Question

put these events in order. they explain how a new gene mix in one individual can increase the variety of a whole population.
(2 points)
= crossing - over during meiosis creates a sex cell with a unique gene mix.
= the resulting organism passes this new gene mix to its offspring.
= the populations overall gene variety increases. this improves its ability to adapt.
= the sex cell fuses with another to form a new cell with a genetic change.
= over many generations, the new change spreads through the population.

Explanation:

1. First, crossing - over during meiosis creates a sex cell with a unique gene mix. This is the initial step in generating a new gene combination.
2. Then, the sex cell fuses with another to form a new cell with a genetic change. Fertilization of the unique sex cell leads to a new genetic combination in a cell.
3. Next, the resulting organism passes this new gene mix to its offspring. The organism with the new genetic makeup can pass it on.
4. After that, over many generations, the new change spreads through the population. As the offspring with the new genes reproduce, the trait spreads.
5. Finally, the population's overall gene variety increases. This improves its ability to adapt. The spread of the new gene mix increases the genetic diversity of the population.

Answer:

1. Crossing - over during meiosis creates a sex cell with a unique gene mix.
2. The sex cell fuses with another to form a new cell with a genetic change.
3. The resulting organism passes this new gene mix to its offspring.
4. Over many generations, the new change spreads through the population.
5. The population's overall gene variety increases. This improves its ability to adapt.
