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?
Which of the following statements is incorrect? a. Some gene expression patterns can be passed to an individual's offspring. b. Expression of a master regulator triggers a gene express.ion cascade. c. X chromosome inactivation is necessary for normal development of male mammals.
How does NF-kB induce gene expression? A small, hydrophobic ligand binds to NF-kB, activating it. Phosphorylation of the inhibitor Ik-B dissociates the complex between it and NF- kB, and allows NF-kB to enter the nucleus and stimulate transcription. NF-kB is phosphorylated and is then free to enter the nucleus and bind DNA. NF-kB is a kinase that phosphorylates a transcription factor that binds DNA and promotes protein production.

Almost all calico cats (one is pictured in FIGURE 10.7B) are female. Why? B When this calico cat was an embryo, one of the two X chromosomes was inactivated in each of her cells. The descendants of the cells formed her adult body, which is a mosaic for expression of X chromosome genes. Black fur arises in patches where genes on the X chromosome inherited from one parent are expressed; orange fur arises in patches where genes on the X chromosome inherited from the other parent are expressed.

The ABO blood groups in humans are expressed as the IAlB, and IAalleles. The allele encodes the A blood group antigen, lBencodes B, and i encodes O. Both A and B are dominant to O. If a heterozygous blood type A parent (IAi) and a heterozygous blood type B parent (IBi) mate, one quarter of their offspring will have AB blood type (IAIB) in which both antigens are expressed equally. Therefore, ABO blood groups are an example of: multiple alleles and incomplete dominance codominance and incomplete dominance incomplete dominance only multiple alleles and codominance

During anaphase of mitosis, cyclin is degraded, allowing mitosis to end.
Effect of Paternal Grandmothers Food Supply on Infant Mortality Researchers are investigating long- reaching epigenetic effects of starvation, in part because historical data on periods of famine are widely available. Before the industrial revolution, a failed harvest in one autumn typically led to severe food shortages the following winter. A retrospective study has correlated female infant mortality at certain ages with the abundance of food during the paternal grandmothers childhood. FIGURE 10.12 shows some of the results of this study. FIGURE 10.12 Graph showing the relative risk of early death of a female child, correlated with the age at which her paternal grandmother experienced a winter with a food supply that was scarce (blue) or abundant (red) during childhood. The dotted line represents no difference in risk of morality. A value above the line means an increases risk; one below the line indicates a reduced risk. 1. Compare the mortality of girls whose paternal grandmothers ate well at age 2 with that of those who experienced famine at the same age. Which girl was more likely to die early? How much more likely was she to die?
