How does the mutation related to the traits including diseases that are being inherited by the offspring from their parents? Give a little background, assumption/hypotheses, data collection and data analysis and form conclusions.
The reason spontaneous mutations do not have an immediate effect on allele frequencies in a large population is that: a. mutations are random events, and mutations may be eitherbeneficial or harmful. b. mutations usually occur in males and have little effect oneggs. c. many mutations exert their effects after an organism hasstopped reproducing. d. mutations are so rare that mutated alleles are greatlyoutnumbered by nonmutated alleles. e. most mutations do not change the amino acid sequence of aprotein.
Over the last several decades, the scientific community has gathered a large amount of information regarding genetics and genetic variation. What is a main source that leads to increased genetic variation? Top of Form Selective breeding Chromosomal mutations Recombination Genetic drift
A single base change can create devastating genetic disorder or a beneficial adaption, or it might have no effect. How do mutations happen, and how do they influence the future of a species?
Mutations are the raw material for evolutionary change, without mutations there could be no new variations among members of a population. Group of answer choices True or false
1.Scientists is doing artificial breeding experiments often use radiation or other methods to increase the mutation rate. Why is a high mutation rate useful? 2. How does mutation rate affect the speed at which a population adapts to its environment? 3. How does the mutation rate affect a population’s ability to adapt to its environment?
The equilibrium frequency of a deleterious allele under mutation-selection balance increases as: mutation rate increases strength of selection increases dominance increases none of the above
In order to perform mutation on an organism, we need: 1. A mutation probability - usually a "small" value 2. A crossover point 3. The number of organisms in the population 4. Both a and b
What is the probability of fixation of a gene in a population of 30 individuals (assume no selection for or against a mutation)? Multiple Choice 3.3% 3% 1.6% 0.16%
n class we investigated the reason cystic fibrosis is maintained in the human population in higher frequency than we expected given the deleterious effects of being homozygous at the CFTR gene. We calculated the actual mutation rate of the CFTR gene to be 6.7 x 10-7. The mutation rate expected under mutation-selection balance was 4 x 10-4. What is the most plausible explanation as to why cystic fibrosis is maintained in the human population at a higher frequency than we expect? a. Negative selection against the CFTR deleterious alleles is too weak to eliminate the alleles from the human population. b. Positive selection for the CFTR deleterious alleles is likely occurring in response to some other selective pressure in the human population, possibly resistance to typhoid fever. c. The CFTR gene has an exceedingly low mutation rate causing humans to have no genetic variation at that gene. d. The CFTR gene has an exceedingly high mutation rate and that is…
The change in the circled offspring’s genotype was caused by a mutation. A mutation is a change in a gene. Mutations happen when a mistake is made when a cell’s chromosomes are copied. How might mutations introduce variation into a population?
The most important feature that enables a gene to act as a molecular clock is Group of answer choices: a recent origin by a gene duplication event a large number of base pairs in the genome being acted upon by natural selection a reliable average rate of mutation
