Vedclass · Answer

(A) dihybrid cross involves two pairs of contrasting characters.In a dihybrid test cross,the $F_{1}$ hybrid (heterozygous for two traits) is crossed with a double recessive parent.The resulting phenotypic ratio of $1: 1: 1: 1$ indicates that the $F_{1}$ hybrid produces four different types of gametes in equal proportions.This occurs because the two pairs of alleles segregate and assort independently during meiosis,according to Mendel's Law of Independent Assortment.

The dihybrid test cross ratio of $1: 1: 1: 1$ proves that

In Mendel's dihybrid cross,what is the probability of obtaining a plant that is heterozygous for both traits (in $/16$)?

In Mendel's experiment with garden peas,round seeds $(RR)$ were dominant over wrinkled seeds $(rr)$. Yellow cotyledons $(YY)$ were dominant over green cotyledons $(yy)$. What will be the phenotypic ratio of the $F_2$ generation produced by crossing $RRYY \times rryy$?

Explain the Law of Independent Assortment based on a dihybrid cross.

If a plant having yellow and round seeds was crossed with another plant having green and wrinkled seeds,then the $F_{1}$-progeny are in the ratio:

During a dihybrid cross, in the $F_2$ generation, the ratio of individuals showing one dominant and the other recessive character will be . . . . . . of the total population. (in $/16$)
