Question

In cats, the long hair trait is dominant and the short hair trait is recessive. What is the chance of a homozygous short-haired offspring if a heterozygous long-haired male mate with a short-haired?

Answer 1

Answer:

the chance of a homozygous short-haired offspring if a heterozygous long-haired male mate with a short-haired is 50%

Explanation:

The best way to see this is to simply draw a punnett square. As you've said, let's call  

S

the dominant trait (short hair) and  

s

the recessive trait (long hair):

As shown in the image i uploaded:

As you can see, out of the 4 possible outcomes, 2 will result in short hair, and 2 in long. So, you'd have a  chance of getting a short haired cat.

Answer 2

L = Long hair

l = short hair

                            L  l

                l          Ll   ll

                l          Ll   ll

I hope this helped :D

The chances of a heterozygous long haired offspring is 50%

The chances of a homozygous long haired offspring is 0%
