Title: If a tomato plant that is heterozygous for height and fruit colour is crossed...
Post by: Krystalniessen on Mar 31, 2016
In a hypothetical situation involving tomato plants red (R) is dominant over yellow (r) fruit. Located on a separate chromosome the gene for tallness (T) is dominant over dwarf (t) plants.

If a tomato plant that is heterozygous for height and fruit colour is crossed with a tomato plant that is recessive for both traits, the four possible genotypes are:

A. TtRr, TTRr, ttRr, ttrr
B. TtRr, Ttrr, ttRr, ttrr
C. TtRr, TtRR, ttRr, ttrr
D. TtRr, Ttrr, ttRR, ttrr
