Chromosomes exchange genetic material in step 3.
<h3><u>Explanation</u>:</h3>
The meiosis is the type of cell division that takes place for gametogenesis. The meiosis has two phases - meiosis I and meiosis II.
The meiosis I has the events like crossing over and independent assortment which leads to the mixing of genes between homologous chromosome pairs and separation of homologous chromosome pairs. So the two cells that are produced from the meiosis I are genetically different. The step 3 shows the crossing over of prophase 1 of meiosis I. So, it shows the genetic difference between the offsprings and leads to genetic variation.
Thymine and cytosine are classified as "Pyrimidines" and have one ring of carbon and nitrogen atoms for each base.

It is fundamental to seek the balance between transport and consumption of oxygen to the tissues, with the inversion of the anaerobiosis of the tissues
Answer:
The correct answer is - yes, variation can be advantageous.
Explanation:
The population of the lima beans that are able to adapt to changes and include these variations in their population will lead individuals are able to survive and reproduce to increase their numbers in changing environments. The igher the variability in the population is, the higher the chances of the to be advantageous for their survival and increase their population.
Thus, the correct answer is - yes.
