Which statement explains why the recombination frequency between two genes is always less than 50%? A) recombination cannot be more than 50% because chromosome are only 50 map units in lengthB) F1gametes always have 50% of their alleles from each parental gameteC) The genotype of the F1 gametes will always be 50% parental games and 50% recombinant gametesD) genes with a recombination frequency near 50% are unlinked and have an equal likelihood of being inherited together or separately

Jerome · Answer 1

Option (D).

Explanation:

Recombination frequency nay be defined as the the frequency of crossover of a single chromosome during meiosis. The maxiumum recombination frequency is 50%.

Genes that has recombination frequency nearly equal to 50% are considered as unlinked genes. Unlinked genes cannot undergo the recombination process and may have equal chances to inherit together or can inherit separately in the next generation.

Thus, the correct answer is option (D).
