Let 'C' denote the dominant trait of eye-crossing and 'c' denote the recessive trait of not being able to cross the eyes. The genotype of the father is heterozygous dominant for the trait of eye-crossing. This is denoted by 'Cc'. The mother is homozygous recessive for the trait of eye-crossing, denoted by 'cc'. The mating between the two will result in following genotypes: two of 'Cc' and two of 'cc'. Therefore the probability that the child will be able to cross his or her eyes is 0.5 or 50%.
Answer: The correct answer for the fill in the blank is- Law of independent assortment.
According to the Mendel's law of independent assortment, the allele ( alternative form of a gene that corresponds to a trait) pairs of different genes segregate independent of each other during the process of gamete formation. This means that different traits are transmitted independently from parents to their offspring.
Thus, Law of independent assortment is the right answer.
