Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following describes how alleles will be inherited without influencing each other?
A
Law of Independent Assortment
B
Law of Segregation
C
Law of Fertilization
D
Law of Mitosis
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -Law of segregation: During gamete formation, the alleles for each gene segregate from each other so that each gamete carries only one allele for each gene. Law of independent assortment: Genes for different traits can segregate independently during the formation of gametes.

Detailed explanation-3: -Example of Law of Independent Assortment Two-hybrid rabbits are crossed. Both the rabbits have a genotype BbGg. Before breeding each rabbit produced gametes. During this, the alleles are separated and the copy of each chromosome is assigned to different gamete.

Detailed explanation-4: -Independent assortment states that an allele for each gene is passed on independently from alleles of other genes. Likewise, segregation states that the two alleles for each gene are separated and only one is passed on.

Detailed explanation-5: –According to the law of independent assortment, ”In a dihybrid cross, segregation of one pair of alleles or one pair of characters is independent of another pair of alleles or another pair of characters.”-He took one pea plant that was having the seeds of yellow color with a round shape(YYRR).
