1.The reproductive organ in female animals that produces eggs and the sex hormones estrogen and progesterone. In most vertebrate animals, the ovaries occur in pairs. 2.The part of a flower pistil that contains ovules. The ovary is located at the base of the pistil and ripens into a fruit ...
We posit an apomictic allele that arrests female meiosis in diploids, so that the plant produces diploid egg cells that can develop without fertilization, but haploid pollen. We propose occasional fertilization of diploid egg cells by haploid pollen, resulting in triploid apomicts that produce ...
For a more complete account the male is the heterozygous sex, whereas in moths we refer the reader to the author's book, "Me- and birds it is the female which produces the two chanismus und Physiologic der Geschlechtsbestim- kinds of gametes. The possible meaning of these ung" (Born...
What is the difference between somatic cells and gametes? Define haploid cell Mitosis produces which cell type? Haploid, diploid, chromosome, gamet? How are male and female gamete production different? What are replicated chromosomes? What are pseudoautosomal regions on the sex chromosomes? What is...
Importantly, two pollen tubes were targeted with higher percentages when both female gametes were unfertilized (∼80%, reported previously by Kasahara et al., 2012). This implies that the two signaling pathways, the egg cell pathway and central cell pathway, are independent of each other and...

(SI). This inducer stimulates the gonidia to produce egg- or sperm bearing sexual spheroids. The fusion of gametes results in the formation of a desiccation-resistant, over wintering zygospore, which germinates and undergoes meiosis when favourable conditions return in the next spring. In this ...
Define the following body part: "ovary". What is the main function of the ovary in the female reproductive system? During the first trimester, hCG produced from the chorion maintains the corpus luteum. What is the purpose of maintaining the corpus luteum? a. The corpus luteum produces relaxin...
