Meiosis is a special form of cell division that maintains the correct number of chromosomes in gamete cells, proceeding continuously through several phases. Meiosis I is the phase in which two haploid cells are produced from a single diploid cell. What happens during the pachynema stage of ...

How many pairs of homologous chromosomes would be present in a cell undergoing metaphase II? How many chromosomes are in a gamete? How many chromosomes are in a human somatic cell during anaphase? How many chromatids are in a human somatic cell?
Similar results are obtained in models with haploid sex-determination and with autogamy. These two processes, however, may help to maintain many sexes indirectly by preventing the accumulation of recessive lethal mutations on sex chromosomes. The relationship of these models to models of self-...
Chromosomes and Ploidy: Ploidy refers to the number of sets of each chromosome that are present in the cells of an organism. It determines the number of alleles that an organism can carry of each gene. An organism can carry only one of each chromosome, or two copies, or six or more...
The genomes of a monogenic fly: views of primitive sex chromosomes Article Introduction Insects (Insecta) represent the largest group of animal species with worldwide distributions1. Most insects reproduce sexually and, apart from occasional developmental anomalies, they appear to be obligately gonocho...
Because plants do not possess a defined germline, deleterious somatic mutations can be passed to gametes, and a large number of cell divisions separating zygote from gamete formation may lead to many mutations in long-lived plants. We sequenced the genome of two terminal branches of a 234-year...
