What is the cross between the progeny of $\mathrm{F}_{1}$ and the homozygous recessive parent called? How is it useful?
When a progeny of $\mathrm{F}_{1}$ is crossed with the homozygous recessive parent, it is called Test cross. Thiscrossis helpfulin determining the genotype of an unknownprogeny i.e., whether it is heterozy-gous or homozygous dominant for the trait.
Which of the following is genotypic ratio of Mendel's monohybrid cross
Mendel's contribution for genetic inheritance was
Chromosomal number in a cell of a flowering plant is
To determine heterozygousity of a cross, one has to perform
In a monohybrid cross, If you get $3:1$ ratio, it denotes that
