Question

Based on the punnet square above, what is the probability that an offspring from this cross will have a homozygous recessive genotype ?

A. 100%
B. 50%
C. 25%
D. 0%

Answer 1

25%

Step-by-step explanation:

Homozygous Recessive: (homo means same) Both letters representing the genes are the same, and they are recessive (lowercase t)

Each box within a punnett square represents a 25% chance possible outcome.

There is only one box in this punnett square wherein both letters are lowercase t.

Answer 2

C)25%

Step-by-step explanation:

the results of the punnet square are:

1. TT (homozygous dom)

2. Tt (heterozygous)

3. Tt (heterozygous)

4. tt (homozygous recessive)

capital letters are dominant and lowercase are recessive
