Vedclass · Answer

(A) To find the phenotypic ratio of the cross $Aabb 	imes Ccdd$,we analyze the inheritance of each gene pair independently.$1$. For the first gene pair: $Aa 	imes Cc$ (assuming independent assortment of alleles,though these are different genes,we treat them as independent traits).$2$. Actually,the cross is between two individuals with genotypes $Aabb$ and $Ccdd$.$3$. The cross can be broken down into two independent monohybrid crosses:- Cross $1$: $Aa 	imes Cc$ (This is not a standard cross,but if we assume independent segregation of alleles $A/a$ and $C/c$):- The offspring for $Aa 	imes Cc$ would be $1 AC : 1 Ac : 1 aC : 1 ac$.- Cross $2$: $bb 	imes dd$ (This results in $100\%$ $bd$ phenotype).$4$. Combining these,the phenotypic ratio is $1 : 1 : 1 : 1$.

What will be the phenotypic ratio of the offspring obtained from a cross between $Aabb$ and $Ccdd$?
