Do sex cells undergo mitosis?Mitosis:A cell prepares for cell division by replicating its chromosomes, segregating them, and creating two identical nuclei during the mitotic phase. The cell's contents are often evenly divided into two daughter cells with identical genomes after mitosis....
Can meiosis occur in somatic cells? In meiosis, what makes up a tetrad? Why don't somatic cell mutations affect phenotype? How do zygotes form somatic cells? Why is it necessary to reduce the number of chromosomes in gametes, but not in other cells?
What type of cells undergo binary fission, somatic or gametes? What chromosomes exist in somatic cells? Are somatic stem cells pluripotent? Are follicular cells germ cells or somatic cells? Is embryonic development caused by mitosis or meiosis? How do the terms somatic cells, gamete, zygote, and...
Spirogyra and Sirogonium are reported to produce diploid gametes with synapsis of homologous chromosomes before fusion of gametic nuclei; Closterium ehrenbergii is reported to undergo chromosome reduction both before and after syngamy; and zygotes of Coleochaete scutata are reported to replicate their...
A total of 42 karyoplasts isolated from 13 quartets were fused to generate 41 (97.6%) zygotes that developed to 33 (80.5%) blastocysts (Fig. 5B). Transfer of 30 blastocysts into the uterine horns of pseudopregnant females yielded 12 offspring (40.0%). Such pseudoblastomeres generated by ...

How do cells created through meiosis differ from somatic cells? When does replication occur in somatic cells? Is a stem cell a somatic cell? Are germ cells haploid or diploid? Are gametes sex cells or zygotes? Is a heart cell a gamete or somatic? What can mutate germline cells? Do somat...
