I’m working on a biology question and need an explanation to help me study.1) A mutation produces a new beneficial dominant allele. Which of the following statements is false when considering the rate of freq. change that will be observed for this allele in the population-alelle will initially be present in heterozygotes-it is less likely to reach a freq. of 1. than if it had been recessive-its freq will increase slowly until homozygotes occur in the population-individuals with this allele will express favorable phenotype2)Which of the following is not an exampleof a component of fitness-number of eggs a female can produce-how long you live past reproductive age-number of females a male mammal mates with in a breeding season-ability of a sperm to successfully fertilize an egg3)Which of the following is not associated with Darwins theory of evolution-individuals in a population vary phenotypically-more organisms are produced than can survive-there are limited resources for which individuals compete-all variations possessed by individuals of a population are inherited4) What type of selection leads to the fixation of an advantageous allele-positive-overdominant-underdominant-all above5) Which of the following is true when considering linkage disequilibriumA-it decreases as recombination rate increasesB-it measure associations among alleles at different lociC-it cannot cause an allele at a neutral locus to change in frequencya and Ba,b,c6) Which is false when considering a populations mean fitness(w)-natural selection causes populations to evolve so that they become better adapted to their enviornment-the average survival and reproduction of the population members increases over time-fitness gains made by selection are continuously undermined by environments that change in space and time-none of the above are false7)What type of selection would decrease phenotypic variation in a trait but the mean of the trait would not change-stabilizing-directional-disruptive-positive8)Newborn mortality in the colony tends to be 5-10%. A series of genetic crosses suggests that the deaths in the newborns is due to a lethal recessive allele. What is the reasonable explanation for the persistence of this allele in the colony?-homozygous recessive mice have a reproductive advantage-the lethal allele reoccurs each generation due to a high mutation rate -recessive allele cannot be selected against when it is in the heterozygote -there is no dominance in heterozygotes 9) Which is NOT a misconception or misguided inference about evolution? -evolution can prepare an organism for a future event that can impact its fitness- a phenotype cannot solely be the product of physics or chemistry -all aspects of an organism are the outcome of nonrandom process( ie natural selection) -natural selection is constrained by past evolutionary events
