sp2606 [1]

Linkage refers to the tendency of inhertance of the DNA sequences that are close together on a chromosome during the meiosis of sexual reproduction. It can be measured by the recombination frequency.

Recombination frequency describes the proportion of recombinant offsrpring produced in a genetic cross between two organisms. It is the frequency with which a single chromosomal cross over takesplace between two genes during the process of meiosis. Recombination frequency (RF) is given by

RF= Recombinants /total offspring  x 100.

In the above example, the number of recombinant offspring is 20 and the total offspring is 400. By substituting these values,

RF= 20/400 x100

= 5.

The recombination frequency for the above cross is 5.

Some students are performing a hydrobiology project on a creek. They obtained the GPP value as 7 mg/l and the R value as 3 mg/l.
mezya [45]
Ayo i think the answer is B, 10 mg/l. bc you would label the respiration rate as R, we come up with a neat little formula: NPP = GPP - R. hope this helps, have an amazing day :)
