Exam 5: Chromosomes and Inheritance

Albinism is a recessive disorder in which the skin and hair fail to produce pigment.The following question(s) ask you to evaluate the pedigree chart shown here in which "N" is the allele for normal pigmentation and "n" is the allele for albinism.The shaded circles for Deirdre and Shannon represent the only individuals expressing the disorder. -What is Bill's genotype?

What was the probability that Deirdre and Geoff's first child would express the albino trait?

Genes are located on ________.

What is cytokinesis?

Assuming complete dominance, what is the expected ratio of genotypes of the offspring following the cross of two heterozygotes?

Assuming incomplete dominance, if a homozygous red-flowered plant is crossed with a homozygous white-flowered plant, what will be the color of the offspring?
