Question

what will you get in f1 and f2 gene ross - tall violet ( TTWW) and short white ( ttww)​

Answer 1

Answer:

The appearance of the recessive trait in F

1

generation (dwarfism) confirms the presence of one recessive allele in the dominant parent and makes it heterozygous for plant height (Tt). Since all F

1

generation has a violet flower, the dominant parent is homozygous for flower color. If the dominant parent was double heterozygous (TtWw), the F

1

generation would exhibit recessive traits of both plant height and flower color. But all F

1

generation exhibits violet flowers which confirm that the dominant parent is homozygous for flower color.
