Sexual vs Asexual Reproduction

A technique used to reproduce plants is shown in the diagram. This technique is a form of

• gene manipulation

• sexual reproduction

• asexual reproduction

• gamete production

Which process produces the most variation within a species?

• asexual reproduction

• sexual reproduction

• mitosis

• cloning

1. Which process occurs in sexual reproduction?

• fission

• budding

• vegetative propagation

• fusion of gametes

1. Potato plants reproduce both sexually and asexually. Depending on the desired outcome, potato growers use both types of reproduction. A grower would most likely want the potato plants to reproduce asexually when 

• 1. selectively breeding new potato varieties 

• 1. there is a disease affecting similar potatoes growing in the area 

• 1. environmental conditions in the area are changing 

• 1. potatoes with the same traits are desired

The diagram illustrates 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

Models A and B illustrate two different methods of reproduction. Which statement best describes the offspring that result from these methods?

• Both models A and B produce offspring that have fewer chromosomes than the parent cells.

• Both models A and B result in offspring that have more chromosomes than the parent cells.

• 1. Model A produces offspring with genetic information different from the parent. Model B produces offspring that are genetically identical to the parents. 

• Model A produces offspring with identical genetic information to the parent cells. Model B produces offspring that are genetically different from the parent cells.

1. Strawberries can reproduce by means of runners, which are stems that grow 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

• it was produced asexually

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

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

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

• All genetic material comes from one parent.

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

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

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

The least genetic variation will probably be found in the offspring of organisms that reproduce using

• internal fertilization to produce an embryo

• fusion of eggs and sperm to produce zygotes

• 1. meiosis to produce gametes

• mitosis to produce a larger population
