The genotype of polydactyl father and normal mother whose child is normal. Introduction: According to Mendelian inheritance , a single character is controlled by one or more pairs of alleles. These alleles can be either dominant or recessive. Usually, dominant allele masks the expression of recessive allele. Recessive allele is expressed only in homozygous condition but dominant allele is expressed both in homozygous and heterozygous condition.

Question

Features of a Concept Features of a Concept Characteristics are discrete; that is, they are unitary. Genetic features have alternative forms, and each feature is inherited from one of the two parents. These are called alleles. One allele is dominant over the other allele. The dominant allele is reflected in the phenotype. Random segregation creates the gametes. The heterozygotic individuals produce gametes with an equal frequency of both alleles. Genes are unlinked; that is, different traits arise from the independent assortment.

In humans, the allele for normal blood clotting (H) is dominant to the allele for hemophilia. This is a sex-linked trait found on the X chromosome. A woman with normal blood clotting has four children: a normal son, a hemophiliac son, and two normal daughters. The father has normal blood clotting. What is the probable genotype for each member of the family?
