Answer:
D. Genes A and B are likely to stay together, but they are more likely to become separated from gene C since a crossover is more likely to occur in the longer space between them.
Explanation:
Cross over between homologous chromosomes occurs during meiosis I. A synapsis is formed and non sister chromatids exchange genetic material between each other. If gene A and gene B are close to each other on a chromosome, they most likely will show linkage. During cross over these genes will have more probability to get inherited together from the parent and hence offspring with parental combination will be more in number. Since gene C is farther away from the two genes, it will show normal cross over and recombination. Offspring produced will have almost equal parental and new combination.
