There are 127 offspring from a cross of AaBb x AaBb. If Mendelian ratios are followed, how many offspring would you expect to have recessive phenotypes for both traits?

eight (8)

Explanation:

A phenotypic ratio of 9:3:3:1 is predicted from a cross of AaBb x AaBb (i.e., in a dihybrid cross). In this case, the expected phenotypic ratio is equal to:

A_B_ (9:3:3:1) =71.43 >> 71 both dominant phenotypes

aaB_ (9:3:3:1) = 23.81 >> 24 one dominant phenotype

A_bb (9:3:3:1) = 23.81 >> 24 one dominant phenotype

aabb (9:3:3:1) = 7.93 >> 8 both recessive phenotypes

Expected phenotipic ratio (9:3:3:1) = 71 + 24 + 24 + 8 = 127

"it built up in the atmosphere"

i think thats it, idk, i tried looking for this exact q& a for grad. and idk if i got this question right or sorry if im wrong

the answer to the blank provided is “an autosomal gene that is required for the expression of genes on the x chromosome”.

testis-determining factor, abbreviated as td, which is more popularly known as sex-determining region y or sry protein, is a dna-binding protein or  gene-regulatory protein/transcription factor, encoded by the  sry gene. it is the gene responsible for the initiation of male gender determination in humans.
