The parents are brown-eyed, rhesus-positive, with II group of 

blood. They are heterozygotic by all three traits. How many and 

what types of gametes form of this parents? Brown eyes is 

autosomal.

Four main differences between the meiotic and mitotic cell division.

All gametes of the male contain a dominant allele, while all gametes of the female contain a recessive allele (P generation). Determine the genotypes and phenotypes (dominant / recessive trait) of the parental generation, possible genotypes and phenotypes of the F1 and F2 generations.

The man's mother is colorblind and the woman's father is colorblind. a. Determine the genotypes of men and women. b. Identify the possibilities of giving birth to their children (given color blindness).

Polydactyly (increased number of fingers) in humans is determined by the dominant allele P. In the marriage of a six-fingered woman and a normal man, two six-fingered and one normal five-fingered child were born. Determine the genotypes of the parents.
