Gametogenesis
The process that produces reproductive cells
What is gametogenesis?
The type of cell division involved in gametogenesis.
What is meiosis?
The number of chromosomes in a normal human body cell.
What is 46?
The process of producing sperm.
What is spermatogenesis?
One major reason gametogenesis is important.
What is sexual reproduction?
The male and female reproductive cells.
What are gametes?
The reduction of chromosome number from 46 to 23 is an example of this.
What is reduction division?
The number of chromosomes in a normal human gamete.
What is 23?
The process of producing ova.
What is oogenesis?
A benefit of genetic variation produced during meiosis
What is increased ability to adapt to environmental changes?
The organs where gametogenesis occurs.
What are the testes and ovaries?
The exchange of DNA between chromosomes that creates genetic variation.
What is crossing over?
The number of chromosomes contributed by the sperm during fertilisation.
What are 23 chromosomes?
The number of functional sperm produced from one primary spermatocyte.
What are four functional sperm?
The condition that can occur when chromosomes fail to separate properly.
What is nondisjunction?
The process that allows gametes to have half the normal chromosome number.
What is meiosis?
The random arrangement and separation of chromosome pairs that creates different combinations.
What is independent assortment?
The total number of chromosomes in a normal human zygote.
What are 46 chromosomes?
The number of functional ova produced from one primary oocyte.
What is one functional ovum?
Radiation, chemicals, extreme temperatures, illness or hormonal disruption
What are factors that negatively affect developing gametes?
