You asked: What is the possibility of getting homozygous offspring?

What produces homozygous offspring?

One allele for every gene in an organism is inherited from each of that organism’s parents. In some cases, both parents provide the same allele of a given gene, and the offspring is referred to as homozygous (“homo” meaning “same”) for that allele.

What is the probability of a heterozygous child?

The chance of either parent being a heterozygote is 1/4, as calculated above. Then, the probability that both parents are heterozygotes, and the probability that two heterozygotes will have a heterozygous child, is 1/4 x 1/4 x 1/2 = 1/32.

How do you produce heterozygous offspring?

A cross between two different true-breeding individuals will produce heterozygous offspring. In genetics, the suffix “-zygous” refers to the allele pair an organism has for any given gene.

Can heterozygous be dominant?

If the alleles are heterozygous dominant, the faulty allele would be dominant. In such a case, the person may or may not be affected (compared to homozygous dominance where the person would be affected).

What is the difference between homozygous and heterozygous?

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.

What is an example of homozygous?

Homozygous examples

You can have brown eyes whether you’re homozygous (two alleles for brown eyes) or heterozygous (one for brown and one for blue). This is unlike the allele for blue eyes, which is recessive. You need two identical blue eye alleles in order to have blue eyes.

What is the probability of having a heterozygous kids when two heterozygous parents have kids?

The chance of either parent being a heterozygote is 1/4, as calculated above. Then, the probability that both parents are heterozygotes, and the probability that two heterozygotes will have a heterozygous child, is 1/4 x 1/4 x 1/2 = 1/32.

Can two albino parents have a normal child?

Not necessarily. There are different types of albinism that affect several different genes. If two people with the same type of albinism reproduce, all of their children will have albinism. If two people with two different types of albinism have children, NONE of their children will have albinism.
