AP BIOLOGY

Detailed explanation-1: -There are two types of reproduction: asexual and sexual reproduction. Though asexual reproduction is faster and more energy efficient, sexual reproduction better promotes genetic diversity through new combinations of alleles during meiosis and fertilization.

Detailed explanation-2: -Binary fission starts with a single cell that copies its DNA and then splits into two identical cells. This is a very fast and efficient way for bacteria and similar types of cells to create offspring.

Detailed explanation-3: -Scientists who study how organisms reproduce know that asexual reproduction is more efficient-for one thing, it’s about twice as fast as sexual reproduction, since every offspring can produce more.

Detailed explanation-4: -Asexual reproduction can be very rapid. This is an advantage for many organisms. It allows them to crowd out other organisms that reproduce more slowly. Bacteria, for example, may divide several times per hour.

Detailed explanation-5: -Asexual reproduction is a mode of reproduction in which a new offspring is produced by a single parent. The new individuals produced are genetically and physically identical to each other, i.e., they are the clones of their parents. Asexual reproduction is observed in both multicellular and unicellular organisms.
