Question
t male hurnans generally have deeper voices than do adult female humans direct result of higher levels of testosterone causing growth of the larynx. If the apes and humans alike show a trend toward decreasing larynx size in adul increasing larynx size in adult males, then A) sexual dimorphism was evolving over time in these species humans, which is the fossil records of B) intrasexual selection seems to have occurred in both species C) stabilizing selection was occurring in these species D) selection was acting more directly upon genotype than upon phenotye 37) Macroevolution is concerning larynx size A) the same as microevolution, but includes the origin of new secies B) evolution above the species level C) defined as the evolution of microscopic organisms into naked eye D) defined as a chang organisms that can be seen with the e in allele or gene frequency over the course of many generations of 38) Which of the various species concepts distinguishes two species geneticexchange between their gene pools? A) phylogenetic C) biological based on the degree B) ecological D) morphological 39) Two species of frogs belonging to the same genus occasionally mate, but the developing after a day and then die. These two frog species separate by A) reduced hybrid viability C) reduced hybrid fertility B) hybrid breakdown D) gametic isolation 40) The production of sterile mules by donkeys (jacks) is an example of A) reduced hybrid viability interbreeding between female horses (mares) and male B) hybrid breakdown D) mechanical isolation C) reduced hybrid fertility 41) Which of the following most lik A) gene B) genetic isolation, divergence, genetic drift C) divergence, genetic drift, genetic isolation describes the most likely order of events in allopatric speciation? tic drift, genetic isolation, divergence D) genetic isolation, genetic drift, divergence two most commonly occurring 42) Among known plant species, which of these have been the phenomena that have led to the origin of new species? A) allopatric speciation and sexual selection B) allopatric speciation and polyploidy C) sympatric speciation and sexual selection mpatric speciation and polyploidyExplanation / Answer
Ans- 36 ans-sexual dimorphism was developing over time in these species.
Ans-37 ans- macroevoution is used to describe large scale evolution that takes place over time, which above the species level so that answer will be option B
Ans-38 ans-C biological
The gene pool of of most populations of the same species exchange genes.
Ans-39- reduced hybrid viability -postzygotic; hybrid offspring are produced but are feeble or unable to compete for mates
Ans-40-reduced hybrid fertility
postzygotic hybrid offspring are produced but are sterile.
Ans-41-Genetic isolation, genetic drift, divergence
