Answer
Correct option: B.
$Tt$ 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.
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.
