Genetics Unit Review Part 1: 7.L.2.1

Which statement best compares the phenotype of the offspring with the phenotype of the parent organism if reproduction occurs by mitosis?

• The phenotype of the offspring is never the same as the phenotype of the parent organism.

• The phenotype of the offspring is always the same as the phenotype of the parent organism.

• The phenotype of the offspring is the same as the phenotype of the parent organism one-half of the time.

• The phenotype of the offspring is the same as the phenotype of the parent organism one-fourth of the time.

Which statement best compares meiosis with mitosis?

• Both ae forms of sexual reproduction.

• Both are forms of asexual reproduction.

• Meiosis reduces the number of chromosomes in cells, while mitosis conserves the number of chromosomes.

• Meiosis conserves the number of chromosomes in cells, while mitosis reduces the number of chromosomes.

Which statement describes asexual reproduction?

• The offspring receive genes from two different parent organisms.

• The offspring receive all their genes from a single parent organism.

• The offspring produce half their genes and receive the other half from a single parent organism.

• The offspring produce half their genes and receive the other half from two different parent organisms.

How do organisms that reproduce asexually develop genetic diversity?

• through mitosis

• through meiosis

• through budding

• through mutations

Which is an advantage of sexual reproduction within a species?

• genetic variation

• high mutation rate

• rapid reproductive rate

• genetically identical offspring

A new life-form is found with 10 chromosomes in each of its body cells. The life-form reproduces sexually. How many chromosomes will most likely be passed on to the offspring from one parent?

• 0 chromosomes

• 5 chromosomes

• 10 chromosomes

• 20 chromosomes

How many parents are involved in the production of identical daughter cells during asexual reproduction?

• one

• two

• three

• four

Which process allows organisms to produce new cells as they grow and develop?

• budding

• fertilization

• meiosis

• mitosis

An organism with 28 chromosomes undergoes cell division. The resulting cell contains 28 chromosomes. Which type of cell division occurred?

• haploid

• meiosis

• mitosis

• sexual

How are cells produced through mitosis and meiosis different?

• They have different cell shapes

• They have different numbers of chromosomes.

• They have different levels of activity in the ribosomes.

• They have different components in the cell membrane.
