Sexual and Asexual Reproduction

Sexual and Asexual Reproduction

Multiple Choice

The new cells formed at the end of cell division are called...

• Parent Cells

• Daughter Cells

• Sister Cells

Multiple Choice

The process of forming offspring from ONE parent is called...

• Sexual Reproduction

• Asexual Reproduction

• Unicellular Reproduction

Diploid

• Diploid = full set of chromosomes

• Chromosomes = smaller chunks of DNA

Diploid in Organisms You Know

• Diploid in dogs = 78 chromosomes

• Diploid in humans = 46 chromosomes

• Diploic in chimpanzees = 48 chromosomes

Why Asexual Reproduction Doesn't Require Sex

A diploid cell creates two new diploid cells - all cells have the full DNA after division.

Multiple Choice

What are smaller chunks of DNA called?

• Nucleus

• Diploid

• Reproduction

• Chromosome

Multiple Choice

If an organism reproduces asexually and the parent cell contains 32 chromosomes, how many chromosomes will the daughter cells have?

• 16

• 32

• 64

How is Sexual Reproduction Different from Asexual Reproduction?

There are 2 divisions

There are 4 daughter cells

The daughter cells are haploid = half the DNA

Diploid vs Haploid

• Diploid = full set of chromosomes

• Haploid = a half set of chromosomes

Haploid in Organisms You Know

• If Diploid in dogs = 78 chromosomes the haploid =

• If Diploid in humans = 46 chromosomes, the haploid =

• Diploic in chimpanzees = 48 chromosomes, the haploid =

Gametes

Haploid cells are called gametes.

In males, they are called sperm.

In females, they are called eggs.

Why does sexual reproduction require sex?

The daughter cells are haploid = half the DNA

Fertilization is needed to combine two haploid cells to make a new diploid cell.

Multiple Choice

Cats have 38 chromosomes in their DNA. How many chromosomes would be in the egg cell of a cat?

• 38

• 19

• 76

• 57

Multiple Choice

Which of the following best describes the result of sexual reproduction?

• Two haploid cells combine to form a diploid cell after fertilization.

• Two diploid cells combine to form one haploid cell after fertilization.

• A haploid and diploid cell combine to form a zygote after fertilization.
