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...
Spermatogenesis and oogenesis are the processes by which male and female gametes are produced, respectively. Spermatogenesis is the process of sperm production in males, while oogenesis is the process of ootid production in females. Spermatogenesis begins at puberty, while oogenesis begins prenatally. ...
Q.2. Which process leads to the formation of gametes? Ans:When two distinct haploid cells, male and female, are formed, it is known as gametogenesis. The entire process takes place in the pre-fertilization stage of sexual reproduction. ...
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...
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?
Answer and Explanation:1 Gametes are produced by meiosis. Meiosis, also called reduction division is the process of cell division which results in the generation of daughter...
