WebThe chromosome with a satellite is referred to as ‘SAT-chromosome’. There are at-least two SAT-chromosomes in each diploid nucleus. Many polyploid species, however, have only two SAT-chromosomes. For example, hexaploids wheat. Part # 6. Telomere: The tips or the terminal ends of chromosomes are called telomeres. WebThe tight pairing of the homologous chromosomes is called synapsis. In synapsis, the genes on the chromatids of the homologous chromosomes are aligned precisely with each other. ... Multiple crossovers in an arm of the chromosome have the same effect, exchanging segments of DNA to create recombinant chromosomes. ... Because there is …

WebMeiosis I halves the number of chromosomes and is also when crossing over happens. Meiosis II halves the amount of genetic information in each chromosome of each cell. The end result is four daughter cells called haploid cells. Haploid cells only have one set of chromosomes - half the number of chromosomes as the parent cell. WebApr 6, 2024 · The centromere helps to divide the chromosome into two portions called chromosomes arms. ... In this chromosome, the centromere is present and situated in the middle of the chromosome and divides it into equal arms. These chromosomes are observed as V shapes in the metaphase stage of cell division. iv) Acrocentric: In this type … WebIn eukaryotes, the chromosomes are present inside the nucleus in the form of large linear strands.
