Unit Eight: Genetics
1.
List several features of Mendel’s Methods that contributed to his success and state four components of Mendel’s hypothesis on inheritance
2.
Describe a testcross and explain how it is useful in breeding experiments
3.
Describe Mendel’s laws of segregation and independent assortment. Relate these laws to our understanding of the events of meiosis and explain how these events result in genetic variation.
4.
Describe how Chi Square data was used to support Mendel’s laws.
5.
Distinguish between genotypes and phenotypes, heterozygous and homozygous, dominant and recessive alleles.
6.
Describe how the laws of probability are used to calculate the chances of an individual having a specific genotype of phenotype
7.
Use a Punnett square to predict the results of monohybrid and dihybrid crosses and to calculate the genotypic and phenotypic ratios of each.
8.
Define and give the examples of traits displaying incomplete dominance and codominance.
9.
Describe the inheritance of the ABO blood system and explain why the A and B alleles are codominant
10.
Define polygenic inheritance Explain how quantitative analysis can be used to predict traits that display polygenic inheritance.
11.
Given information about the inheritance of a gene within multiple generations of a family infer the pattern of inheritance for the trait.
12.
Explain how a lethal recessive gene can be maintained within a population and why lethal dominant genes are rarer than lethal recessive alleles.
13.
Explain why Consanguinity increases the probability of homozygosity in the offspring.
14.
Describe the inheritance pattern and phenotypic effects of Tay Sachs disease , sickle cell anemia and Huntington’s Disease.
15.
Explain how errors in meiosis can result in monosomy, trisomy and polyploidy. Given examples of human diseases caused by monosomy and trisomy (including a description of the disease phenotype) and effects of polyploidy in plants
16.
Explain the inheritance of Sex-Linked traits and why these traits are more commonly observed in male offspring. Give Examples of sex-linked diseases in humans,
17.
Explain the relationship between the frequency of crossing over and the relative locations of genes on a chromosome.
18.
Explain how data from test crosses can be used to determine if genes are linked or are located on separate chromosomes and relate the data to events in meiosis.
19.
Calculate recombination frequencies from testcross data and use the frequencies to determine relative gene locations of linked genes.
20.
Describe the role of environmental factors in the expression of an organisms phenotype using human height and weight as examples.
21.
Describe how a genome can exhibit a flexible response by explaining the relationship between the expression of dark fur coloring on the feet and ears of a Himalayan rabbit and the environemntal temperature
