Crossing over is partly responsible for the genetic diversity in meiosis. Here we explain how it works and what significance it has in genetics. More videos at https://studyflix.de/! Have you ever wondered why your siblings have a different hair color than you? One reason for this could be so-called crossing over. A human's diploid cell contains 23 pairs of chromosomes. One chromosome comes from the mother and one from the father. Since the pairs (except for the male sex chromosomes) are the same size, shape and gene sequence, you can call them homologous chromosomes. However, the expression of these genes is different. For example, the father's chromosome can code for blue eye color and the mother's chromosome for brown eye color. In prophase 1 of meiosis, the homologous chromosomes cross over and randomly exchange certain gene sections (e.g. for hair color) with each other. This exchange ensures genetic diversity in eukaryotes. 00:15 Crossing Over simply explained 01:13 Crossing Over process 02:38 Significance of Crossing Over 03:46 The most important things at a glance ------------------------------------------------------------------------------------------ Click here for the chromosome mutation video: https://studyflix.de/biologie/chromos... ------------------------------------------------------------------------------------------ You can find more information on Facebook: / or on our website: https://studyflix.de/ Click here for the free Studyflix app: Play Store: https://play.google.com/store/apps/de...
