Explanation / Answer

The present questions represent the simple lab exercise for school students conducted for the demonstration of Mandal law of independent assortment.

Law of independent assortment: Mendel's law of independent assortment states that the alleles of two (or more) different genes get sorted into gametes independently of one another. In other words, the allele a gamete receives for one gene does not influence the allele received for another gene.

Case 4B:

Under this exercise, each partner (boy and girl) have to pick up two Popsicle sticks of yellow and green color of autosome. Each stick represents a chromosome. After that each parent will randomly drop his or her stick on the table. The pair of sticks formed on table represents the chromosome that is passed on to the baby. As green and yellow sticks transfer in baby as they are in parents, it shows the independent assortment.

Case 4 C:

Although Mendel's principle of independent assortment states that alleles of different genes will segregate independently into gametes, in reality, this is not always the case. Sometimes, alleles of certain genes are inherited together, and they do not appear to undergo independent assortment at all. This phenomenon is now known as genetic linkage, and it generally describes an inheritance pattern in which two genes located in close proximity to each other on the same chromosome have a biased association between their alleles. This, in turn, causes these alleles to be inherited together instead of assorting independently. Genetic linkage is a violation of the Mendelian principle of independent assortment.
