| What will be the offspring in f1 from crossing a tomato if the mother plant is heterozygous round and the father is pear-shaped?
Since the heterozygous plant has a round fruit, the gene for the round shape of tomatoes should be adopted as dominant. Let’s designate it as C. Then the gene that causes the pear-shaped fruit of tomatoes will be designated as S.
Heterozygous tomato Cc produces two types of germ cells – C and c.
A tomato with a pear-shaped fruit will be homozygote for the recessive gene – cc. It will produce the same type of sex cells with.
F1 offspring from crossing these plants will be represented by the options:
heterozygote tomatoes with a round fruit (Cc) – 50%;
homozygous tomatoes with pear-shaped fruit (cc) – 50%.
