hhhhhhhhhhhhjujj
Head exception if there’s a blindness of the rolled eyes
I found the full exercise on the internet and it ends like this:
"<span>These genes are 30 cM apart on the third chromosome. Explain how this ratio arose." Attached is an image of the cross mentioned above.
Crossing over in the female contributed to the possible existing allele combination |e-ca| that did not exist in the parents genotypes. With this new allele combination, the new possibilities are |</span>♀e-ca/♂e-ca+|, |♀e-ca/♂e+-ca|, |♀e+-ca+/♂e-ca+|, and |♀e+-ca+/<span>♂</span>e+-ca|, leading to the respectively phenotypes ebony, claret, wild, wild. These results correspond to the obtained phenotype ratio.
As continents drift apart, it becomes hard for a population to
mingle freely due to geological separation.
This restricts the gene flow in the once homogenous population hence resulting in the allopatric
speciation of the separated groups of the population. Also, as the continents drift, their climate changes and so does the flora and fauna in the process of
adaptation.
Answer:
My answer to you is that the positive willing to do tests and experiments over and being okay with being wrong if you are.
