meiotic in Biological Definition

Meiosis

... article is defined in the article on mitosis .) As described earlier, meiotic nuclear division consists of two stages, called meiosis I and meiosis ... of a sister chromatid pair, as aforementioned. Telophase The first meiotic division effectively ends when the centromeres arrive at the poles. Each ...

Spermatogenesis

... become primary spermatocytes . Primary spermatocytes go through a meiotic division to become secondary spermatocytes , which undergo another meiotic division to become spermatids . Type A spermatogonia stay as ...

Cell growth

... its DNA. These two types of cell reproduction produced two daughter cells that have the same number of chromosomes as the parental cell. After meiotic cell reproduction the four daughter cells have half the number of chromosomes that the parental cell originally had. This is the haploid amount of ...

Polymerase chain reaction

... alleles at 2 or more SNPs occur together on the same chromosome [Linkage Disequilibrium]) or detection of recombinant chromosomes and the study of meiotic recombination. Comparison of gene expression Researchers have used traditional PCR as a way to estimate changes in the amount of a gene's ...

Zygote

... a single diploid cell called the zygote . Animal zygotes undergo mitotic cell divisions to become an embryo . Other organisms may undergo meiotic cell division at this time (for more information refer to biological life cycles ). Twins and multiple births can be monozygotic ...
