Why is meiosis necessary in organisms that reproduce sexually?

WebExpert Answer. crossing over occurs during meiosis. Chromosome are replicated before meiosis. During …. Question 13 Crossing over that contributes to genetic diversity occurs between two homologous chromosomes. two non-homologous chromosomes. two sister chromatids. two tetrads. all of the above. Web2 uur geleden · During meiosis, cells combine one round of DNA replication with two rounds of chromosome segregation, all of which is tightly regulated to ensure that gametes inherit the correct number of chromosomes. Errors in meiosis can lead to aneuploid gametes that cause infertility, birth defects and miscarriages [ 1 ]. WebIt is demonstrated that ecl3+ is induced by phosphate starvation, similar to its chromosomally neighboring genes, pho1+ and pho84+, which respectively encode an extracellular acid phosphatase and an inorganic phosphate transporter. ABSTRACT In Schizosaccharomyces pombe, ecl family genes are induced by several signals, such as … lindsay beer store hours today
