1) In a general genetic bottleneck, the population is reduced because of massive death. True or False  2) It is possible for a response to selection to happen if the trait is NOT heritable. True or False

Create a fictional trait that Selection is acting against and describe: 1) What the trait consists of (i.e. a disorder, a physical characteristic, a behavior, etc). 2) The genotype or genotypes that express the trait 3) How the trait affects individuals with genotypes that do not express the trait (100 words minimum; no sources required)

"The use or disuse of a trait explains why it evolved or was lost."   Please explain in detail why this is false and a misconception.

It is not E. please figure it out.

Generally speaking, natural selection tends to select for dominant alleles while genetic drift tends to favor recessive alleles. 1)True 2)False

Which of the following is true?   Question 10 options:   a)  A person's phenotype is a trait that is the result of the environment only.   b)  A person's phenotype is a trait that is the result of genes only.   c)  A person's phenotype is a trait that is the result of genes and the environment.   d)  A person's genotype is a trait that is the result of genes and the environment.

Which one of these statements concerning polygenic and multifactorial traits is NOT true?     they can either be continuous or discontinuous     a smooth gaussian distribution can occur through environmental influences     a smooth gaussian distribution can occur through increasing numbers of genes     polygenic traits require the additive effect of many genes; multifactorial traits do not

Associated SNPs outside of gene no effect on protein production or function. T G Associated SNPs within gene no effect on protein production or function Regulatory sequences A Coding region с T Noncoding SNP: changes amount of protein produced www.Biolnteractive.org Causative SNPs within gene Unassociated SNP far from gene on same chromosome or different chromosome Protein Coding SNP: changes amino acid sequence b. Which types of SNPs might be identified in a GWAS? 4. Consider the different types of SNPs shown in Figure 3: associated, unassociated, and causative (including both noncoding and coding). a. Which types of SNPs affect protein production or function for the gene of interest? Figure 3. A diagram showing various ways in which a SNP could be associated with a certain gene and its trait. GWAS in the News Read the following news release, which describes a GWAS study with dogs. Note that a dog's coat refers to its fur or hair. Variants in Three Genes Account for Most Dog Coat…

72)The four figures below show the expression of a trait by three genotypes (the three lines) in two environments (A & B). Which graph shows the most variation in phenotypic plasticity? B   A   D   C

A dominant allele that arises from recurrent mutation is mildly deleterious. The fitness of heterozygotes is 99% of normal. The phenotype appears in about 1 out of every 10,000 newborns. What is the allele frequency? Assuming that there is a mutation/selection balance, estimate the mutation rate. (this is all the information given on the question
