During amphimixis: a) Meiosis occurs. b) The ovum finishes meiosis II. b) Sperm becomes capacitated. d) Gametes are formed. e) The male and female pronuclei fuse. The gametes (sperm and ova) are produced by which organ of the reproductive tract? A. gonads B. autosomes C. external ge...

Gametes:Many multicellular organisms have two major types of cells, which are the somatic cells and the gametes. Somatic cells are the cells found throughout the body. In contrast, the germ cells are also called the 'sex cells' and are responsible for contributing to the creation of new ...
Spermatogenesis is the process by which male gametes are formed from spermatogonial stem cells and it is essential for the reliable transmission of genetic information between generations. To date, the dynamic transcriptional changes of defined populations of male germ cells in pigs have not been repor...
Oogenesis is the process by which the female gametes, or ova, are produced. Ova are haploid, which means it contain a single set of chromosomes, which ensures that when fertilization occurs, the resulting cell, after combining with the male gamete, will have the correct chromosome number. ...
All cells in the body are diploid, which means they have two copies of each chromosome. Humans have 23 pairs of chromosome; 1 set is from their mother, and 1 set is from their father. The gametes (sperm and oocytes) contain only one copy of the chromosomes; thus, they are called hapl...
Self Pollinationis the transfer of pollen grains from the anthers of a flower to the stigma of the same flower or of another flower born by the same plant. Self-pollination generally occurs inbisexual flowers. Since the male and female gametes that take part in fertilization are formed in th...
Plant reproduction is the process by which plants generate new individuals, or offspring. Reproduction is either sexual or asexual. Sexual reproduction is the formation of offspring by the fusion ofgametes. Asexual reproduction is the formation of offspring without the fusion of gametes. Sexual reprodu...
The process of cell division in which diploid cells are converted to haploid gametes is called. What are gametes? Where are gametes produced? What process produces four genetically distinct haploid daughter cells? Are gametes formed during asexual reproduction in plants?
