What Is Crossing Over in Genetics?
A gene is defined as a unit of heredity that is passed along from one generation to the next, according to MedicineNet.com. Genes comprised short sequences of deoxyribonucleic acid, or DNA, and are arranged along chromosomes. Chromosomes are simply long...
Crossing over occurs during meiosis I and is the process where homologous
chromosomes pair up with each other and exchange different segments of their ...
An important fundamental of genetics is the idea of independent assortment. ...
Crossing over during meiosis allows recombination of genes. between ...
crossing over, process in genetics by which the two chromosomes of a
homologous pair exchange equal segments with each other. Crossing over

The idea that intrachromosomal recombinants were produced by some kind of
exchange of material between homologous chromosomes was a compelling one.
Crossing over of genes is a big factor in the genetic diversity of living things. Here
we will define the process of crossing over, explore the...
This ensures genetic variation in sexually reproducing organisms. Further
genetic variation comes from crossing over, which may occur during prophase I
Each chromatid contains a single molecule of DNA. So the problem of crossing
over is really a problem of swapping portions of adjacent DNA molecules.
