Asexual and Sexual Reproduction

​

Asexual reproduction

• Offspring are clones of the parent

• The offspring has the same DNA as the parent

Asexual reproduction

The process used for asexual reproduction is mitosis

.

Benefits:

-Quick

-Reproduction can happen without a mate

.

Disadvantage:

-Lack of genetic diversity

Sexual reproduction

Sexual reproduction involves gametes (example: sperm and egg)

Sexual Reproduction

The process used to make the gametes for sexual reproduction is meiosis.

.

Benefits

• Genetic diversity

• Diversity supports survival of the species

.

Disadvantage

High use of energy and time

Multiple Choice

The process used for asexual reproduction is

• meiosis

• mitosis

Multiple Choice

Offspring that are produced by only one parent are

• genetically diverse

• clones

• gametes

Multiple Choice

Asexual reproduction produces offspring with DNA that is _________ the parent.

• different from

• the same as

Multiple Choice

Sexual reproduction requires two

• gametes

• skin cells

• embryos

Multiple Choice

A benefit of sexual reproduction is

• less energy is used

• greater genetic diversity in the species

• it is more efficient than asexual reproduction

Multiple Choice

A disadvantage of sexual reproduction is that it is

• more time consuming than asexual reproduction

• creates less diversity than asexual reproduction

• uses less energy than asexual reproduction

Multiple Choice

Why is greater genetic diversity important for a species?

• the species is more likely to survive disasters

• the population of the species will never get too large

• there will be less competition with other species

Mitosis

One way cells divide

Multiple Select

Why do cells divide by mitosis? (Check all that are true)

• To make more cells

• To help with growth and repair

• To help make new offspring that are different from the parent

• To help make new offspring that are the same as the parent

Multiple Choice

Before cells can divide, what must be copied?

• mitochondria

• cytoplasm

• DNA

• Cell Wall

Multiple Choice

This image shows chromosomes during Prophase 1. Which of the following correctly describes the process shown?

• segregation of sister chromatids

• condensation and segregation of alleles

• mutationin which the DNA content of the gene is altered

Multiple Choice

Why do we need meiosis?

• To double the number of chromosomes going into sex cells

• To halve the number of chromosomes going into sex cells

• To triple the number of chromosomes going into sex cells

• To not change the number of chromosomes going into sex cells
