In a plant, red fruit (R) is dominant over yellow fruit (r) and tallness (T) is dominant over shortness (t). If a plant with RRTt genotype is crossed with a plant that is rrtt,
Options:
Answer:
C
Solution:
The genotype of parents is RRTt and rrtt. Hence, colour of the fruits will be red for all the progeny because one of the parents is homozygous dominant. With respect to plant height, the cross can correspond to a monohybrid test cross, and the result for such a cross will be tall: dwarf :: 1:1. The result of the above cross will be tall plant with red fruit: dwarf plant with red fruit :: 1:1
