The genotype of offspring formed from Tt x tt will be ________.
Open in App
Solution
The correct option is A Tt and tt
The heterozygous parent can produce two types of gametes one having T allele and other having t allele. However, second parent being homozygous can produce only one type of gamete having t allele. Random mixing of these gametes will produce following progeny:
Tt one half the total number of progeny.
tt one half the total number of progeny.
This cross is a typical Mendelian test cross.
