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?
Hello Heliodors! (cont.) Trait C The shape of a heliodor is an X-linked trait. Male heliodors inherit two X chromosomes, while the females inherit an X and a Y chromosome. The recessive allele codes for the common bell-shape while the dominant phenotype is a round shape U. Hudson is a round male and has offspring with Heidi, a bell-shaped female. They already have one daughter, Hannah, who is shaped like her mother. The reason for your answer above is: O Being male or female has no impact on the shape of a heliodor Males heliodors inherit two X chromosomes, so it is less likely they would only inherit two recessive alleles for being round. Females heliodors inherit two X chromosomes, so it is less likely they would only inherit two recessive allele for being round O Males only need to inherit one recessive allele to be round.

(i) Determine whether the husband is the biological father of the baby. Explain your answer in (i) above. (ii) 2. Silky feathers in fowls are caused by an allele which is recessive to the allele for normal feathers. 200 birds were raised from a cross between two heterozygous individuals. Predict the number of the birds that would expected to be silky and those expected to be normal. If about half of the offspring turned out to be silky, comment on the nature of the normal. If you had normal feather birds, propose the easiest way to determine whether its homozygous or heterozygous. 3. In dogs, black fur is dominant to white fur.
