Mendel's monohybrid results served as the basis for all but one of his postulates. part a part complete which postulate was not based on these results? which postulate was not based on these results? when two independent events occur simultaneously, the probability of the two outcomes occurring in combination is equal to the product of their individual probabilities of occurrence. during the formation of gametes, the paired unit factors separate, or segregate, randomly so that each gamete receives one or the other with equal likelihood. genetic characters are controlled by unit factors existing in pairs in individual organisms. when two unlike unit factors responsible for a single character are present in a single individual, one unit factor is dominant to the other, which is said to be recessive. submitprevious answers correct part b why? why? during the mendels experiments, the binomial theorem had not been yet developed. independent assortment cannot be demonstrated by a monohybrid cross because two gene pairs must be involved to do so. independent assortment cannot be demonstrated by a cross because two gene pairs may influence the expression of each other. submitrequest answer provide feedback next correct. no additional followup.
