Which of the following is TRUE at the end of telophase I in corn (2n = 20)?
A. Each cell has 20 chromosomes. B. Each chromosome is paired with its homologue. C. Centromeres connect homologous chromosomes. D. Each cell is diploid. E. Centromeres connect sister chromatids.
Consider a chromosome with ordered loci A (A/a), B (B/b), C (C/c), D (D/d), and E (E/e) where the letters in the parentheses indicate the alleles at loci
On a chromosome in which A, C, D, and E are coupling, a new allele arises at the locus B. This new allele B, has a negative effect on fitness. As a result, we would expect: a. the genetic variation at neighboring loci to decrease. b. the alleles A, C, D, and E may be lost due to background selection. c. the alleles A, C, D, and E may be lost due to genetic hitchhiking. d. A and B. e. All of the above.
