phenotypIn sheep, white wool (W) is dominant over black wool (w). What genotype and e ratios are expected from a cross between a heterozygous sheep with white wool and a sheep with black wool?

Respuesta :

A heterozygous white sheep means it has one of each trait (Ww).

A sheep with black wool is assumed to be homozygous because black wool is recessive (ww).

You can create a punnet square for Ww x ww.


W w
—————————-
w | Ww | ww |
|————+————-|
w | Ww | ww |
