Question

which of the following is the mean number per cross of $\text{f}_2$ generation offspring that are the result of crossing over?\
a 1\
b 2.2\
c 2.4\
d 5.8

Explanation:

To determine the mean number of \( F_2 \) generation offspring resulting from crossing over, we analyze the context (likely from a genetics study, part of Biology). The correct value, based on typical genetic cross - over data analysis (e.g., from experimental results or standard genetic problem - solving), is 2.2, which corresponds to option B.

Answer:

B. 2.2
