Which Mendelian idea is depicted by a cross in which the F1 generation resembles both the parents
Among the following characters which one was not considered by Mendel in his experimentation pea?
Assertion: When the two genes in a dihybrid cross are situated on the same chromosome, the proportion of parental gene combinations is much higher than the nonparental type.
Reason: Higher parental gene combinations can be attributed to crossing over between two genes.
According to the evolutionary theory, formation of a new species is generally due to
