Similarity bewtween characteristics and traits because if a shared ancestory. Link : http://en.wikipedia.org/wiki/Homologous_structure Body parts that are similar in structure and function in different animals
Homologous means similar to but not the same thing, as a squirrel's foreleg is homologous to a human's arm.
Homologous means that there is a body part that has the same makeup of a body part of a different organism. Therefore, mosquitos and horseflies have mouth parts that are homologous.
diploid
the gene's alleles are found in matched chromosome pairs
The word homologous is not derived from the Latin word homo meaning man. It is derived from a Greek word meaning same. So homologous implies something that is consistent throughout, or to many things that are the same.
Homologous pairs are called tetrads because these pairs are maid up of a four-part structure. Tetrad literally means a group of four.
They have homologous chromosomes
homologous
If a species has homologous chromosomes, it means that each chromosome in a pair has a corresponding partner with similar structure and gene content. One chromosome of each pair is inherited from the mother and the other from the father. These homologous chromosomes may carry different alleles for certain genes, which can contribute to genetic variation within the species. This arrangement is essential for processes like meiosis, where homologous chromosomes pair up and exchange genetic information.
I learned about homologous and heterozygous structures in Biology.
There are 2n possible homologous chromosome alignments, where n is the number of homologous pairs of chromosomes.
If a species has homologous chromosomes, it means that they have pairs of chromosomes with similar genes in the same order. This can facilitate genetic diversity through processes like crossing over during meiosis. Homologous chromosomes are essential for genetic variation and proper segregation of genetic material during cell division.
