Suppose there are two homologous chromosomes. Each chromosome contains a single mutant allele in different parts of the chromosome. How can crossovers be beneficial in this situation? (Hint: How can you create a single, mutation-free chromosome?) I NEED HELP

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

b because they naturally adapt to their environment plz mark brainliest

the atmospheric gas that forms a mild acid when dissolved in water is called carbon dioxide. the correct answer is a. 2.) chemical weathering would cause an inscription on a marble headstone to become harder and harder to read over time.
