In one type of dog, black spots (b) are dominant over brown spots (b) and long tails (l) are dominant over short tails (l). use the dihybrid cross for parents with the genotypes bbll and bbll and determine the likelihood of offspring with the phenotype of brown spots and short tails.

Option A, 0%

Explanation:

It is given that

a) black spots (B) are dominant over brown spots (b)

b) long tails (L) are dominant over short tails (l)

Thus, the offspring with genotype "bb" will be of brown color as b is a recessive trait.

Also, offspring with genotype "ll" will have short tail as short tail is a recessive trait.

Thus, in the given punnet square genotype representing brown color and short tail together are - zero

Thus, option A is correct.

this website is for anybody really not just for girls just saying, also while a lot of males are mean and you know there are the few who are kind and then there's the nice-guys but then theirs also guys like me who are shy we don't get out much because there are people like you who exist who would most likely punch a guy in the face so next time just think about things before you post them to a website where guys and girls can see your question.
