Question

Two parents, both heterozygous (Tt) and tall, are crossed to produce offspring. What are the possible genotypes and phenotypes of the offspring? What is the percentage chance of being homozygous?

Answer 1

Look below

Step-by-step explanation:

The possible genotypes of the offspring are: TT, Tt, and tt.

The possible phenotypes of the offspring are: tall and short.

The percentage chance of being homozygous can be calculated using a Punnett square. When the heterozygous parents are crossed, the possible genotypes of the offspring are:

| T | t

--|---|---

T | TT| Tt

t | Tt| tt

From the Punnett square, we can see that there is a 25% chance of the offspring being homozygous (TT or tt). This is because there are four possible outcomes and two of them result in a homozygous genotype (TT and tt).
