Question 22

Question
In a fictional species of insect, eye shape is determined by a single gene with two alleles. An insect homozygous for round eyes is crossed with an insect homozygous for elongated eyes. All the F1 offspring have oval eyes. If members of the F1 generation are crossed, what percent of their offspring (F2) are expected to have round eyes?
Answer
  • 100 percent
  • 75 percent
  • 50 percent
  • 25 percent

Question 23

Question
In drosophila, normal wings (N) are dominant to vestigial wings (n) and a grey body (G) is dominant to a black body (g). The offspring of a particular cross produced 412 flies with normal wings, and 192 flies with grey bodies and 220 flies with black bodies. Which were most likely the genotypes of the parents?
Answer
  • NnGg x NnGg
  • NnGg x NNGg
  • Nngg x nnGg
  • NnGg x NNgg
  • NNgg x nnGG

Question 24

Question
In drosophila, normal wings (N) are dominant to vestigial wings (n), and a grey body (G) is dominant to a black body (g). A cross between heterozygote flies and homozygote recessive flies produced 402 grey, normal-winged flies, 416 black, vestigial-winged flies, 90 black, normal winged flies, and 92 grey, vestigial winged flies. Which of the following best explains these results?
Answer
  • Independent assortment of homologous chromosomes
  • Segregation of alleles during gamete formation
  • Crossing-over between liked genes
  • Heterozygotes crossed with homozygotes are expected to have these ratios.
  • Some of the flies must have mated with flies that weren't part of the experiment.

Question 25

Question
Which of the following best describes the relationship between linked genes and the rate of crossing-over between them?
Answer
  • Two genes far apart on a chromosome will not appear to assort independently.
  • The distance between the genes is inversely proportional to their rate of crossing-over.
  • The recombination frequency is directly proportional to the distance between genes.
  • Two genes on different chromosomes may be linked if they are inherited together.
  • Chromosomes that contain sex-linked genes do not assort independently.

Question 26

Question
Human spermatogenesis produced four sperm, two with 24 chromosomes and two with 22 chromosomes. The nondisjunction event that caused this probably occurred during which phase of meiosis?
Answer
  • S phase
  • Meiosis I
  • Anaphase II
