Coloring genes for cat hair are located on the X chromosome. Black coloration is determined by the red XB gene, Xb, heterozygotes are tortoiseshell. From a black cat and a ginger cat, one tortoise and one black kitten were born. Determine the genotypes of parents and offspring, the possible gender of kittens.
1) the genotype of a black cat XB XB,
2) the genotype of a red cat – Xb Y,
3) genotypes of kittens: tortoiseshell – ХB Хb, Black – ХV Y,
gender of kittens: tortie – female, black – male.
