Unit 5 Meiosis
1. Humans have a diploid number ( ) of . Which of the following statements best predicts the consequence if
meiosis did not occur during gametogenesis?
~ (A) The gametes would get larger from one generation to the next.
(B) The chromosome number would double with each generation.
(C) The chromosome number would be halved with each generation.
(D) The chromosome number would triple with each generation.
2.
Figure 1. Model of crossing over between homologous chromosomes, indicating crossing over rate of selected loci.
~
During prophase replicated homologous chromosomes pair up and undergo synapsis. What testable question is
generated regarding synapsis and genetic variability by Figure 1 ?
(A) Is the distance between two gene loci related to crossover rate?
(B) Does crossing over occur more often in some chromosomes than in others?
(C) Is crossing over inhibited by methylation?
(D) Is crossing over promoted by methylation?
~
3. Scientists have found that methylation suppresses crossing-over in the fungus Ascobolus immersus. Which of
the following questions is most appropriately raised by this specific observation?
(A) Is the level of genetic variation in the gametes related to the amount of methylation observed?
(B) Without crossing-over, will gametes be viable and be able to produce zygotes?
(C) Does methylation result in shorter chromosomes?
(D) Is this species of fungus a diploid organism?
