BIOL 111 Final LATEST ACTUAL EXAM QUESTIONS AND CORRECT ANSWERS (VERIFIED ANSWERS) |ALREADY GRADED A+ Mendel crossed pea plants that had inflated pods with those that had constricted pods and then allowed those offspring to selfpollinated to produce an F2 generation. When he counted the offspring in the F2, 882 had inflated pods and 229 had constricted pods (1182 total). The allele for constricted pods has what relationship to the allele for inflated pods A. incompletely dominant...

A 2n=6 germline cell completes meiosis I. Each daughter cell - contains three chromosomes, each composed of two sister chromatids. A carcinogen is a chemical or treatment that - causes mutations that can affect gene activity. A deletion occurs during DNA replication, causing the guanine shown in red to be removed from the nucleotide strand. What effect is this most likely to have on the final protein? - The deletion of the G will cause a frame shift, resulting in a premature stop codon and ...

Pre-Lab Questions 1. What are chromosomes made of? Chromosomes are structures composed of DNA and proteins known as chromatin. Within chromatin, there is a component called a nucleosome. 2. Compare and contrast mitosis and meiosis. Both meiosis and mitosis start with only two chromosomes and involve the creation of new cells. However, meiosis does not involve crossing over and synapsis, whereas mitosis, which occurs in somatic cells, does. Mitosis produces body cells, while meiosis produc...
