After telophase I of meiosis, the chromosomal makeup of each daughter cell is

haploid, & the chromosomes are each composed of two chromatids.

diploid, and the chromosomes are each composed of two chromatids.

haploid, and the chromosomes are each composed of a single chromatid.

How do cells at the completion of meiosis compare with cells that have replicated their DNA and are just about to begin meiosis?

half the number of chromosomes and one-fourth the amount of DNA.

half the amount of cytoplasm and twice the amount of DNA.

half the number of chromosomes and half the amount of DNA.

same number of chromosomes and half the amount of DNA.

In mitosis, how does the number of chromosomes in a daughter cell compare to the number of chromosomes in a parent cell?

The daughter cell has the exact same number of chromosomes.

The daughter cell has 1/2 the number of chromosomes.

The daughter cell has twice with number of chromosomes.

The daughter cell has 1/4 the number of chromosomes.

How does a sperm or egg cell differ from all other cells in your body?

Sperm and egg cells contain only 1/2 the number of chromosomes as the other cells.

Sperm and egg cells contain twice the number of chromosomes as the other cells.

Sperm and egg cells reproduce through mitosis; the other cell's don't.

Sperm and egg cells contain no chromosomes.

In frogs there are 26 chromosomes in a fertilized egg. Which best describes how many chromosomes are in the egg and sperm cells before fertilization?

13 chromosomes in the egg cell and 13 chromosomes in the sperm cell

26 chromosomes in the egg cell and 26 chromosomes in the sperm cell

52 chromosomes in the egg cell and 52 chromosomes in the sperm cell

If an organism reproduces asexually, as in budding, its offspring will most likely be:

genetically identical to the parent

genetically different from each other.

produced from specialized cells known as egg and sperm.

produced as a result of fertilization.

How do mitosis and meiosis differ?

Mitosis produces 2 identical cells, while meiosis produces 4 different cells.

Meiosis produces 2 identical cells, while mitosis produces 4 identical cells.

Mitosis produces 4 different cells, while meiosis produces 2 identical cells.

Meiosis produces only 1 cell, while mitosis produces many.

Mom and dad each gave 30 chromosomes.

Mom and dad each gave 60 chromosomes.

If the calf looks more like the mom, she gave 40 chromosomes.

If the calf looks more like the dad, he gave 40 chromosomes.
