In chickens, Black feathers (B) are dominant over white feathers (b). Complete the Punnett Square for the following cross:
Mother: BB
Father: bb
What percentage of offspring will be Black?
What percentage of offspring will be White?

(attached Punnett square below)

100% of the offspring will have black feathers

0% of the offspring will have white feathers

Explanation:

All the possible offspring have the genotype Bb, and since B (black) is dominant it will be the phenotype regardless of the presence of a b allele.

Therefore, all the offspring will be black (100%) and since none of the genotypes are bb there's no chance for white feathered chickens (0%)

hope this helps!

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.
