For green coloured pod and rounded seed, which is the functional unit of inheritance?

A brown-eyed couple has a blue-eyed child. The trait of brown eye$(2)$ is dominant over that of blue-eyed $(2)$. What is the genotype of the couple?

An allele is said to be dominant if

Which statement about alleles is not true?

When a gene exists in more than one form, the different forms are called as

In pea plants, the long-stem trait $(L)$ is dominant and the short-stern trait $(I)$ is recessive. Two pea plants were crossed, producing seeds that yielded 165 long-stem plants and 54 short-stem plants. The genotypes of the parent plants were most likely

An organism with two identical alleles of a gene in a cell is called

If a heterozygous tall pea plant is self-pollinated, what will be the heterozygous: homozygous proportion of the progenies?

How many genotypes are possible from a cross between the parent $RR$ and $rr$?

A tall plant was grown in nutrient deficient soil and remained dwarf. When it is crossed with dwarf plant then
