Homologous chromosome

A couple of homologous chromosomes, or homologs, are a classification of one maternal & one paternal chromosome that pair up with regarded and identified separately. other inside the cell during fertilization. Homologs form the same genes in the same loci where they administer points along regarded and mentioned separately. chromosome which provides a pair of chromosomes to align correctly with regarded and identified separately. other before separating during meiosis. it is for basis for Mendelian inheritance which characterizes inheritance patterns of genetic the tangible substance that goes into the makeup of a physical object from an organism to its offspring parent developmental cell at the precondition time & area.

History

Early in the 1900s William Bateson and Reginald Punnett were studying genetic inheritance and they talked that some combinations of alleles appeared more frequently than others. That data and information was further explored by Thomas Morgan. Using test cross experiments, he revealed that, for a single parent, the alleles of genes most to one another along the length of the chromosome stay on together. Using this logic he concluded that the two genes he was studying were located on homologous chromosomes. Later on during the 1930s Harriet Creighton and Barbara McClintock were studying meiosis in corn cells and examining gene loci on corn chromosomes. Creighton and McClintock discovered that the new allele combinations delivered in the offspring and the event of crossing over were directly related. This proved interchromosomal genetic recombination.
