When heterozygous red flowered plant is crossed with white flowered plant, the progeny will show ratio of

Exposure of an organism to UV rays causes

Recessive mutation are expressed normally

A Mendelian experiment consisted of breeding tall pea plants bearing violet flowers with short pea plants bearing white flowers. The progeny all bore violet flowers, but almost half of them were short. This suggests that the genetic make-up of the tall parent can be depicted as

In rabbits, black (B) coat colour is dominant over white (b) coat colour. Which Punnett square correctly represents a cross between a rabbit heterozygous for coat colour and a white rabbit?

A student completed a genetics exercise by preparing this Punnett square. [Note: 'T' represents a dominant allele and 't' represents a recessive allele.]
What were the likely genotypes of the parents ?

Mating of an organism to a double recessive in order to determine whether it is homozygous or heterozygous for a character under consideration, is called as

The reason why some mutations, which are harmful, do not get eliminated from gene pool is that

Mutagenic effect of $$X$$-rays was discovered by Muller in

Which hexaploid wheat is used to make bread?
