Question

In tomatoes, red fruit is dominant to yellow fruit and purple stems are dominant to green stems. The progeny from one mating produces 305 red fruit, purple stem plants, 328 red fruit green stem plants, 110 yellow fruit, purple stem plants and 97 yellow fruit, green stem plants. What are the genotypes of the parents? Albinism is a condition in which pigmentation is lacking. In humans the result is white hair, pink eyes and no skin pigmentation. The trait in humans is caused by a recessive allele. Two normal parents have an albino child. What are the genotypes of the parents and what is the probability their next child will have albinism?

Red fruit= R

Yellow fruit= r

Purple stem=P

Green stem=p

Red fruit purple stem= 305

Red fruit, green stem= 328

Yellow fruit purple stem =110

Yellow fruit green stem= 97

The genotypes of the parents:

RrPp (red fruit, purple stem) x Rrpp (red fruit green stem)

RRPp (Red fruit purple stem)

RrPp (Red fruit purple stem)

RRpp (Red fruit green stem)

Rrpp (Red fruit green stem)

RrPp (Red fruit purple stem)

rrPp (yellow fruit purple stem)

Rrpp (Red fruit green stem)

rrpp (yellow fruit green stem)

RRPp (Red fruit purple stem)

RrPp (Red fruit purple stem)

RRpp (Red fruit green stem)

Rrpp (Red fruit green stem)

RrPp (Red fruit purple stem)

rrPp (yellow fruit purple stem)

Rrpp (Red fruit green stem)

rrpp (yellow fruit green stem)
