Hint: Dihybrid cross is defined as a cross between two different genes. One of the genes is considered as dominant while the other one is recessive. Here, Y is dominant over y and W is dominant over w.
Complete answer:
Option A-
yyWw- yellow smooth
yyWW- yellow smooth
yyww- yellow wrinkled
Option B – this cross is between green- wrinkled seed and green- smooth pea seed.
YyWw- green wrinkled
YYWW- green smooth
YYWw- green smooth
YYWw- green smooth
So, the cross shows that the result which is obtained is green and smooth peas. He first worked to obtain a monohybrid cross which has genotypic ratio 3:1 and the phenotypic ratio is 1:2:1. After receiving the successful result with his experiment, he went further to cross two different genes together with the genotypic ratio very long and phenotypic ratio 9:3:3:1.
Option C
yyWW- yellow smooth
Option D-
Yyww- green wrinkled
yyww- yellow wrinkled
Note:
The three laws of inheritance are-
1. Law of dominance- One gene is dominant over the recessive gene.
2. Law of segregation – Alleles do not show any blending and both the characters are found as such in the second generation.
3. Law of independent assortment- It says when two pairs of traits are taken together, segregation of the characters is independent of the other pair of characters.
