Gametid
A gametid is a complementary gamete to the gamete that gives rise to a zygote after conception. For each gamete that makes a zygote, there is a complementary gamete, or gametid. There are gametids for both egg and sperm gametes. wikipedia.org

Four-gamete test
In population genetics, the four-gamete test is a method for detecting historical recombination events. Description Given a set of four or more sampled haploid chromosomes, the four-gamete test (FGT) detects recombination events by locating pairs of segregating wikipedia.org

DNA replication and combination > "Each gamete is genetically unique because the DNA of the parent cell is shuffled before the cell divides. This helps ensure that the new organisms formed as a result of sexual reprod...
Your gamete is haploid and has therefore only one of the two paired chromosomes. So for every chromosome pair there are 2 possible chromosomes. The gamete from the sexual mating partner also has 223 possibilites to arrange chromosomes.

National Gamete Donation Trust
The National Gamete Donation Service (NGDS), now known as the SEED Trust, raises awareness of the national shortage of sperm, egg and embryo donors in The name changed to the National Gamete Donation Service. In 2019, the name changed again to the SEED Trust (Sperm, Egg and Embryo Donation Trust). wikipedia.org

Are chromosomes from each parent split between gametes with equal probability (esp. in humans)? I've recently read a little on Wikipedia about genetics, but I can't find a direct answer to this question. My rough und...
Any chromosome in a gamete will be a mosaic of the maternal and paternal versions. In this sense the chromosome is not the unit of inheritance.

Oogamy
In oogamy the large female gamete (also known as ovum) is immotile, while the small male gamete (also known as sperm) is mobile. See also Gamete Anisogamy Isogamy References Reproductive system Germ cells wikipedia.org

Anisogamy
The smaller gamete is male, a sperm cell, whereas the larger gamete is female, typically an egg cell. Some recent theoretical work has challenged the gamete competition theory, by showing that gamete limitation by itself can lead to the divergence of gamete wikipedia.org

Do all species have asymmetric female meiosis? In all the examples I can think of, (mostly vertebrate), female meiosis, or oogenesis, only haploid gamete is produced while the other cell divisions result in polar bodi...
Plant meiosis gives rise to four megaspores but usually upto three of them die by apoptosis leaving only one megaspore. But they are symmetric and three of them need not die all the time as it seems [REF]. Plasmodium being a haploid organism undergoes meiosis after fusion of gametocytes. Sexual diff...
