The model shows the process of meiosis.

Question

Use the model to describe how genetic continuity is preserved through meiosis.
A.

Cell 7 shows different colored chromosomes than Cell 8. When meiosis is a part of reproduction, none of the offspring will have similar DNA.

B.

Cell 2 shows twice as many chromosomes as Cell 3. When meiosis is a part of reproduction, the offspring inherits twice as much DNA as its parent.

C.

Cell 6 shows different colored chromatids than Cell 1. When meiosis is a part of reproduction, the offspring's DNA will be entirely different from the parent's DNA.

D.

Cell 5 shows half the number of chromatids present in Cell 1. When meiosis is a part of reproduction, half of the offspring's DNA will come from each parent

Answer 1

The correct option that describes how genetic continuity is preserved through meiosis is:

D. Cell 5 shows half the number of chromatids present in Cell 1. When meiosis is a part of reproduction, half of the offspring's DNA will come from each parent.

This statement accurately reflects how meiosis reduces the chromosome number by half, resulting in gametes (sperm and eggs) that carry only one set of chromosomes. When fertilization occurs, the offspring receives half of its genetic material from each parent, thus maintaining genetic continuity while also introducing genetic diversity.
