A gamaete is a --
Reproductive cell (a gamete or a sperm).
Gametes are produced by reproductive organs of male and female, Ovary produces egg and testis produces sperm.
10.
False.
Gametes are not created by mitosis. They are made by meiosis which is a reductional division. The meiosis process produces gametes which convert the diploid cell in to a haploid gamete.

Nameindulia Los Drosophila Genetics Predictions-L113 (20 pts.) Part I. Meiosis and Punnett Squares Remember, whenever you use Punnett Squares to solve genetics problems, be sure you are completing each of the following steps: 1) Identify the genotypes of the parents. 2) For the specific traits of interest, figure out what kinds of haploid gametes each parent can make. In each gamete, there should be one allele for each trait of interest. If there is more than one trait, make sure...
