In tomatoes, red fruit color is dominant to yellow. round-shaped fruit is dominant to pear-shaped fruit. tall

vine is dominant to short vine



A) if you cross a pure breeding tall plant bearing red, round fruit, with a pure breeding dwarf plant bearing yellow, pear shaped fruit, predict the phenotype of the f1 generation





B)Assuming that the genes controlling the 3 traits are on three different pairs of chromosomes, what are the possible genotypes in the f2 generation



C) what are the expected ratios of the phenotypes?



Can u explain to me the first part of the ? at least.

Thanks in advance; it would be realluy helpful :)

1- the phenotype will be red-round tall



explanation:

R=red T=tall P=round r=yellow t=dwarf p=pear shaped



you have this 2 plants:



a) RRTTPP

b) rrttpp



so, when you cross them in a *Punnett* square, you got



RrTtPp, and because all the progeny in the F1 has the same genotype, they are heterozygous, and are red-tall-round.



B) (see the link)

possible genotypes:

RRTTPP

RRTTPp

RRTtPP

RRTtPp

RRTtpp

RRttPP

RRttPp
