Question
**Statement:** The closer genes are together, the more they recombine **Options:** - a) True - b) False **Explanation:** This statement explores the concept of genetic recombination. In genetics, the physical distance between genes on a chromosome can influence their likelihood of recombining during meiosis. If genes are closer together, they are less likely to recombine due to lower chances of crossover events occurring between them. Therefore, the statement is generally considered false. **Discussion:** Recombination refers to the exchange of genetic material between homologous chromosomes during meiosis, leading to genetic variation in offspring. Genes that are physically closer on a chromosome are less likely to be separated by recombination, whereas genes farther apart have a higher chance of being recombined. This is an important concept in understanding genetic linkage and mapping.

**First Cell Image Description:** The image depicts a cell in a circular shape with a dark purple background. Inside the cell, there are distinct dark lines (chromosomes) aligned at the center. Spindle fibers are extending from opposite poles towards the center, indicating the cell is structured for division. **Question:** This cell is in what stage? - [ ] Interphase - [ ] Prophase - [X] Metaphase - [ ] Anaphase - [ ] Telophase **Second Cell Image Description:** The image shows a blue circular cell with a distinct dark area, likely representing the nucleus. Chromosomes and spindle fibers are beginning to appear, and centrosomes are moving apart, which is characteristic of early cell division phases. **Question:** This cell is in what stage? - [X] Interphase - [ ] Prophase - [ ] Metaphase - [ ] Anaphase - [ ] Telophase

Expert Solution
Step 1

Genes that are sufficiently close together on a chromosome will tend to "stick together," and the versions (alleles) of those genes that are together on a chromosome will tend to be inherited as a pair more often than not. This phenomenon is called genetic linkage.

The closer two genes were to one another on a chromosome, the greater their chance of being inherited together. In contrast, genes located farther away from one another on the same chromosome were more likely to be separated during recombination.
