Homologous chromosomes in a sentence

Homologous chromosome n. A homologous chromosome pertains to one of a pair of chromosomes with the same gene sequence, loci, chromosomal length, and centromere location. A homologous pair consists of one paternal and one maternal chromosome. In humans, there are a total of 46 chromosomes in the nucleus of a somatic cell. Each maternal chromosome has a corresponding paternal chromosome; they pair up during meiosis. Typically, a female will have 23 homologous chromosomes whereas a male will have That is because the sex chromosomes, X and Y, in males are not homologous. The pairing up of homologous chromosomes during meiosis is important to promote genetic variation. Because of the genetic recombination that occurs between homologous pairs at meiosis, the resulting haploid gametes contain chromosomes that are genetically different from each other. This amplifies the gene pool, thereby, increasing the chances of acquiring genes essential to biological fitness and survival. Want to know about homologous chromosome? In biology, homologous chromosomes are paired chromosomes. They essentially have the same gene sequence, loci gene position , centromere location, and chromosomal length.

In animals, cells are enclosed by a membrane within which is the cytoplasm that contains cellular organelles, including the nucleus. The chromosomes in a homologous pair each have the same Gene A segment of DNA that encodes for a particular polypeptide. That is, the DNA sequence that contains the biological instructions for the production of a polypeptide chain, usually a specific protein or component of a protein. Some of the variants in these alleles might have functional implications while others will not.

Crossover recombination and the formation of chiasmata normally ensure the proper segregation of homologous chromosomes during the first meiotic division. The identical chromatids are specifically called sister chromatids to distinguish them from the so-called non-sister chromatids. Japanese English to Japanese.
