<span>The correct answer to this question is this:
In stage of prophase crossing-over (the physical exchange of chromosome parts) occurs. Crossing-over is the process that can give rise to genetic recombination.
In mataphase stage Independent assortment is occour and it refers to the random arrangement of pairs of chromosomes. The diagram below shows four possible arrangements of chromosomes during metaphase 1 from an individual that has 6 total chromosomes. Suppose that the pink chromosomes are those that the individual inherited from its mother and the blue colored ones were inherited from its father. For each chromosome pair, the chromosome that is on the left (maternal or paternal) is determined randomly. As can be seen, there are several alignment possibilities.</span>

Answer:
B) Nutrient B only
Explanation:
According to the given information, A, B, and C are required for the normal growth of the organism. The mutant strain has mutated gene A and therefore, can not convert the A into B. However, the given mutation strain is able to convert B into C. If the mutant strain is supplemented with "B", it would be able to form C. In absence of "B" in the medium, the strain would not be able to form both B and C. Therefore, presence of "B" is required in the medium for the given mutant strain.
Answer:
Explanation:
Crossing over is a complex mechanism which allows the exchange of the DNA sequence during meiosis.
Crossing over serves many purposes:
1. form genetically different daughter cells from parents.
2. leads to genetic diversity
3. leads to variation in the organism which proves useful.
The crossing over does not take place in the mitosis type of cell division which produces genetically similar daughter cells.
