31. Sperm and egg cells are called: a. autosomes b. genosomes c. gametes d. Golgi bodies 3 Thomas (a man) knows that in his body, meiosis occurs in: a. only his brain b. only his white blood cells c. only his testes d. every cell in his body 33. Suppose that a human female is accidentally exposed to a poison at one of four different points in development. If the effect of the poison is that it interferes with meisosis, at which point in the lifespan would we expect it to have the most disruptive effect? a. in the prenatal period, since this is when ova are forming b. in the first year after birth, since this is when brain growth is most rapid c. during early adulthood, since this is when conception of a child is most likely to happen d. in older adulthood, since body cells are most vulnerable at the end of the lifespan 34. In women, ova are formed: a. about one every day after reaching puberty b. about one or two a month, every month after reaching puberty c. about 100 every day after reaching puberty d. during the prenatal period 35. Which of the following results from the process of meiosis? a. fertilized ovum b. alleles c. gametes d. proteins 36. Another term used to refer to either ova or sperm is: a. alleles b. gametes c. phenotypes d. proteins 37. The cell division process that results in the formation of gametes is called: a. meiosis b. gene imprinting c. transcription d. mitosis 38. The term used to describe alternate versions of the same gene is: a. alleles b. chromosomes c. autosomes d. gametes 39. The term that refers to an individual’s genetic make-up is __________; the term that refers to the physical characteristics that result from that genetic make-up is __________: a. autosomes; gametes b. gametes; autosomes c. phenotype; genotype d. genotype; phenotype 40. Suppose that the gene that determines how many fingers a person has is coded such that having 5 fingers is dominant and having 6 fingers is recessive. If a person’s mother has 5 fingers and his father has 6 fingers, what is the probability that he will be born with 6 fingers? a. 0 % b. 50 % c. 100 % d. the percent cannot be determined because we do not know if his mother is homozygous or heterozygous for this trait
