The law of independent assortment allows for genetic recombination. The following equation can be used to determine the total number of possible genotype combinations for any particular number of genes: 2g = Number of possible genotype combinations (where g is the number of genes) 1 gene: 21 = 2 genotypes […]

Some proponents of creation science draw upon several areas of inquiry including geology and biology to support their claims that the Earth and the life on it were created between 6000-10,000 years ago. For example, they point to continental drift and the Grand Canyon as evidence for the great flood […]

In a generalized transduction experiment, phages are collected from an E. coli donor strain of genotype cys+ leu+ thr+ and used to transduce a recipient of genotype cys- leu- thr-. Initially the treated recipient populations placed on a minimsl medium with leucine and threonine. Many colonies are obtained. a) What […]
