Male dragonflies of one species are unable to grasp the abdomen of female dragonflies of a different species securely enough to mate, due to poor alignment of the four wings on each insect. This type of interference during mating attempts between different dragonfly species is: A. an example of a pre-zygotic barrier due to behavioral isolation B. an example of a pre-zygotic barrier due to gamete isolation C. an example of a pre-zygotic barrier due to mechanical isolation D. an example of a pre-zygotic barrier due to habitat…arrow_forward

The herbivorous Japanese ladybird beetle Henosepilachna yasutomii (which feeds on blue cohosh), and the sympatric beetle Henosepilachna nipponica (which feeds on thistles), do not ordinarily interbreed because they are reproductively isolated by which pre-zygotic barrier?

- 17) Imagine the recessive allele of gene B above is a beneficial trait for individuals of the species to have, but the recessive allele of the C gene is detrimental. Imagine also, you only have two individuals from which you wish to build a successful population: one is homozygous dominant for the two genes and the other homozygous recessive for the two genes. Considering the table of recombination rates above, if you mate these two individuals, what percentage of the resulting offspring will have both beneficial alleles? 18) Theoretically speaking, we should not be able to observe a recombination rate greater than 50%. Why is this so? If we measure a recombination rate of 50% what does it mean? 19) Create a chromosome linkage map for the seven genes provided. Numbers represent the recombination rates among offspring who have parents who are each pure-bred for the alleles of genes described. Assuming the gene for eye color is 25 map units from the end of the chromosome, provide a list…arrow_forward. Examining how populations lead to new lineages that arise based on alterations to allelic frequency and gametic exchange of new alleles is investigating ________________ a) macroevolution b) microevolution c) community ecology d) ecological species concept 2.
