Question
Consider a cell that has three pairs of chromosomes. What are the chances that a gamete produced from this cell will contain only maternal chromosomes?Multiple Choice1/121/81/41/61/2
Solution
The chance that a gamete produced from this cell will contain only maternal chromosomes is 1/8.
Here's why:
-
For each pair of chromosomes, there are two possibilities: the gamete could receive either the maternal chromosome or the paternal chromosome.
-
Since there are three pairs of chromosomes, the total number of possible combinations is 2^3 = 8.
-
Only one of these combinations contains only maternal chromosomes.
-
Therefore, the probability is 1 out of 8, or 1/8.
