Gametes are formed in the reproductive organs through meiosis. During the process the gamete chromosomes are first duplicated, then the cells divide twice, producing cells that have one set of chromosomes, called haploid. When two individual haploid gametes fuse to produce offspring, a diploid cell...
What is the process of forming organs called? Give two examples in each case of organs or tissues in which you would expect (a) meiosis, (b) mitosis to be taking place. What are the formed elements? 2. What happens to the sperm there? ___ What...
Gametes are an organism's reproductive cells and have also been referred to as "sex cells." Male gametes are called sperm; in females, they are called "ova" or egg cells. Gametes are haploid cells, which means that each cell carries one copy of each chro
What is the term for the structure that is a ball of cells resulting from the division of a fertilized ovum, and from which a blastula is formed? Process that produces haploid sperm from diploid stem cells: ___ Formation (meiosis) of female gametes (oocytes): ___ Gametes are: a. allo...
In some fish and amphibians, unreduced gametes are often formed by spindle misdivision with subsequent reten- tion of a secondary polar body4. In addition, chromosome doubling (two rounds of endo-reduplication instead of one) or fusion of two nuclei before meiosis is known to produce unreduced...

All stages of sperm development were observed in mature testes, which are bordered by a layer of fibrous connective tissue. The primary spermatogonium produces 64 spermatids, grouped as a cytophore. The process of spermiogenesis occurs at the periphery of the cytophore, when the sperm body is...
Are diploid cells formed when a sperm fertilizes an egg? How is an embryo different than a somatic cell? How do somatic cells get created from the gametes? Do germline cells create somatic cells? Are sex chromosomes somatic cells? In meiosis of human gametes (specifically meiosis 1), are ...
About ___ weeks after conception, embryo's ovaries or testes have formed although the embryo's sex is not apparent by ultrasound. a. two b. four c. six d. eight You are trying to determine which of two terms is related to identical twins. You see "monozygotic" and "dizy...
