Compare and contrast Mendels law of segregation with his law

Compare and contrast Mendel\'s law of segregation with his law of independent assortment. Use examples to illustrate the patterns these laws predict.

Solution

According to Mendel\'s law of segregation he stated that one of the two gene copies present in an organism is distributed to each gamete either the reccessive gene or the dominant gene is past. However with his law of independent assortment he stated that the allele a gamete receives for one gene does not influence the allele received for another gene. So when we compare the mendel\'s law of segregation and independent assortment we can assume that he assumed the allelles would be shared and that the manner in which they would be shared was not known.

This being said from the law of independent assortment he could conclude that if two F1 generations of a particular species were merged the obtained ratio would be 9:3:3:1. This is evident in the case of a pea plant who has dominant Yellow (Y) color skin and Round (R) seeds were merged with a reccessive Green (y) color skin and Wrinkled (r) seeds. The F1 generation produced 4 types of pods which were 3 Yellow and Round pod plant out of which 2 had reccessive allelles in them, another all four dominant allelles and 1 Green wrinkled pod plant.

Now if 2 of these same F1 generation plants were crossed the resultant would be four notable types of plants 1. yellow and wrinkled. 2. yellow and round. 3. green and round and 4. green and wrinkled. Thus proving in other words, the result obtained if each gamete randomly got a Y or y allele, and, in a separate process, also randomly got an R or r allele is (9:3:3:1).
