In lab, we used Benedict's reagent to test for one particular reducing sugar: glucose. Benedict's reagent starts out aqua-blue. As it is heated in the presence of reducing sugars, it turns yellow to orange. The "hotter" the final color of the reagent, the higher the concentration of reducing sugar.

Suppose there are two homologous chromosomes. Each chromosome contains a single mutant allele in different parts of the chromoso
Harlamova29_29 [7]

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

Insect wings may have begun to evolve as lateral extensions of the body that were used as heat dissipaters for thermoregulation.
Mariulka [41]

Exaptation

Explanation:

In this example, the lateral extensions that developed were meant for thermoregulation.

But these became sufficiently large to support gliding through the air and later on were used for flight.

Thus the structure assumed a function for which it was not meant and its original function shifted to a completely different dimension giving rise to modern insect wings. So we can say that this is an example of Exaptation.
