Which of the following is a true statement regarding genetic maps and cytological maps?
A) The genetic distance and physical distance on cytological maps are not always uniform
B) Genetic maps and cytological maps are colinear
C) Genetic distances are not proportional to cytological distances
D) All of these are true
E) None of these are true

Question

Quizplus · Accepted Answer

Genetic maps and cytological maps often show a lack of uniformity between genetic distance and physical distance, indicating that genetic distances (measured in centimorgans) do not always correlate directly with physical distances (measured in base pairs or location on a chromosome). This discrepancy can result from various factors, including recombination frequency. Additionally, while genetic maps and cytological maps aim to represent the same genome regions, their colinearity can be disrupted by structural variations or differences in mapping techniques, further supporting the statement that all provided options are true.
