Analysis of X-Linked Dominant and Recessive Traits In the eighteenth century, a young boy with a skin condition known as ichthyosis hystrix gravior was identified. The phenotype of this disorder includes thickening of skin and the formation of loose spines that are sloughed off periodically. This man married and had six sons, all of whom had the same condition. He also had several daughters, all of whom were unaffected. In all succeeding generations, the condition was passed on from father to son. What can you theorize about the location of the gene that causes ichthyosis hystrix gravior?
Variations on a Theme by Mendel Pea plants usually have white or red flowers. A strange pea-plant variant is found that has pink flowers. A selfcross of this plant yields the following phenotypes: 30 red flowers 62 pink flowers 33 white flowers What are the genotypes of the parents? What is the genotype of the progeny with red flowers?
Can a male be a carrier of red-green color blindness?
Whyte type canaries are yelllow. A dominant mutant allel of the color gene, designated W causes white feathers. Inheriting two dominant alleles is lethal to the embryo. If a yellow canary is crossed to a white canary, what is the probability that an offspring will be yellow? What is the probability that it will be white? [ autosomal special condition]

Males with the recessive (hemophilia) allele, are affected. Females can be carriers.

Could the pedigree in Figure 2-31 be explained as an autosomal dominant disorder? Explain.
The maternal-effect mutation bicoid (bcd) is recessive. Inthe absence of the bicoid protein product, embryogenesis isnot completed. Consider a cross between a female heterozygousfor the bicoid mutation (bcd+/ bcd-) and a homozygousmale(bcd-/ bcd-). How is it possible for a male homozygous for the mutationto exist?
Night blindness is an X-linked dominant disorder. An individual who has the genotype XNX" for night blindness is a genetic carrier homozygous dominant female with night blindness female with normal vision
The maternal-effect mutation bicoid (bcd) is recessive. Inthe absence of the bicoid protein product, embryogenesis isnot completed. Consider a cross between a female heterozygousfor the bicoid mutation (bcd+/ bcd-) and a homozygousmale(bcd-/ bcd-). Predict the outcome (normal vs. failed embryogenesis) inthe F1 and F2 generations of the cross described.

The mode of inheritance of the auricular hypertrichous trait in the Brown family is clearly an instance of: Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. b d recessive inheritance with the females being carriers. dominant inheritance with the males being carriers. X-linked inheritance, which is being expressed in the males since they only have one X chromosome. Y-linked inheritance, which can never be passed on to females.
