Biology Unit 4 Chapter 8 - Inheritance and Selection Graded A+ Phenotype Definition Phenotype refers to the observable characteristics of an organism, which result from the interaction between its genetic makeup (genotype) and environmental influences. Tay-Sachs Disease and Genetic Evidence 1. Recessive Allele Evidence: In the provided family diagram, individuals 3 and 4 are unaffected but have children who are affected by Tay-Sachs disease. This indicates that both must be carrie...

using the hardy-weinberg principle, what happens to p and q w/ random mating Ans: nothing, their values don't change when detecting carriers, what happens to P(Bb) and n increases Ans: P(Bb) decreases as n increases, creating a higher level of confidence in detecting a carrier migration Ans: the movement of alleles from 1 population to another what do the proportion of alleles in a new population depend on Ans: immigration rate + difference in allele frequencies between the 2 populatio...

BIO CHAPTER 14 Exam Questions With 100% Correct Answers. Bottleneck effect - answerA type of genetic drift that occurs when a population is suddenly reduced to a small number of individuals, and as a result alleles are lost from the population. founder effect - answerA type of genetic drift in which a small number of individuals leaves one population and establishes a new population, resulting in lower genetic diversity than in the original population. genetic drift - answerRandom changes...

NVCC BIO 101 EXAM 2&3 CORRECTRY ANSWERED ANS PASSED What are fossils? - ANSWER remains of animals or plants once alive in sedimentary rock What part of the animal is usually left in a fossil? - ANSWER skeletons and bones What are the two things in which whole animals are found? - ANSWER amber and ice A scientist who digs up and studies fossils is called a- - ANSWER paleontologist No two people are genetically identical, except for identical twins, the main source of genetic vari...

Natural Selection the process that results in adaptation of a population to the biotic and abiotic environments. Polygenic controlled by more than one pair of alleles located at different gene loci Directional Selection occurs when an extreme phenotype is favored and the distribution curve shifts in that direction. Example: resistance to antibiotics and pesticides Stabilizing Selection Occurs when an intermediate phenotype is favored. Individuals near the average are fav...

Hardy-Weinberg equilibrium principle states Answer allele frequencies in a population will not change from generation to generation; if allele frequencies are p and q, genotype frequencies will be p^2, 2pq, q^2 mechanisms of evolution Answer drift, selection, migration, mutation population genetics Answer integrates natural selection with Mendelian genetics evolution is ______ in a population Answer change in allele frequency species are not immutable Answer microevolution lineage...

Evolutionary Analysis question and answers graded A+ 2023 Homologous genes - correct answer Genes that share a recent common ancestor based upon phylogenetic analysis Orthologous genes - correct answer homologous genes that are found in different species that are due to speciation events Paralogous Genes - correct answer homologous genes that are due to a duplication event in a particular species Brachydactyly - correct answer Shortness of the digits caused by autosomal dominant allele...
