The important and universal phenomenon of life, "$Like\, begets\, like$", is due to .....

Statement-$I$: The segregation of alleles is a random process and so there is a $50\%$ chance of a gamete containing either allele.
Statement-$II$: Alleles do not show any blending at either $F_1$ or $F_2$ generation.

Mendel's findings were first published in the journal titled:

Fruit flies $(Drosophila \text{ } melanogaster)$ are one of the best materials for genetic studies because of all, except:

Which of the following crosses will result in recessive progeny in the $F_1$ generation?

Genotype of $F_1$ individuals can be tested by
