Assume that a dihybrid cross for two different traits (AaBb × AaBb) is made in which the gene loci are autosomal, independently assorting, and both incompletely dominant. What phenotypic ratio would you expect from such a cross?

Respuesta :

Answer:

Independent assortment is one of the very important rule that was given by Mendel.

Explanation:

Here the given dihybrid cross is between AaBb and AaBb.

They should be independently assorting and incompletely dominant

The phenotypic ratio obtained from such cross will be- 1:2:1:2:4:2:1:2:1. I have attached the cross in the word file. Please download and check the complete explanation. The dihybrid cross will help you to obtain the phenotypic ratio. This is the same phenotypic ratio observed from Mendel experiment of independent assortment.

The phenotypic ratio from such a cross would be ; 1 : 2 : 1 : 2 : 4 : 2 : 1 : 2 :1

According to Mendel's experiment and theory for a dihybrid cross each of the hybrids should be independently sorting and also incompletely dominant of one another.

The Phenotypic ratio obtained from the dihybrid cross is as follow

  AB           Ab           aB         ab

AB  AABB AABb AaBB AaBb

Ab  AABb AAbb AaBb Aabb

aB  AaBB AaBb aaBB aaBb

ab  AaBb Aabb AABb aabb

Hence we can conclude that The phenotypic ratio from such a cross would be ; 1 : 2 : 1 : 2 : 4 : 2 : 1 : 2 :1
