Answer #1

The right answer is new alleles being added to the population as necessary.There is selection of individuals which are more suitable and adapted and they produce more offspring so their allelic and gentypic frequency will change.Similarly in case of Darwin finches these have a common ancestor and then evolved according to the habitiat They all have the similar but not identical beaks.The fitness of the individual which is better adapted would be more.the answer is 1)

Which of the below statements is NOT a legitimate mechanism by which natural selection can maintain genetic variation in a population. Overdominance. When there is heterozygote advantage, as long as a population starts with two alleles (i.e., is not fixed for one or the other allele) both alleles will be maintained at a stable equilibrium. Fluctuating selection. Temporally or spatially varying selective regimes that favor different genotypes can preserve genetic variation. The maintenance of variation by this mechanism requires a...

Which one is best statement of Evolution is ? A shift in allele frequency due to mixing of species B a change in allele frequency because a selection pressure has caused mutations C a change in allele frequency because individuals with a particular allele have a selection advantage in a particular environment D the divergence of traits in different species as a result of the same selection pressure

Which following statement(s) is(are) true? (Circle all the correct answers) A. The favorable dominant allele can hardly be fixed by natural selection. B. A genotype resulting in lower reproductivity will have lower fitness value. C. The higher selection coefficient is, the higher the fitness is. D. Larger starting allele frequency for the unfavorable alleles can fasten the increase of allele frequency for the favorable alleles.

Selection can act in different ways. Match the type of selection with the correct description below. 1.The frequency of dominant and recessive homozygotes is high, with only a small     number of heterozygotes 2.Two extreme phenotypes related to eye size occur in high frequency in a population 3.The frequency of big-eyed individuals shifts to a higher frequency in the population 4.The mean value of a phenotype is maintained in a population across generations

In systems in which there is strong male-male competition for mates, natural selection should favor a strategy in which females in poor condition produce female offspring preferentially.      T     F All scientists have agreed on what criteria must be met before two populations can be designated as separate species.      T     F When two populations are separated geographically with no gene flow happening between them, genetic drift will always act in both populations, causing the populations to diverge.      T     F Exploitative interactions,...

Which statement below describes one of the reasons scientists were initially slow to accept natural selection as a major mechanism of evolutionary change: a) many scientists assumed inheritance worked through a blending mechanism, so variation required for natural selection would be rapidly lost from populations (b) many scientists assumed inheritance was particulate (as described by Mendel), so variation required for natural selection would be rapidly lost from populations (c) Many scientists assumed differences in fitness among individuals in a population...

Which of the following is not an important condition that must be met for natural selection to occur? A. Traits must vary in some way B. Mating must be random among the individuals within a population C. Variations influencing reproductive success must be heritable D.Differential reproduction/survival among individuals with different traits I think C and D (Variation and Differential reproduction ) are two important conditions. However, I am not sure. the answer A or B

Huntington Chorea is a serious genetic disorder caused by a rare dominant allele (H) at an autosomal locus on chromosome 4. Individuals bearing an H allele produce a damaging protein that accumulates within the brain, leading to progressive loss of motor control and often to dementia. The disease often manifests itself later in life, and usually, Huntington Chorea victims die within 15 years after their neurological symptoms are diagnosed, but some people die before even being diagnosed. In some rural...
