30 de jun. de 2024 · El cruzamiento, en relación con la genética y la genómica, se refiere al intercambio de ADN entre pares de cromosomas homólogos (uno de cada progenitor) que ocurren durante el desarrollo de los óvulos y los espermatozoides (meiosis).

Hace 5 días · Durante la formación de los óvulos y los espermatozoides (meiosis), pares de cromosomas del progenitor masculino y el femenino se alinean de forma que secuencias parecidas de ADN puedan cruzarse, o intercambiarse, de un cromosoma al otro.
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.
Hace 6 días · Crossing over is an extremely important mechanism for increasing genetic diversity in animals. The frequency with which crossing over occurs between any two linked genes is proportional to the distance between them.
Hace 5 días · Crossing over plays a critical role in increasing the genetic variation among offspring of sexual reproduction. Crossing over is unique to meiosis. Its occurrence depends on specific events early in prophase I, and it has important consequences for the rest of meiosis and beyond.
Hace 3 días · With the exception of deficiencies (loss of chromosome ends), chromosome aberrations are caused by illegitimate crossing over, i.e. crossing over at non-homologous sites (e.g. after exposure to radiation, by chemical mutagens). Crossing over leads to deletion (loss of a middle piece), inversion (exchange of the two ends) or formation of ring ...

If a sperm cell contains 8 chromosomes, it comes from an animal whose regular body cells have _____ chromosomes.
