What are male gametes Study guides, Class notes & Summaries

Heterozygous - When two different alleles combine to form a trait. Example: A tall person and a short person have a child who is short. The short allele is dominant so the child grew up to be short. Gene - A section of DNA that controls a certain trait. Example: Eye color. Dominant - Determines the expression of a trait (visually). Example: Brown eyes, dark hair. Homozygous - A homozygous trait is when two of the same kind of alleles combine to form a trait. Example: When two tall...

gonads - ANSWER In males and females, structure that produces gametes. gametes - ANSWER Reproductive cells spermatozoa - ANSWER Male gametes oocytes - ANSWER Female gametes testes, epididymis, vas deferens, ejaculatory duct, urethra - ANSWER What is the order of structures through which sperm are produced and ejected?

Which gametes are responsible for sex? correct answer: The sex chromosomes (X or Y) Bipotential Primordium correct answer: Has both mullerian duct and wolffian duct, potential for either male or female development. XX Structure development correct answer: Mullerian duct persists and forms the fallopian tube, uterus, and upper third of the vagina, including the cervix. Wolffian duct regresses due to lack of testosterone. Gondal cortex forms ovary, gondal medulla regresses. XY extra ge...

Why are the testes outside of the body? Correct Answer sperm require cooler temperatures than found in the body cavity in order to develop properly Let's say you have a male patient and they are sick with a high fever.
