3. Construct a pedigree chart by following the information given below. A man who is heterozygous for an autosomal dominant trait marries a woman who is unaffected by that trait. Suppose they have 5 children in this order: affected son, unaffected son, affected daughter, unaffected son and unaffected daughter. The youngest daughter married a man who does not carry the gene for the trait. They have 2 children, one boy and one girl. The eldest child of the generation I couple, on the other hand, married a woman who also exhibits the trait. They have 3 children, 2 girls and 1 boy, all of whom show the trait. genotypes of all persons in this pedigree chart? What are the

In individuals affected by cystic fibrosis, salt crystals may appear afterperspiration dries up. In addition, the disease causes respiratory disorderswhich can be both debilitating and lethal. It occurs in individuals homozygousfor recessive gene.

6. The pedigree below traces the inheritance of a particular disorder. Circles are females, squares are males. Shaded symbols are affected with the disorder (NOTE: "half-shaded" symbols are NOT used here, for heterozygous individuals).

6. A person is simultaneously heterozygous for two autosomal genetic traits. One is a recessive condition foralbinism (alleles A and a); this albinism gene is foundnear the centromere on the long arm of an acrocentricautosome. The other trait is the dominantly inheritedHuntington disease (alleles HD and HD+). TheHuntington gene is located near the telomere of oneof the arms of a metacentric autosome. Draw all copies of the two relevant chromosomes in this person asthey would appear during metaphase of (a) mitosis,(b) meiosis I, and (c) meiosis II. In each figure, labelthe location on every chromatid of the alleles forthese two genes, assuming that no recombinationtakes place.

Albinism is a recessive autosomal trait for skin pigmentation. Hemophilia is a sex-linked recessivedisorder of the blood. assign alleles to the traitsA – normal skin pigmentation X H – normal blooda – albino X h - hemophilia A double heterozygous woman marries a non-hemophilic man and heterozygous for skinpigmentation.  Double heterozygous means heterozygous for both traits. Aa for skin pigmentation andX H X h for blood trait. Therefore, the genotype of the woman is AaX H X h .  Non-hemophilic man is X H Y and heterozygous for skin pigmentation is Aa. The genotype,therefore, of the man is AaX H Y. What is the probability that they will have:a. a child with normal skin? _____________________b. a child with normal blood? _____________________c. an albino girl? _____________________d.

1. Hair or fur length in cats is controlled by a single, autosomal gene; the short hair-allele is dominant to the allele for long hair. Hair color is produced by a different gene which is located on the X chromosome. One allele for this sex-linked gene produces yellow, while an alternate allele produces black fur color; individualswhich are heterozygous for these alleles are calico or tortiseshell in color.If a long-haired, black male is mated with a calico female homozygous for short hair what kind of kittens will be produced in the Ej generation? Give both genotypes and phenotypes; express the genotypes bothsymbolically and in words. Label answers clearly!!
