Duplicated homologous pair
WebOne set of the duplicated homologous chromosomes line up above and below the metaphase plate. Anaphase 1 –cell elongates to make room for the duplicated homologous chromosomal pairs to pull apart. This is the point the chromosome number goes from haploid to diploid. Notice the chromosomes are still duplicated. WebOct 4, 2024 · During the first division of meiosis, meiosis I, the homologous chromosomes are divided in a cell. As in mitosis, the DNA has replicated before meiosis, and all the chromosomes exist as sister chromatids. Each chromosome has a homologous pair, which represents the same portion of DNA but with different alleles.
