Reproduction and Chromosomes

What type of reproduction takes place when one parent organism produces offspring that are identical to the parent?

• meiosis

• sexual reproduction

• asexual reproduction

• fertilization

Which of the following is a disadvantage of asexual reproduction?

• All organisms have genetic variation

• Parents produces identical off spring which is not suitable for survival in a changing environment

• Finding a mate is not needed

• It can produce a lot of offspring

What do you call the type of reproduction in which the genetic materials from two different cells combine, producing an offspring?

• pollination

• sexual reproduction

• fertilization

• asexual reproduction

What is the correct name for a sex cell?

• The noise

• Gamete

• Ovary

• Sperm

What do you call the female sex cell?

• egg cell

• sperm cell

• diploid

• haploid

What do you call the cell that forms from fertilization?

• fertilized egg

• sperm cell

• zygote

• egg cell

Hydra produce offspring by growing the new individual on the body of the parent. This is an example of...

• budding.

• fission.

• regeneration.

• tubers.

Which statement describes why genetic variation is beneficial to populations of organisms?

• individuals look different from one another

• only one parent is needed to produce offspring

• populations of the organism increase more rapidly

• species can better survive environmental changes

What is an advantage of sexual reproduction?

• Allows genetic variation
• Only needs one parent
• Happens very quickly
• Offspring are exact copies of parent

How much genetic material is provided by the parents in sexual reproduction?

• 0% from each

• 25% from each

• 50% from each

• 100% from each
