Bell Ringers: Week of 2 Mar – 6 Mar 2011
Monday A type of cloning occurs in many plants. In this process new plants grow from a piece of the parent plant. Strawberries reproduce this way from runners. African violets can be grown from a leaf. Pieces of potato tuber can be used to grow new potato plants, as shown below. The method of producing plant offspring shown in the diagram depends on which process?
A. mutation during natural selection
B. mitosis during asexual reproduction
C. self-pollination during regeneration
D. meiosis during sexual reproduction
Tuesday -
Which of these is most likely to result from the processes of mutation and crossing over during reproduction?
A. offspring that are genetically identical to their parents
B. offspring that are genetically identical to each other
C. decreased genetic variation among offspring
D. increased genetic variation among offspring.
Wednesday –
People who are tune deaf are unable to follow a rhythm. Scientists have evidence that tune deafness can be genetic. The pedigree below traces the inheritance of tune deafness in a family. Individuals in the pedigree are numbered. Scientists have analyzed the inheritance patterns for tune deafness and have concluded that tune deafness is caused by an autosomal dominant allele, T.
a. Provide evidence from the pedigree that conclusively determines whether or not that the tune deafness allele is autosomal dominant, not autosomal recessive
b. Identify the genotypes of individuals 5 and 6, and then draw the Punnett square for the cross of these two individuals.
c. Compare the expected percentage of each phenotype of the offspring from the cross in part (b) with the actual percentage of each phenotype observed in the children of individuals 5 and 6.
Thursday
Shelly and Jason are siblings, but Shelly looks like their father while Jason looks like their mother. Which of the following statements best explains the difference in Shelly’s and Jason’s features?
A. Shelly inherited a greater number of chromosomes from their father than Jason did.
B. Shelly inherited a smaller number of X chromosomes from their mother than Jason did.
C. Shelly and Jason had different mutations occur in the 46 chromosomes they inherited from their mother and father.
D. Shelly and Jason inherited different combinations of 23 chromosomes from their mother and 23 chromosomes from their father.
Friday - EXAM
a)
b)
During the fall reproductive season, the belly of a male brook trout becomes bright orange. The orange belly provides some camouflage and helps attract females.This trait evolved in brook trout
because, compared to males with pale bellies, males with bright orange bellies are more likely to
A. live in good habitats.
B. be eaten by predators.
C. mate with other species of fi sh.
D. fertilize eggs to produce offspring.
c)
There are two types of modern whales:
toothed whales and baleen whales. Baleen whales filter plankton from the water using baleen, plates made of fibrous proteins that grow from the roof of their mouths. The embryos of baleen whales have teeth in their upper jaws. As the embryos develop, the teeth are replaced with baleen.
Which of the following conclusions is best supported by this information?
A. Primitive whales had teeth as adults.
B. Toothed whales descended from baleen whales.
C. Baleen whales are evolving into toothed whales.
D. Descendants of modern baleen whales will have both teeth and baleen as adults.
