7.L.2.1

Which is a characteristic of asexual reproduction?

• Half of the offspring have learned traits similar to the parents.
• All of the learned traits pass from parents to offspring.
• All of the inherited traits are the same as the parents.
• Half of the inherited traits come from two parents.

A gene mutates in a type of bacteria. When these bacteria reproduce asexually, this mutation can only be inherited by

• different types of bacteria.
• cells in the bacteria that are non-reproductive.
• bacteria cells that are missing the gene.
• direct descendants of the bacteria.

All of the inherited traits that are passed to offspring during asexual reproduction come from a single

• egg
• sperm
• virus
• parent

When an egg and sperm form an embryo, the offspring that is formed will have genetic traits that are

• inherited from only one parent.
• created by the environment.
• passed on from two parents.
• learned from siblings.

Potatoes can reproduce asexually. Each sprout on a parent potato can grow into a new potato plant.
How does the genetic material in the sprout compare to the parent potato?

• The sprout has a random genetic assortment.
• The sprout has twice the genetic material of the parent potato.
• The parent potato has twice the genetic material of the sprout.
• Both the sprout and the parent potato have the same genetic identity.

Which best describes sexual reproduction in all animals?

• Egg and sperm join together.
• Pollen and seed join together.
• Offspring have traits of only one parent.
• Offspring are identical to one parent.

Which of these is the best example of sexual reproduction?

• binary fission
• fragmentation
• budding
• fusing gametes

In animals, female traits are passed down to offspring from

• sperm
• eggs
• seeds
• pollen

A bacterium can reproduce quickly by splitting into two cells. Which of these best describes the genetic make-up of the resulting two cells?

• They have the same amount of genetic material and are identical.
• They have the same amount of genetic material but are not identical.
• They have half the amount of genetic material, which grows in size.
• They have half the amount of genetic material, but then it duplicates itself.

Meiosis is a type of cell division in which germ cells divide to produce haploid cells. Where does meiosis occur?

• brain cells
• bone cells
• muscle cells
• ovary cells
