Gene pool all Study guides, Class notes & Summaries

Alleles Alternate forms or varieties of a gene. The alleles for a trait occupy the same locus or position on homologous chromosomes and thus govern the same trait. However, because they are different, their action may result in different expressions of that trait. Carrier An individual who is heterozygous for a trait that only shows up in the phenotype of those who are homozygous recessive. Carriers often do not show any signs of the trait but can pass it on to their offspring. This i...

HSC Biology Module 5 Reproduction Reproductive success The ability to produce fertile offspring that survive to reproductive maturity and produce offspring of their own. Biological fitness the measure of an individual's reproductive success. It is calculated as the average contribution to the gene pool made by a certain genotype within a population and the relative likelihood that these alleles will be represented in future generation. Sexual reproduction It involves the meet...

BI 213 midterm 2 practice exam 79 Questions with Verified Answers What is the purpose of the TATA box found in eukaryotic promoters? A) It serves as a termination signal for RNA polymerase B) It sets the translation reading frame of the mRNA C) RNA polymerase II binds directly to the TATA box to initiate transcription D) It binds the first Met-tRNA for translation of the mRNA E) It is the binding site for general transcription factors that recruit RNA polymerase - CORRECT ANSWER E ...

bio 1108 exam 1 (herrick) questions and answers 100% pass what are two factors that contribute to phenotype? - Correct Answer ️️ -genotype and environment species - Correct Answer ️️ -individuals that are able to exchange genetic material gene pool - Correct Answer ️️ -all alleles present in individuals of that species populations - Correct Answer ️️ -interbreeding groups of organisms of the same species living in the same geographical area what are two main sources that l...

BIO 107 Study Guide QUESTIONS WITH DETAILED VERIFIED ANSWERS | A+ GRADE ASSURED Microevolution Evolutionary change below the species level; Change in allele frequencies over generations. It is called micro evolution because it focuses on evolution in population, which is the smallest scale. (individuals do not evolve.) 3 mechanisms that cause allele change Natural seletion, genetic drift( chance events that alter allele frequencies), and gene flow (the transfer of alleles between populatio...
