Genetics and Inheritance
100
Selection that favors BOTH of the extremes (or both homozygotes). A population of black, white and gray rabbits in an environment with black and white rocks could serve as an example of this. Black rabbits could hide in black rocks and white rabbits could hide in white rocks. The gray rabbits would have a hard time hiding anywhere.
What is disruptive selection?
100
The definition of a species.
What are organisms that can mate and produce viable offspring?
100
The difference between anaphase I and anaphase II.
What is in anaphase I homologous chromosomes separate and in anaphase II sister chromatids separate?
100
What is the probability that a left-handed person and a heterozygous right handed person have a left-handed child?
What is 1/2?
200
The disproportionate representation of a certain allele due to a population at one point being reduced to a select few individuals that had a high representation of this allele. The Askenazi Jews are an example of this. During WWII, their populations decreased significantly. By chance the remaining population had a high number of the allele that codes for the deadly disease, Tay-Sachs.
What is the bottleneck effect?
200
The reason why biodiversity is essential for evolution.
What is -provides variation for natural selection to act on OR -ensures that not all individuals/species are killed off by a disease/event?
200
The name of the phenomena that occurs when chromosomes fail to properly separate. Also name at least on disease that it causes.
What is nondisjunction, Down's, Turner's, Klinefelters?
200
Draw a pedigree that demonstrates autosomal recessive inheritance.
What is ...?
300
Selection that causes an increase in allele frequency of a specific allele, or one or the other of the homozygous genotypes. The increase of beak size in finches due to a high proportion of large seeds in an ecosystem could be considered an example of this.
What is directional selection?
300
Evolution that causes unrelated organisms to have similar traits.
What is convergent evolution?
300
The function of mitochondria and an explanation of how they use their double membrane to perform their job.
What is to provide the cell with usable energy? The membranes separate ions causing a charge, which then powers ATP synthase, a chemical machine that produces ATP for the cell.
300
The proof mathematically why x-linked traits are more commonly shown in men.
What is XaXa=trait, XAXa=no trait, XAXA=no trait, XaY=trait, XAY=no trait?
400
Selection that leads to a high proportion of heterozygotes due to the heterozygote advantage. Sickle cell is an example of this.
What is stabilizing selection?
400
In corn, yellow kernel color is governed by a dominant allele; white, by its recessive allele. A random sample of 1,000 kernels from a population that is in equilibrium reveals that 910 are yellow and 90 are white. What are the frequencies of the yellow and white alleles in this population? What is the percentage of heterozygous in this population?
What is p=0.7, q=0.3? 42%?
400
An explanation of the regions within a genome that must be mutated in order for a cell to become cancerous.
What is there must be a mutation causing a malfunction of tumor suppressor genes (reducing or eliminating their function) as well as a mutation in a proto-oncogene, turning it into an oncogene (amplifying its function).
400
Draw two images starting with two pairs of chromosomes (one from mom one from dad) and show how they would separate in meiosis and how they would separate in mitosis.
What is ...?
500
Natural selection is the method for evolution. Darwin described evolution as descent with _________________. These come in the form of ______________________.
What is modification, mutations?
500
An organism/species from which two or more species evolved?
What is a common ancestor?
500
The purpose of the three checkpoints within the cell cycle.
What is to check for go signals, to check that DNA has been copied accurately, to check that spindle fibers are attached?
500
Name and explain at least two types of Non-Mendelian inheritance.
What is....?
