Textbook Question
Chapter 19, Problem 11RQ
When closely related individuals mate with each other, or inbreed, the offspring are often not as fit as the offspring of two unrelated individuals. Why?
- Close relatives are genetically incompatible
- The DNA of close relatives reacts negatively in the offspring
- Inbreeding can bring together rare, deleterious mutations that lead to harmful
phenotypes - Inbreeding causes normally silent alleles to be expressed.

There is some evidence that selection on white fur color in cats resulted in unintentional selection on hearing abilities. About 40% of white-furred, blue-eyed cats are also deaf. It turns out the gene responsible for pigmentation here also affects the fluid in the ear canals. This is most consistent with what phenomenon in genetics?
Inbreeding
Linkage
Heritability
Pleiotropy
Organizations that aim to protect the rights of animals have been battling leisure breeders to stop selective breeding because they view it as a form of abuse or cruelty to animals. Selective breeding or artificial selection is a mechanism that has brought a huge impact on the gene frequency of animals especially domesticated ones like dogs and cats. There are cases when breeding animals such as dogs resulted in diseases and malformation or abnormalities in the resulting offspring.
Is s it proper to continue selective breeding? Support your claim and your answer in a bulleted format.

Polymorphism of body color is caused by two alleles in a fly. One allele's homozygotes are brown, other homozygotes allele are pale, whereas heterozygotes have orange color. This is the observation made by the experimenters:
brown: 100
pale: 100
orange: 50
find the genotype frequncy under hardy-weinberg equil. and then show the calcultaions to find the coefficient of inbredding for this locus.

- The reason spontaneous mutations do not have an immediate effect on allele frequencies in a large population is that: a. mutations are random events, and mutations may be eitherbeneficial or harmful. b. mutations usually occur in males and have little effect oneggs. c. many mutations exert their effects after an organism hasstopped reproducing. d. mutations are so rare that mutated alleles are greatlyoutnumbered by nonmutated alleles. e. most mutations do not change the amino acid sequence of aprotein.arrow_forwardThe beetle pollinators of a particular plant are attracted to its flowers' bright orange color. The beetles not only pollinate the flowers, but they mate while inside the flowers. A mutant variant of the plant producing red flowers becomes more common with the passage of time. A particular variant of the beetle prefers the red flowers to the orange flowers. Over time, the two beetle variants diverge from each other to the point that interbreeding is no longer possible between them. What kind of speciation has occurred in this example, and what has driven it?

- Two pair of alleles are known to interact in the production of feather color in parakeets. Allele B is needed for Blue pigment, whereas the recessive “b” resulted in lack of color. The dominant C is associated with yellow pigment whereas the recessive allele “c” also resulted in lack of color. Blue and Yellow pigments together produce green feather color.

- Background: In class we did a project about m and m’s and there ability to evolve and natural selection. (Yes I know they can’t actually evolve it was just used as a example in class) however I can’t figure out this question. Occasionally a mutant may occur and produce a candy that is misshapen or Pointier or flatter than the rest. Often this proves to be a weakness, but a rare mutation may confer extra M&M durability. Other mutations in M&Ms could occur ( like ones that result in a new color). A mutant un you population represents a new _________. What goes in the blankarrow_forward2) The year is 2050. The climate has continued to warm. Areas in northern Canada and Alaska are without snow or ice; the average annual temperature has risen and previously snow-covered areas are now shrub land and some temperate forests. What effect would such a climatic change have on the gene pool of the rabbits? All BUT ONE could apply. In northern Canada, a population of rabbits was predominantly white in color. The allele for white color is recessive (g) while the allele for gray color is dominant (G). Over the last several decades, the average annual temperature of this area has increased and the long-term deposits of ice and snow have become scarce. In this case, the frequency of a previously rare allele becomes more frequent in the population. Choose one.A) The allelic frequency has most likely shifted to 85% GG and 15% gg. B) The dominant allele in the gene pool would become G, the previously rare allele. C) The allele for white, g, would be scarce and perhaps nonexistent…arrow_forwardBoxers are far more inbred than poodles.
