Asexual and Sexual Reproduction

Strawberries can reproduce by means of runners, which are stems that run horizontally along the ground. At the region of the runner that touches the ground, a new plant develops. The new plant is genetically identical to the parent because

• it was produced sexually

• nuclei traveled to the new plant through the runner to fertilize it

• it was produced asexually

• there were no other strawberry plants in the area to provide fertilization

The diagram on the left shows a yeast cell in the process of budding, a form of asexual reproduction. Which statement best describes the outcome of this process?

• The bud will develop into a zygote.

• The two cells that result will each contain half the species number of chromosomes.

• The two cells that result will each have identical DNA.

• The bud wills start to divide by the process of meiotic cell division.

The diagram on the let shows asexual reproduction in yeast. Yeast produce offspring that usually have

• genes that are different from those of the parent

• genes that are identical to those of the parent

• half of the genetic information of the parent

• organelles that are not found in the parent

A particular species of shark normally reproduces sexually. In captivity, it was found that a female could also reproduce asexually. One negative result of asexual reproduction is

• increased number of males produced

• decreased genetic variability/diversity within the species

• decreased number of eggs used

• increased number of mutations

How does the type of reproduction shown in method A differ from the type of reproduction shown in method B?

• Method A illustrates sexual reproduction, whereas method B illustrates sexual reproduction.

• Offspring produced by method A will be genetically different, whereas offspring in method B are genetically alike.

• Offspring in method A are genetically identical to parents, but offspring in method B are genetically different from parents.

• Offspring in method A are single-celled organisms, where offspring in method B are multicellular.

When a planarian (a type of worm) is cut in half, each half usually grows back into a complete worm over time. This situation most closely resembles

• asexual reproduction in which a mutation has occurred

• asexual reproduction of a single-celled organism

• sexual reproduction in which each half represents one parent

• sexual reproduction of a single-celled organism

A pattern of reproduction and growth in a one-celled organism is shown on the left. Which statement best describes this pattern of inheritance?

• All genetic material comes from one parent.

• Only some of the genetic material comes from one parent.

• The size of the parent determines the amount of genetic material.

• The size of the parent determines the source of the genetic material.
