WebJan 24, 2024 · A pair of homologous chromosomes contains chromosomes of similar length, gene position, and centromere location. Chromosomes are important molecules because they contain DNA and genetic instructions for the direction of all cell activity. They also carry genes that determine individual traits that can be inherited through reproduction. Each chromosome in the pair contains the same genes in the same order, and place, along the length of the chromosome. For a given gene, if the two chromosomes contain the same allele, they, and the organism, are homozygous with respect to that gene. If the alleles are different, they, and the organism, are … See more An allele is a variation of the same sequence of nucleotides at the same place on a long DNA molecule, as described in leading textbooks on genetics and evolution.

WebA sister chromatid refers to the identical copies ( chromatids) formed by the DNA replication of a chromosome, with both copies joined together by a common centromere. In other words, a sister chromatid may also be said to be 'one-half' of the duplicated chromosome. A pair of sister chromatids is called a dyad.

WebApr 6, 2024 · Key Takeaways. Homologous chromosomes are pairs of chromosomes with the same genes but possibly different alleles, whereas sister chromatids are identical copies of a single chromosome. Homologous chromosomes are inherited from each parent, while sister chromatids are created during DNA replication in the S phase of the cell cycle.
