In a plant tallness is dominant over dwarfness and red flower is dominant over white.Starting with the parents work out a dihybrid cross.What is standard dihybrid ratio? Do you think the values would deviate if the two genes in question are interacting with each other?

In peas, tallnessis dominant over dwarfness, and red colour of flowers is dominant over the white . colour. When a'tall plant bearing red flowers was pollinated with- a dwarf planfc bearing white flowers, the different phenotypic groups were obtained in the progeny in numbers mentioned against them: Tall, Red = 138 Tall, White = 132'Dwarf, Red =136 Dwarf,White =128 Mention the genotypes of the two parents and of the four offspring types.

A pure tall plant with red flowers is crossed with a pure dwarf plant with white flowers. What will the dihybrid ratio be when the genes interact with each other?

Twogenes'A'and 'B'arelinked.In a dihybrid cross involving these two genes, the FI heterozygote is crossed with homozygous recessive parental type (aa bb).What would be the ratio of offspringin the next generation?
