Not knowing what the choice of conditions is, I would say that it would be very damp conditions on land, and if the plant photosynthesises it would be good because of 'purer' sunlight. but if show what the choice of conditions are I can give you a more accurate answer (hopefully)
Answer:
Cross overs can lead to formation of chromosome pairs that have no mutant allele.
Explanation:
Cross overs can lead to formation of chromosome pairs that have no mutant allele.
For example -
Suppose "X" is a mutant allele and "x" is a mutant free allele.
Now when two homologous chromosomes contains a single mutant allele in different parts of the chromosome are crossed the following offspring are produced
X x
X XX Xx
x Xx xx
"xx" is a mutant free genotype.
Thus, crossing over can create a single mutation-free chromosome
He inferred that similar changes had happened in the past. Uniformitarianism combines the idea of gradual change over time with Lyell's observations that such changes have occurred at a constant rate and are ongoing.
