BIO 182 Exam 2 Questions with Correct Answers In a simple Mendelian monohybrid cross, true-breeding tall plants are crossed with short plants, and the F1 plants, which are all tall, are allowed to self-pollinate. What fraction of the F2 generation are both tall and heterozygous? a. 1⁄8 b. 1⁄4 c. 1⁄3 d. 2⁄3 e. 1⁄2 - Answer-e. 1⁄2 The phenotype of an individual a. depends at least in part on the genotype. b. is either homozygous or heterozygous. c. determines the genotype...

Bio 202 EXAM 3 QUESTIONS AND CORRECT DETAILED ANSWERS How is recombinant DNA technology used to clone the human GH gene? 1st step! - ANSWER 1. use PCR to obtain the gene (Simply cutting the DNA with restriction enzymes would not be an effective way to isolate a specific gene. The genome would be cut into so many fragments, if you ran a gel it would be a smear! Which fragment is yours? You would need hybridization to isolate your fragment. Wouldn't have much DNA- not like the amo...

BIS 2B Midterm 2 Exam Review With 100% Correct Answers 2023 Mendel - Correct Answer-Augustinian monk and botanist whose experiments in breeding garden peas led to his eventual recognition as founder of the science of genetics () blending model - Correct Answer-Blending model: Offspring are a blend of both parents (i.e. in modern terms, alleles would blend together to form a completely new allele) The characteristics of the blended offspring are passed on to the next generation Variation i...
