The gene controlling ABO blood type and the gene underlying nail-patella syndrome are said to show linkage. What does that mean in terms of their relative locations in the genome? What does it mean in terms of how the two traits are inherited with respect to each other?
What evidence indicates that a trait is coded by a dominant allele on an autosome?
In humans, brown eyes (B) are dominant over blue. A brown eyed man marries a blue-eyed (b) woman and they have three children two of whom are brown-eyed and one of whom is blue-eyed. what are the possible genotypes of the children?
In humans, brown eyes (B) are dominant over blue. A brown eyed man marries a blue-eyed (b) woman and they have three children two of whom are brown-eyed and one of whom is blue-eyed. if the male has brown eyes but has a blue-eyed child, what must his genotype be?
Give the typical sex-chromosome complement found in the cells of people with Turner syndrome, with Klinefelter syndrome, and with androgen-insensitivity syndrome. What is the sex-chromosome complement of triple-X females?
In mice, dwarfism is caused by an X-linked recessive allele, and pink coat is caused by an autosomal dominantallele (coats are normally brownish). If a dwarf femalefrom a pure line is crossed with a pink male from a pureline, what will be the phenotypic ratios in the F1 and F2 ineach sex? (Invent and define your own gene symbols.)
Suppose genetic analysis reveals a serious mutation in a gene in the green region of the left-hand copy of chromosome 9 in this individual. Where would you go look for another allele of this gene in this individual to see whether this individual is homozygous or heterozygous for this mutation?
Are mitotic recombinations and sister chromatid exchanges effective in producing genetic variability in an individual? in the offspring of individuals?
DNA sequencing of your own two β-globin genes (one from each of your two Chromosome 11s) reveals a mutation in one of the genes. given this information alone, should you worry about being a carrier of an inherited disease that could be passed on to your children? What other information would you like to have to assess your risk?
Pedigrees indicate that color blindness and which two forms of hemophilia are X-linked traits?
In humans, hypertrichosis of the ears is caused by a holandric gene while baldness vs. non-baldness is sex-influenced, controlled by a pair of autosomal alleles, and follows a male-dominant pattern of inheritance. Based on this information, can a normal non-bald daughter have a hypertrichosis bald father? Explain your reasoning and predict the genotypes.
Hemophilia is another example of an X-linked disease caused when a recessive allele (Xh) is expressed. If a normal male reproduces with a heterozygous normal female, what are the expected genotypes and phenotypes? Will any of their daughters develop hemophilia?
