A test cross with an organism with a homozygous recessive genotype
results in 50% of the offspring exhibiting the recessive trait.
What is the genotype of the test-cross
parent?
I. Homozygous recessive
II. Homozygous dominant
III. Heterozygous
A. I only
B. II only
C. III only
D. I or III
E. II or III

Sagot :

The answer is heterozygous.

If it was crossed with homozygous dominant, then 100% of the offspring would show the dominiant trait. If it was homozygous recessive 100% of the offspring would have the recessive trait

I say C. III ONLY, because if you put this all out on a punnet chart that is the only one that comes out with a correct outcome, 50%, so I say it is heterozygous only, answer choice C!
