WebOct 27, 2024 · Prophase I of meiosis I is a process that involves five different stages during which genetic material in the form of alleles crosses over and recombines to form non-identical haploid chromatids. … Web1) During mitosis, homologous chromosomes behave independently (maternal and paternal). 1) During meiosis, homologous chromosomes pair to form a bivalent during early prophase I. 2) Chromosomes are held in different ways. In mitosis, sister chromatids are held by cohesin. 2) Bivalents are held together by chiasmata (individual chiasma) … fm1 christmas

WebPairing of homologus chromosomes in a diploid cell, as occurs during prophase I of meiosis. Where crossing over can occur. crossing over Process in which homologous chromosomes exchange portions of their chromatids during meiosis. Meiosis Cell division that produces reproductive cells (sperm & egg) in sexually reproducing organisms. Mitosis WebThe X and the Y chromosomes are called sex chromosomes because. A. females have X chromosomes and males have Y chromosomes. B. they are present only when cells undergo meiosis. C. genes located on the chromosomes play a role in determining the sex of the individual. D. they are formed only as a result of fertilization. WebProphase I (Stage 2) The DNA starts to coil itself up into visible chromosomes. The copies of each chromosome (sister chromatids) are connected together by a centromere. During the end of this stage the nuclear membrane starts to dissolve, centrosomes move towards the poles, and spindle fibers start to form. Crossing over occurs during this stage. fm1 court form
