Write do.wn the results of the given cross-`Tt & Tt`, TT & Tt, Tt & tt. Analyze the genotype of the parents of a colour blind friend.

Tt xx tt is

Choose the odd one and write it: TT,Tt, tt, XY

Tallness (T-) is dominant over dwarfness (tt) while red flower colour (R-) is dominant over white colour (rr). A plant with genotype TtRr is crossed with plant of genotype ttrr. Percentage of progeny having tall plants with red flower is

when a pure strain of tall plants (TT) within round seeds (RR) is crossed with a pure strain of short plants (tt) with wrinkled seeds (rr) , an F, generation is produced . The aelles for short and wrinkled are recessive to thiose for tall and round , respectively. When these F1 plants self pollinate ,what proportion of the F2 generation is short with wrinkled seeds?

Tt mates with tt. What will be characteristic of offsprings?

Heterozygous tall (Tt) is crossed with homozygous tall (TT). Percentage of heterozygous tall in the progeny would be

The pea plants produced from the sseeds obtained from a cross between hybrid tall (Tt) and pure dwarf (tt) pea plants will be
