$A$ man homozygous for brown eye colour marries a lady heterozygous for brown eye colour. Brown eye colour is dominant over blue. What will be the phenotype of their children?

In humans,blue eye color is recessive to brown eye color. If a blue-eyed woman marries a brown-eyed man whose mother had blue eyes,what will be the expected eye color of their children?

$BB =$ alleles for black coat colour
$bb =$ alleles for brown coat colour
If the offspring of a cross between a black mouse $(BB)$ and a brown mouse $(bb)$ are allowed to interbreed,find the percentage of black-coated mice in the $F_2$ generation.

$A$ tobacco plant which is heterozygous for albinism ($a$ recessive character) is self-pollinated. If $1200$ seeds are subsequently germinated,how many of the seedlings would have the parental genotype?

$A$ tall true-breeding garden pea plant is crossed with a dwarf true-breeding garden pea plant. When the $F_1$ plants were selfed,the resulting genotypes were in the ratio of:

In one of the hybridisation experiments,a homozygous dominant parent and a homozygous recessive parent are crossed for a trait. (Plant shows Mendelian inheritance pattern)
