Question

Which one of the following is not one of Mendel's laws?
A. Law of Dominance
B. Law of Segregation
C. Law for incomplete dominance
D. Law of independent assortment

Answer 1

Gregor Johann Mendel was a scientist regarded as the father and founder of genetics. Mendel conducted several research on the pea plant during 1856 and 1863. He examined the results of the experiments and deducted a number of observations. Therefore the rules of inheritance or the laws of Mendel's have come into being.

Complete answer:
Although Mendel's studies built the groundwork, it would be the German botanist Carl Correns who has been credited with the eventual identification of incomplete dominance. In the early 1900s, Correns performed similar experiments at four o'clock plants. In his research, Correns noticed a mixture of colors in flower petals. This brought him to the conclusion that perhaps the ratio of genotype 1:2:1 prevailed and each genotype does have its own phenotype. On the other hand, it allowed the heterozygous to display both alleles instead of a dominant allele, as though it were a dominant one, as Mendel had found. An example of incomplete dominance is for instance an infant born to a straight-haired parent and a curly-haired parent will usually have wavy hair, or slightly curly hair, due to the presence of both curly and straight alleles. Incomplete dominance can be seen in many other physical features, like skin color, height, vocal pitch, etc.
So, the correct answer is option C.

Note: Carl Correns is recognized for his independent exploration of the principles of heredity as well as for his discovery of non-Mendelian origins, like the cytoplasmic inheritance. It is considered to occur in which neither one of these gene alleles is totally dominant over the other and the hybrid is independent between both the parents.
