27 de abr. de 2017 · Crossing over is the exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis, which results in new allelic combinations in the daughter cells.
El sobrecruzamiento, crossing-over o entrecruzamiento cromosómico es el proceso por el cual las cromátidas de cromosomas homólogos se aparean e intercambian secciones de su ADN durante la profase I de la meiosis.
Hace 4 días · Crossing over is a cellular process that happens during meiosis when chromosomes of the same type are lined up. When two chromosomes — one from the mother and one from the father — line up, parts of the chromosome can be switched.
El intercambio de fragmentos de cromátidas homólogas se llama crossing over y da lugar al intercambio de segmentos homólogos de ADN entre las dos cromátidas, que se produce con una rotura y un empalme que preserva la información genética.
Chromosomal crossover, or crossing over, is the exchange of genetic material during sexual reproduction between two homologous chromosomes' non-sister chromatids that results in recombinant chromosomes.
Meiosis is a process where germ cells divide to produce gametes, such as sperm and egg cells. In prophase I of meiosis, chromosomes condense and homologous recombination takes place, leading to genetic variation through chromosomal crossover.
15 de dic. de 2023 · Crossing over is the refers to the interchange of genetic material between non-sister chromatids of homologous chromosomes involving breakage and reunion at precise point during meiotic prophase (pachytene), which results in new allelic combinations in the daughter cells.
