Question

There is a dog breeder that breeds black labs. Both the mother and father

dogs have black fur, but the breeder had a puppy once with yellow fur. She
was so surprised that she had their genes tested. What would be an
appropriate claim? *

1.The puppy gets one yellow coloring gene from his mom and one yellow coloring gene
from his dad.

2.The puppy gets one black coloring gene from his mom and one yellow coloring gene
from his dad.


3.The puppy gets one yellow coloring gene from his mom and one black coloring gene
from his dad.

Answer 1

I don't know if this will exactly answer your question, but we'll see.

Explanation: The puppy's parents both have at least one dominant allele in their genetics for black fur. One of them might have a recessive allele for yellow fur. Since there is a dominant allele for black fur, the yellow fur will not show up. The puppy probably has both recessive alleles for yellow fur. If there was one dominant allele, the puppy would be black.

I hope this helps :)
