Reproduction and Genetic Diversity Quiz

#1

Which process involves the formation of haploid gametes?

Meiosis
Explanation

Meiosis is the cell division process that produces haploid gametes, ensuring genetic diversity.

#2

During which phase of the menstrual cycle does ovulation occur?

Ovulatory phase
Explanation

Ovulation occurs during the ovulatory phase of the menstrual cycle, releasing an egg for potential fertilization.

#3

What is the term for the process of cell division that produces gametes?

Meiosis
Explanation

Meiosis is the process of cell division specifically dedicated to producing gametes, ensuring genetic diversity in sexual reproduction.

#4

What is the purpose of the SRY gene in humans?

Determines sex development
Explanation

The SRY gene in humans determines the development of male sex characteristics.

#5

During oogenesis, when does meiosis II in the egg cell complete?

After fertilization
Explanation

Meiosis II in the egg cell during oogenesis completes after fertilization, contributing to genetic diversity.

#6

What is the role of DNA in the process of reproduction?

Carries genetic information
Explanation

DNA carries the genetic information that is passed on to offspring during the process of reproduction.

#7

Which of the following is a reproductive structure in plants?

Stamen
Explanation

Stamen is a male reproductive structure in plants, producing pollen for fertilization.

#8

What is the primary function of the testes in the male reproductive system?

Produce sperm
Explanation

The testes produce sperm, the male gametes, and are essential for male reproductive function.

#9

Which structure connects the uterus to the outside of the body?

Cervix
Explanation

The cervix is the structure that connects the uterus to the outside of the female body, allowing the passage of menstrual blood and facilitating childbirth.

#10

In which part of the female reproductive system does fertilization typically occur?

Fallopian tube
Explanation

Fertilization typically occurs in the fallopian tube, where the egg and sperm meet.

#11

What is the significance of genetic variation in a population?

Enhances survival and adaptation
Explanation

Genetic variation in a population enhances the ability to adapt and survive in changing environments.

#12

In sexual reproduction, what is the significance of genetic recombination?

Generates genetic diversity
Explanation

Genetic recombination during sexual reproduction generates diversity among offspring, enhancing adaptability.

#13

What is the term for a cell formed by the union of two gametes during fertilization?

Zygote
Explanation

A zygote is formed by the fusion of two gametes during fertilization, initiating the development of a new organism.

#14

What is the purpose of meiosis in the context of sexual reproduction?

Produce gametes with half the chromosome number
Explanation

Meiosis ensures the production of haploid gametes, each with half the chromosome number of the parent cell.

#15

In humans, what is the approximate gestation period for a full-term pregnancy?

9 months
Explanation

A full-term pregnancy in humans typically lasts approximately 9 months from conception to childbirth.

#16

What is the purpose of the placenta during pregnancy?

Exchanges nutrients and waste between mother and fetus
Explanation

The placenta facilitates the exchange of nutrients and waste between the mother and fetus during pregnancy.

#17

Which of the following is a method of asexual reproduction in plants?

Budding
Explanation

Budding is a method of asexual reproduction in plants where a new individual develops from a bud or outgrowth.
