Question

which of the following is the phenotypic ratio obtained in a mendelian dihybrid cross​

Answer 1

Answer:

In this Dihybrid Cross, homozygous dominant traits were crossed with homozygous recessive traits. This particular cross always results in the phenotypic ratio of 1:0:0:0 meaning that the offspring will all have both dominant phenotypes but will be carriers of the recessive phenotypes.

Answer 2

Answer:

A dihybrid cross is a cross between F

1

offspring (first - generation offspring) of two individuals that differ in two traits of particular interest.

For example : RRyy / rrYY or RRYY/ rryy parents result in F

1

offspring that are heterozygous for both R and Y (RrYy)

Thus, Mendel's dihybrid ratio is depicted by: 9:3:3:1
