In humans, the female have all the 23 pairs of homologous chromosomes … WebSolution Verified by Toppr Correct option is B) Synapsis is the pairing of two homologous chromosomes that occurs during meiosis. It allows matching-up of homologous pairs prior to their segregation, and possible chromosomal crossover between them. Synapsis takes place during prophase I of meiosis.
WebPairing occurs in a region of the sex chromosomes which is containing homologous genes, termed the “pseudoautosomal region” (PAR).
WebThe most common mechanism for genomic deletions/duplications is homologous non allelic pairing, also known as non-allelic homologous recombination (NAHR). This occurs when two different regions of DNA that have a high degree of similarity align with each other during meiosis, leading to unequal crossover and deletion or duplication of the affected … does purpose go in abstract or introductionChromosomes are linear arrangements of condensed deoxyribonucleic acid (DNA) and histone proteins, which form a complex called chromatin.
