As a result of the marriage between a curly-haired mother and a straight-haired father,$8$ children are born. What is the expected ratio of curly-haired to straight-haired children?

What will be the phenotypic ratio obtained from the selfing of a plant with the genotype $AABb$?

$A$ black dog heterozygous for the colour is crossed with a white bitch,which is recessive homozygous. The progeny will show black to white offspring in the ratio of:

$A$ cross between $AaBB$ and $aaBB$ produces which type of genotype?

$A$ true-breeding plant producing red flowers is crossed with a pure plant producing white flowers. The allele for the red color of the flower is dominant. After selfing the plants of the first filial $(F_1)$ generation,what would be the proportion of plants producing white flowers in the progeny?

$A$ test cross of an unknown yellow seed with a green seed produces $50\%$ green seeds and $50\%$ yellow seeds. What is the genotype of the unknown yellow seed?
