Analyze the pedigree. Determine the type of inheritance of a character and give the genotypes of persons 1, 2, 3, 4 in the pedigree.

Albinism in rye (i.e. cereal(s) is inherited as autosome recessive sign. At the examined plot there were found 210 albino plants among 84000 plants. Determine the frequency of albino gene in rye.

In a family, where both parents have normal vision, there was born a son with daltonism and two daugh-ters with normal vision. The first son has a son with normal vision. The children of the first daughter are a son with daltonism and a daughter with normal sight. The second daughter has five healthy sons. Draw the pedigree of the family. Determine the probability of birth of the healthy sons in a family of first daughter.
