#1. Which of the following statements correctly describes the Law of Independent Assortment? Select one:a). Non-allelic genes do not affect each other if they are located on separate chromosomes.b). A large Punnett square can be used to predict the outcome of a parental cross involving two traits.c). The dominant allele is represented with an uppercase letter and the recessive allele is represented with a lowercase letter.d). Sometimes all alleles lack dominance, which leads to a blending of traits.

Answer: A
"when two or more characteristics are inherited, individual hereditary factors (genes) assort independently during gamete production, giving different traits an equal opportunity of occurring together." -dictionary.com
if the genes are located too close to each other on the chromosome, they will not assort independantly; sometimes they'll assort together!

I would say the answer is B.
Option A states the effects of non-allelic genes which cause an expression of character through their interaction. This happens when two homologs are very similar but do not alleles. These alleles will interact through crossing over, not independant assortment.
Option C refers to representations of alleles, not independant assortment.
Option D refers to incompletele dominance, not independant assortment.
Option B states that we can use a Punnett square to predict frequencies, this is true when all genetic combinations are equall likely to occur. In independant assortment maternal and paternal chromosomes align randomly along the metaphase plate allwowing each combination an equally likely chance of occuring. This option is true.
