- In rats, the following genotypes of two independently assorting autosomal genes determine coat color: A_B_ (gray); A_bb (yellow); aaB_ (black); aabb (cream). A third gene pair on a separate autosome determines whether or not any color will be produced. The CC and Cc genotypes allow color according to the expression of the A and B alleles. However, the cc genotype results in albino rats regardless of the A and Balleles present. Determine the F1 phenotypic ratio of the following crosses: (a) AAbbCC x aaBBcc; (b) AAbbCC x aaBBcc; (c) AABBCC x AABbcc.arrow_forwardThe gene for polydactyly (P) is autosomal and dominant to normal fingers (p). Hemophilia is sex-linked and recessive (X h ). A man and his wife both of whom are polydactylous and have normal red blood cells have a child who is non-polydactylous and with hemophilia. What are their genotypes?arrow_forwardWhat is polygenic inheritance? Discuss the issues that make polygenicinheritance difficult to study.arrow_forward

- The following pedigree illustrates the inheritance of ringed hair, a condition in which each hair is differentiated into light and dark zones. What mode or modes of inheritance are possible for the ringed-hair trait in this family?arrow_forwardExplain the central dogma of inheritance. Cite a specific example.arrow_forwardIn alley cats, the coat color is determined by a gene carried on the X-chromosome. At the same time, the alleles are expressed as intermediate (incomplete-dominance) inheritance. Genotypes and color are as follows: Females: X ^ b * X ^ b =yellow X^ B X ^ b = calico X ^ B * X ^ B =black Males: X ^ y * Y =yellow X ^ B * Y=bhck (a) A black cat has a litter of seven kittens: three black males, one black female and three calico females. Comment on the probable paternity of this litter and explain.arrow_forward
