominant parent passes on a dominant allele?

The heterozygous parent would have a 50 percent chance of passing the dominant allele for this disorder to his or her offspring, and the homozygous parent would always pass the normal allele. Therefore, four possible offspring genotypes are equally likely to occur: Nn, Nn, nn, and nn.

## What is the chance a homozygous recessive parent passes on a dominant allele?

If both parents carry only one copy of a recessive gene, the likelihood of a child bearing the recessive trait is one in four. The probability rises to two in four if one parent is homozygous recessive for the gene — for example, ww — and the other parent is heterozygous.

## What is the chance of the offspring having heterozygous genotype in a cross between a homozygous dominant parent and a recessive parent?

Terms in this set (23)

In a cross between a homozygous dominant parent and a homozygous recessive parent, what is the chance of the offspring having a heterozygous genotype? The probability of inheriting either an A, B, or O allele for blood type from your parent is 33.33%.

## How does probability relate to the Punnett square and the offspring that are shown?

a punnett square takes two people with certain genotypes, and lists all the possible genotypes of their offspring. … the probability of a certain combination of alleles in the offspring is the number of times it appears in the punnett square divided by the total number of combinations in the punnett square.

## What is the probability that two heterozygous parents will produce a blue eyed child?

If both parents are heterozygous for eye color, the probability that a child will have blue eyes is 14 or 0.25 , for each child, because each birth is an independent event.

## What is the probability of homozygous recessive rr?

About one-fourth will be homozygous dominant for round seed shape (RR), half will be heterozygous for round seed shape (Rr), and one-fourth will have the homozygous recessive wrinkled seed shape (rr).

## Is homozygous dominant or recessive?

Homozygous means that the organism has two copies of the same allele for a gene. An organism can be homozygous dominant, if it carries two copies of the same dominant allele, or homozygous recessive, if it carries two copies of the same recessive allele.

## What are homozygous and heterozygous traits?

Homozygous: You inherit the same version of the gene from each parent, so you have two matching genes. Heterozygous: You inherit a different version of a gene from each parent. They do not match.
