b.) Homologous chromosomes do not pair up during asexual cell division.
c.) Gametes have the same number of chromosomes as a somatic cell.
d.) Cell division would not be possible without the work of DNA Polymerase.

- 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.

Answer ; All human being's have 23 pairs of chromosome .Human males have 22 pairs at autosomes and coutain one or two types of sex chromosome .they are either X And Y .on contrary, females have 22 pairs of autosomes and contain only the X sex chromosome .the Sex of an individual is determined by the type of the male gametes (X or Y) , which fuses with the X chromosome of the female. Ic the fertilizing sperms is X , then the baby will be girl and if it is Y, then the baby will be boy .Hence , it is incorrect to blame a women for the gender of the child.arrow_forwardMacmillan Learning across generations.

The daughter cells produced in mitosis are genetically different from the parent cells, but have the same number of chromosomes, while these are genetically similar in case of meiosis and have fewer chromosomes. b.) The daughter cells produced in mitosis are genetically similar to the parent cells and have the same number of chromosomes, while these are genetically different in meiosis and have half the number of chromosomes. c.) The daughter cells produced in both cases are genetically similar to the parent cells, but in meiosis, there are fewer chromosomes. d.) The daughter cells produced in both cases are genetically different, but in mitosis, there are fewwer chromosomes in daughter cells. 2.)
