Single Allele Traits

My 5 practice problems

My Creature

The creatures Arm is one single allele trait. It can be Curly (Dominant) or straight (Recessive)

Genotypes for each: Curly CC, Cc

Straight cc

Another one of the creatures single allele traits is if it has hands (mittens) or not

Has Hands (Dominant) or Does not have hands (Recessive)

Genotypes for each: Hands HH, Hh

No Hands hh

1. If a female box with curved arms (CC) mates with a male box with straight arms (cc), what is the probability that the offspring will have curved arms?

2. If a female box colored gray (Bb) mates with a male brown box (BB) how many offspring out of 4 will be colored brown?

3. If a female box with green eyes (xb xb) mates with a male box with green eyes (Xn y) what is the probability that the offspring will have blue eyes?

4.If a female box without hands (hh) mates with a male box with hands (Hh) how many offspring out of 6 will not have hands? Explain your answer.
