In a cross,$75$ tall plants and $25$ dwarf plants are obtained. What would be the genotype of the parents?

In pea plants,yellow seeds are dominant to green. If a heterozygous yellow seeded plant is crossed with a green seeded plant,what ratio of yellow and green seeded plants would you expect in $F_1$ generation?

In the case of inheritance of one gene,the phenotypic ratio of $3:1$ can be explained on the basis of which of the following?

How many different types of gametes will be produced by a plant with the genotype $AABbCC$?

Using a Punnett square,work out the distribution of phenotypic features in the first filial generation after a cross between a homozygous female and a heterozygous male for a single locus.

In a monohybrid cross,if you get a $3:1$ ratio,it denotes that:
