• sister cells

• aunt cells

• mother cells

• daughter cells

Multiple Choice

During _____________________chromosomes begin to uncoil, and two new identical nuclei form

• prophase

• metaphase

• anaphase

• telophase

Multiple Choice

During __________________ sister chromatids in each duplicated chromosome separate and are pulled in opposite directions by the spindle fibers.

Multiple Choice

Sexual reproduction increases genetic ____________ because it involves 2 parents and 2 sets of chromosomes.

• distribution

• similarity

• variation (variety)

• clones

Multiple Choice

Meiosis is sexual reproduction because it creates

• diverse daughter cells

• identical daughter cells

• no other cells

• only 1 daughter cell

Multiple Choice

Multiple Choice

A benefit of asexual reproduction is that it is ________.

• faster than sexual and requires only one parent

• slower than sexual and requires only one parent

• produces many genetic variations

• causes traits from both parents to be inherited.

Multiple Choice

Plants can reproduce-

• both sexually and asexually

• only asexually

• only sexually

• plants do not reproduce
