Answer:

Step-by-step explanation:

To determine the order of the genes on the chromosome, we take recombination frequencies between the genes. Recombination frequency represents the likelihood of a crossover event occurring between two genes during meiosis.

Let's start by organizing the given recombination frequencies:

a,c: 10%

a,d: 30%

b,c: 24%

b,d: 16%

To determine the gene order, we need to identify the highest recombination frequency and use it as a reference point. In this case, the highest recombination frequency is between genes a and d, which is 30%. Therefore, we can assume that a crossover event occurs between genes a and d most frequently during meiosis.

Based on this information, we can establish the following gene order:

a---(10%)---c---(30%)---d

Now, we need to consider the remaining genes, b and c. Since the recombination frequency between b and d is 16%, and the recombination frequency between b and c is 24%, we can conclude that the gene order is as follows:

a---(10%)---c---(24%)---b---(16%)---d

Therefore, the order of the genes on the chromosome is a, c, b, and d
