Plz ans q 12
Dear student,
The first two statements are true because Natural selection is a major factor in the change in allele frequency and crossing over leads to the inducement of new characters. On the other hand option, c and option d is wrong because option c states Lamarck law but it is not the major factor. and in option d directional selection refers to a shift in phenotype towards extreme which is not justified by the statement.
Hope it helps,
Regards.
