Evolutionary analysis ch. 2 question n answers graded A+ 2023Lamarck - correct answer in 1809 that all species are derived from gradual evolution. He guessed it was driven by the inheritance of acquired traits. Said simple life forms are spontaneously generated from nonliving matter. His ideas were popular until the 1930s Vestigial structure - correct answer remnant of a structure that may have had an important function in a species' ancestors, but has no clear function in the modern species...

Chapter 5 Evolutionary Analysis question well answered rated A+ 2023variation - correct answer ____ among individuals is the raw material for evolution genetic variation environmental variation genotype-by-environment interaction - correct answer three types of variation are genetic variation - correct answer ex: newborn's skin color environmental variation - correct answer ex: skin exposed to light genotype-by-environment interaction - correct answer ex: when two friends with sim...

Evolutionary Analysis Exam 2 question n answers graded A+ 2023quantitative genetics - correct answer evolution at multiple loci used to predict whether and how populations evolve loci - correct answer specific location/ position on a gene, DNA sequence, or chromosome quantitative traits - correct answer traits with cont variation that need to be measured qualitative traits - correct answer traits that can be categorized (discrete phenotypes) genotypes at different loci -mendelian al...

Evolutionary Analysis Exam 2 fully solved 2023 passedgenetic variation - correct answer differences in alleles or genotype as shown by various phenotypes How was genetic variation studied early on? - correct answer they studied proteins, because different proteins are produced by genetic variations. (doesn't show variation in substitutions though) allele example - correct answer B, b genotype example - correct answer BB, Bb, bb environmental variation - correct answer if a phenotype...

Evolutionary Analysis Exam 1 Question and answers graded A+ 2023What does HIV stand for? - correct answer human immunodeficiency virus (HIV) Which of the following enzymes is responsible for transcribing viral RNA into DNA? a) Reverse transcriptase b) Reverse integrase c) RNA duplicase d) DNA polymerase e) RNA polymerase - correct answer Reverse Transcriptase A derived character that is shared among two or more lineages is also a(n) ___________ a) apomorphy b) pleisomorphy c) s...

Evolutionary Analysis Exam 1 question and answers graded A+ 2023 Hardy-Weinberg equilibrium principle states - correct 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 - correct answer drift, selection, migration, mutation population genetics - correct answer integrates natural selection with Mendelian genetics evolution is ______ in a population...

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...

When genotypes at one locus of a chromosome are independent of genotypes at another locus of the same chromosome, the two loci are ________. Answer in linkage equilibrium When genotypes at one locus of a chromosome are nonrandomly associated with the genotypes at another locus of the same chromosome, the two loci are ________. Answer in linkage disequilibrium Which of the following can produce linkage disequilibrium? Answer -genetic drift -selection on genotypes of more than one locus -m...

Successful artificial selection, such as that practiced by plant and animal breeders to modify their crops and livestock, depends on which of the following? Answer All of these are necessary for artificial selection to take place. Darwin's postulates must be true for selection to occur, whether it is artificial selection or natural selection. Thus, for artificial selection to occur, the population must have variation in the desired trait, the variation must be heritable, and breeders must b...

The pope said " (HIV) cannot be overcome by the distribution of condoms. On the contrary, they increase it" Is the popes first statement correct? How about his second statement? How do we know? Answer The Pope's first statement is that Africa's problem with HIV/AIDS "cannot be overcome by the distribution of condoms." The statement is true in that no single strategy will prevent the transmittal of HIV/AIDS. For instance, condoms provide some protection from sexually transmission of HIV/...
