Chromosomes are randomly partitioned during b , contributing to genetic diversity. . . Although organisms with linear chromosomes must solve the problem of fully replicating their chromosome ends, this chromosome configuration has emerged repeatedly during bacterial evolution and is evident in three divergent bacterial phyla. The benefit usually ascribed to this topology is the abilit … 2014-03-13 2018-07-30 Chromosomes are in unseparated, sister-chromatid form, at the end of the phase(s) _____.

Genetic diversity is expected to be higher in recombining regions than in non-recombining regions because recombination reduces the effect of linked selection. In this study, we investigate patterns of genetic diversity in noncoding regions across the entire X chromosome of a global sample of 26 unrelated genetic females. During crossing over, sections of maternal and paternal chromosomes are cut, exchanged and spliced into place, with the resulting new chromosomes having different assortments of genes.

47. Sister chromatids separate during _____. Chromosomes are randomly partitioned during _____, contributing to genetic diversity. Crossing over (genetic recombination) occurs in _____. Answer: 1, 2, 3, 5; 2; 4, 6; 2; 1; Section 2.2-2.3.

Sex chromosomes turn over rapidly in some taxonomic groups, such as fishes, where closely related species have different sex chromosomes –.Sex chromosome turnover can occur via transposition of an existing sex-determination gene to an autosome, the evolution of a new sex-determination gene on an autosome, and translocation between an autosome and a sex chromosome , .
