The correct option is C Law of independent assortment
A. Law of segregation: Monohybrid cross forms the basis of this law. According to this law, in F2 hybrid, the dominant and recessive characters though remain together for long time but they do not mix with each other and segregate at the time of gametogenesis (gamete formation).
B. Law of multiple factor hypothesis: This hypothesis states that for some traits, multiple genes or factors control the heredity of that particular trait.
C. Law of independent assortment: Dihybrid cross is the basis of this cross. This law states that inheritance of one character is always independent of the inheritance of other character within the same individual. In other words, if the inheritance of more than one character is studied simultaneously, the factors or genes for each character assort out independently of the other factor or gene.
D. Law of dominance: Monohybrid cross forms the basis of this law. According to this law, when a cross is made between two homozygous (pure line) individuals considering contrasting trait of simple character, then the trait that appear in F1 hybrids is called dominant and the other one is called recessive trait.
•Linkage is the inheritance of certain genes as a group because they are present on the same chromosomes. Hence, linked genes do not show independent assortment.
So, the correct answer is 'Law of independent assortment'.
