Question

The genotypes of a plant variety were TtHh, Tthh, ttHh and tthh, where T = tallness and H= hairy stem. Which one of the following crosses would produce progeny giving a phenotypic ratio approximately 1:1:1:1 ?

Answer 1

Explanation:

1:1:1:1

1 tall and hairy = T_H_

1 non tall and hairy = ttH_

1 tall and non hairy = T_hh

1 non tall and non hairy = tthh

this can only be produced from

TtHh x tthh crossing
