3 Mendelian Laws of Inheritance - Fundamentals of Genetics
Mendel’s Laws of Inheritance
How Mendel began his work
Law of Dominance
Hybrids show Dominant trait (Phenotype)
Law of Segregation
Each allele retain itself distinct identity even though they remain together
When dominant AA and recessive aa is crossed, the percentage ratio of the hybrid showing the parental genotypes is
(A) 0% (B) 25% (C) 50% (D) 75%
Which cross would produce phenotypic ratios that would illustrate the Law of Dominance?
How many gametes would be formed from Aa Bb Cc?
How many gametes would be formed from Aa Bb cc?
Law of Independent Assortment pendent Assortment
‘when two pairs of traits are combined in a hybrid, segregation of one pair
of characters is independent of the other pair of characters’
How many different types of phenotypes would be formed from a cross of RrYy x RrYy?
Assuming complete dominance, what is the phenotypic ratio of the offspring of the cross
(a) 1:1 (b) 3:1(c) 1:1:1:1(d) 9:3:3:1
