Question

A farmer mates a homozygous tall, red tomato plant (TTRR) with a heterozygous tall, red tomato plant (TtRr). Find the genotypes and phenotypes ratio

Answer 1

Cross between the two will produce following offspring -

TTRR - homozygous tall, red tomato plant

TTRr - Tall and red

TtRR - Tall and reds

TrRr -Heterozygote Tall and red

Step-by-step explanation:

Given -

Genotype of homozygous tall, red tomato plant is TTRR

Genotype of heterozygous tall, red tomato plant is TtRr

Gametes of TTRR - TR, TR, TR, TR

Gametes of TtRr - TR, Tr, tR, tr

Cross between the two will produce following offspring -

TTRR - homozygous tall, red tomato plant

TTRr - Tall and red

TtRR - Tall and reds

TrRr -Heterozygous Tall and red
