VARIATIONS IN GENE EXPRESSION In humans, the glucose-6-phosphate dehydrogenase (G6PD) gene involved in sugar metabolism is X-linked. The dominant allele (G) codes for fast enzymes for normal cell functioning while the recessive allele (g) codes for slow enzymes, which are responsible for the reduced enzymatic activity of cells. However, the presence of slow enzymes has minimal effect in the overall functioning of heterozygotes, thus normal. Recessives, however, are more prone to oxidative reactions that speed up the cell damaging process, thus weak (but not lethal). If random inactivation occurs during dosage compensation, what would be the genotypes and phenotypes of the children of a heterozygous mother and a recessive father? Show COMPLETE cross.

Equalizing the Expression of X Chromosome Genes in Males and Females Individuals with an XXY genotype are sterile males. If one X is inactivated early in embryogenesis, the genotype of the individual effectively becomes XY. Why will this individual not develop as a normal male?

This pedigree depicts the inheritance of the mitochondrial disease Leber hereditary optic neuropathy (LHON). Individual I-1 does not show any symptoms of LHON, whereas her daughter and all three of her grandchildren are affected. Provide two explanations for this.
GENETICS In a sexually reproducing diploid organism in which 2n=6, a normal meiocyte in reduction should exhibit a total of 3 bivalents at the metaphase plate. Consider the following organism in the previous statement. if there is no crossing over, the number of possible haploids (gamete) genotypes generated by "chromosome shuffling" during meiosis is _____?
Some sweet-pea plants have purple flowers and others have white flowers. A homozygous variety of sweet pea that has purple flowers is crossed with a homozygous variety that has white flowers. All the F1have purple flowers. When these F1 self-fertilize, the F2 appear in a ratio of 916 purple to 716 white. a.Draw a hypothetical biochemical pathway to explain the production of purple and white flowers in sweet peas.
Please explain mitochondrial DNA inheritance . How is it inherited ? Why is it predisposed to mutations ? How can one identical twin be normal but the other identical twin have a mitochondrial disease ?
In mice, the autosomal locus coding for the β-globinchain of hemoglobin is 1 m.u. from the albino locus. Assume for the moment that the same is true in humans. The disease sickle-cell anemia is the result ofhomozygosity for a particular mutation in theβ-globin gene.a. A son is born to an albino man and a woman withsickle-cell anemia. What kinds of gametes will theson form, and in what proportions?b. A daughter is born to a normal man and a womanwho has both albinism and sickle-cell anemia.What kinds of gametes will the daughter form,and in what proportions?c. If the son in part (a) grows up and marries thedaughter in part (b), what is the probability that achild of theirs will be an albino with sickle-cellanemia?
A rare blinding disease that has a relation to dengenerative factors is partially penetrant. In the following pedigrees for two families, the affected symptomatic individuals (black circles and squares) have been diagnosed with this disease due to the mutation in mitochondrial DNA m.14484T>C. If III.4 is homoplasmic for m.14484T>C in hair, blood, urine and other tissues examined. What will occur with IV.7 then?
Gene Interaction and Epistasis Hair color is due to the presence of melanin. There are two types of melanin produced by melanocytes. One is eumelanin, which is responsible for black (homozygous), brown (heterozygous), and blond (recessive) hair colors. The other is pheomelanin, which is responsible for red hair color. During melanin synthesis, MCR1gene converts pheomelanin to eumelanin. However, a variant of the MCR1 gene (MCR1variant), prevents this conversion. A cross between a blond-haired mother and a red-haired father produced 100% brown-haired children. When they came of age, one child married a double heterozygote, and both were blessed with 7 children; 2 with black hair, 2 with brown hair, 1 with blond hair, and 2 with red hair.
