Question

alf ho or 1 There are two alleles for hoof color in centaurs (diploid organisms). Hector is homozygous recessive and he has purple hooves. Athena is homozygous dominant and she has pink hooves. Their son mates with a female centaur who has purple hooves and they have a litter of 166 baby centaurs. 4) Draw two Punnett squares: (1) for Hector and Athena, and (2) for their son and his mate. 5) How many (quantity, not percentage) of Hector and Athena's grandchildren would we expect to have purple hooves? (Show all work for full credi.)

Explanation / Answer

Hector - Male -            Homozygous Recessive (Purple)    aa

Athena - Female -       Homozygous Dominant (Pink)         AA

Hector and Anthena - All are Pink

Son Aa (Pink) and   Female centaur aa (Purple)

5. For purple hooves of hector and athena grandchildren is 83.

Son Aa (Pink) and   Female centaur aa (Purple) gives the 1:1 ratio of Purple vs pink.

So, 166/2 = 83 are pink and other 83 purple

A   Anthena A Anthena a Hector Aa    Pink Aa   Pink a Hector Aa   Pink Aa   Pink
