All variations of genetic traits in a population improve an individual's chance of survival.TrueFalse

Individuals that are well adapted to their environment will survive and produceGroup of answer choicesbetter traits.stronger genes.fewer mutations.more offspring.

_____ implies that those genes that predispose traits that increase the odds of an individual surviving long enough to reproduce and nurture descendants will become more abundant in the population.a.Social facilitationb.The Nurture Assumptionc.The social role theoryd.Natural selection

Research has shown that powerful environmental conditions, such as overeating or smoking, can influence genetic development and pass on new traits. a. True b. False

Match the mechanism of natural selection with its corresponding description.the process by which individuals with advantageous traits have higher chances of survival and reproductionthe mechanism that allows genetic information to be passed down from parents to offspringthe period over which changes accumulate, leading to the emergence of new traits and the extinction of othersthe diverse range of traits exhibited among individuals within a populationthe outcome of natural selection, where populations become better adapted to their specific environmentsa.adaptationb.selectionc.timed.variatione.inheritance

Learning goal 2: Determine the best explanation for how new variations in genetic traits arise in a population.Random mutations cause offspring to look radically different to their parentsIndividuals acquire new traits during their lifetimesIndividuals with harmful genetic traits die before they can reproduceRandom mutations cause changes in DNA with each generation
