Answer:
Explanation:
The observed frequency of the double crossovers (DCOs) is 20/1000, or 0.02. If there is no interference then this will be the same as the expected, which is just the product of the single crossover frequencies, that is, SCO frequency (a-b) x SCO freq. (b-c) = 0.02.
(a) Any combination of map distances whose product (a-b) x (b-c) = 0.02 is possible. However, three are most likely:
a 20 mu b 10 mu c
a 10 mu b 20 mu c
a 14.14 mu b 14.14 mu c
(b) The distances would be exactly the same.
(c) The expected number of DCO progeny would be 17.
The level most commonly meant by the term biodiversity is the species level.
Mutation can be both beneficial and harmful.
A very common beneficial mutation is camouflage and natural selection. The organism will acquire the change and pass it on to their offspring.
A harmful mutation can be diseases or a common harmful mutation, Down syndrome. Which gives a person an extra chromosome.
