The homologous chromosomes. Introduction: Chromosomes are the thread-like structures in the nucleus of a cell containing the genetic material in the form of the DNA (deoxyribonucleic acid). Each chromosome is made up of tightly packed DNA coiled around the histone proteins. Each cell has 23 pairs of chromosomes or 46 chromosomes. Homologous chromosomes are a pair of chromosomes that are similar, carry the same genetic information. One of the pairs is derived from mother (maternal) and the other one from the father (paternal).

Homologous chromosomes are a pair of chromosomes that are similar, carry the same genetic information. One of the pairs is derived from mother (maternal) and the other one from the father (paternal).

Expert Solution & Answer

Explanation of Solution

Homologous chromosomes can be defined as a set of 1 maternal and 1 paternal chromosome, which is paired up together in the cell during the meiosis. They are similar in the length, position of the centromere and have the same genes in the same loci, but, the alleles may be different. The first 22 pairs of the chromosomes (autosomes) in humans are homologous in nature. In the females, the 23^rd pair is also homologous, as both are X chromosome, but in males, they are not homologous, as one of them is X and the other is Y.

Conclusion

Homologous chromosomes are very important in meiosis as they allow recombination and segregation of the genetic material from the parents to the offspring.

Imagine you are a botanist. Below are characteristics of a never-before described plant species recently identified as part of the ‘All Taxa Biodiversity Inventory’ (ATBI). Field Notes: Specimen collected from shaded area along stream in South Cumberland State Park (Grundy County, TN). Laboratory Analysis: Body: Large leaves emerging from underground rhizome. Size: 63 cm Chromosomal Analysis: Plant body is diploid—chromosome number of 44. Lignin test: Positive Cuticle: Present Leaves: Present—large with branched veins. Underside has sori (containing haploid spores). Roots: Present—branch from the inside. Stem: Present—vascular tissue (xylem & phloem) present. Life History: Diploid sporophyte dominant generation. Haploid spores germinate into heart-shaped, haploid, gametophyte. Water required for fertilization; no seed is produced. Diploid zygote develops into sporophyte.
