Genetic linkage is the tendency of alleles that are close together. The recombination frequency will be 50% when two genes are located on different chromosomes that are tightly linked to each other.

Which of the following statements is not true about genes that show 50...
Explanation:
The correct answer is option A: The genes are tightly linked.
Recombination Frequency:
Recombination frequency refers to the likelihood of two genes on the same chromosome separating and undergoing recombination during meiosis. It is a measure of the distance between two genes on a chromosome. A recombination frequency of 50% indicates that the genes are likely to segregate independently during meiosis, meaning they are not tightly linked.
Explanation of Each Statement:
a) The genes are tightly linked:
This statement is not true. If the genes show a 50% recombination frequency, it means they are not tightly linked. Tightly linked genes would show a recombination frequency close to zero, indicating that they rarely separate during meiosis.
b) The genes show independent assortment:
This statement is true. Genes that show a 50% recombination frequency are likely to undergo independent assortment during meiosis. This means that the genes segregate independently and are not inherited together as a unit.
c) If the genes are present on the same chromosome, they undergo more than one crossover in every meiosis:
This statement is not necessarily true. The recombination frequency of 50% indicates that the genes undergo at least one crossover per meiosis. However, it does not specify the exact number of crossovers. Multiple crossovers can occur, but it is not a requirement for a 50% recombination frequency.
d) The genes may be on different chromosomes:
This statement is true. Genes that show a 50% recombination frequency can be located on different chromosomes. In this case, the genes segregate independently during meiosis due to the random alignment and separation of homologous chromosomes.
Conclusion:
Among the given options, the statement that is not true about genes that show a 50% recombination frequency is option A: The genes are tightly linked. These genes are not tightly linked and are likely to undergo independent assortment during meiosis.
The correct answer is option A: The genes are tightly linked.
