A black rooster mates with a white hen. Based on their genotypes, the chance that the offspring will be checkered is 100 percent. What is the rooster’s genotype? What is the hen’s genotype? options for rooster- BB, Bb, bb, BW
options for hen- WW, Ww, ww, BW

Thank you!

Rooster - BB

Hen - WW

Explanation:

In some chickens, the gene for feather color is controlled by codominance, which means that the phenotype of the chicks is a combination of the parents' phenotype. If one parent is black, and the other is white, the chicks will be checkered.

The genotype for checkered chickens is BW. In order for all of the chicks to be checkered (BW), the black rooster's genotype has to be BB, and the white hen's WW. This is what the Punnett square would look like in this case:

     W      W

B   BW   BW

B   BW   BW

since there are no options posted i'll give you a few examples.

a dolphin's flipper, bird's wing, cat's leg.

examples of nucleic acids are deoxyribonucleic acid (dna) and ribonucleic acid (rna).
