**Probability of Maternal Chromosomes in Gametes**A short-tailed weasel contains a total of 6 chromosomes in its somatic cells. Assuming that crossing over does not occur, what is the probability that a gamete will only contain chromosomes of maternal origin?- **Selected Answer:** a. ❌ 1/6 - **Correct Answer:** b. ✔️ 1/8 **Explanation:**In this scenario, each gamete contains half of the organism’s chromosomes after meiosis. For a somatic cell with 6 chromosomes, there are 3 pairs of homologous chromosomes. Without crossing over, the probability that a gamete will receive only maternal chromosomes follows the formula (1/2)^n, where n is the number of pairs. Therefore, (1/2)^3 = 1/8, making 1/8 the correct probability.

The chances of gamete will only contain chromosome of maternal origin is 1/8 percent
