How To Use Gametogenesis In A Sentence
-
The formation of the female gamete (megagamete or egg cell) can be subdivided into two stages, megasporogenesis and megagametogenesis.
-
The whiteness was a genomic "error" during the process gametogenesis or recombination, and only later turned out to be pertinent to environmental adaptation.
Darwin's Defenders Go Neo-Lamarckian
-
Flies homozygous for such hypomorphic mutations reach adulthood, but often exhibit defects during the proliferative stages of gametogenesis.
-
Sporulation in single-celled eukaryotes such as yeasts is a morphogenetic process equivalent to gametogenesis, because an ascospore is a highly specialized cell and its formation is preceded by meiotic nuclear division.
-
Males arise spontaneously through nondisjunction of the X chromosome during gametogenesis and the subsequent fusion with a normal gamete, yielding an XO individual.
-
We had to backtrack a bit to talk about gametogenesis and fertilization, but I didn't mind.
Late night variety pak
-
Homologous chromosomes are fully aligned at the pachytene stage, and germ cells survive to complete meiosis and gametogenesis with high efficiency.
-
AGO9 lead to the differentiation of multiple gametic cells that are able to initiate gametogenesis.

-
A causative role for AHA3 in male gametogenesis was proven by complementation with a normal transgenic gene and rescue of the mutant phenotype back to wild type.
-
The law of segregation is explained by the fact that during gametogenesis, each gamete (sex cell) receives only one of each chromosome pair from its parent organism.
Population Genetics
-
A recessive character is the absence of some positive character, and if in the cell-divisions of gametogenesis the factor for the positive character passes wholly into one cell, the other will be without it, will not 'carry' that factor.
Hormones and Heredity
-
In both females and males, androgens but also estrogens play an important role in gametogenesis.

GENETIC CONTINUITY
-
Gametogenesis appeared to be unaffected by hypophysectomy suggesting that the hagfish gonad was independent of hypophysial gonadotropic control.
-
Meiosis is the component of gametogenesis responsible for the segregation of homologous chromosomes into haploid gametes.
-
Pond-breeding urodeles, such as A. texanum, exhibit postnuptial gametogenesis.
-
Together these studies indicate the sex steroids are likely to play a role in regulating anthozoan gametogenesis and/or spawning.
-
In the ovules of most sexual flowering plants female gametogenesis is initiated from a single surviving gametic cell, the functional megaspore, formed after meiosis of the somatically derived megaspore mother cell (MMC) 1, 2.
