The IRS has modified its guidance regarding under what circumstances a tax return preparer must get a signed written consent to disclose or use a client’s tax information and the requirements of such a consent.
This session will cover the background and assumptions that Mendel made regarding the inheritance of particular traits, the hypotheses he developed, the experiments he performed to test the hypotheses, and the conclusions he made. In addition, how offspring acquire genes (and thus traits) from parents by inheriting chromosomes, and how the movement of chromosomes during meiosis is related to Mendel's rules of inheritance will be emphasized.
Learning Objectives
To understand how experimentation resulted in Mendel's laws of inheritance.
To accurately use common genetic terms.
To predict the outcome of genetic crosses involving one, two or three unlinked genes.
To design a genetic cross that can determine whether a trait is dominant or recessive.
To design a genetic cross that can determine the genotype of an individual.
To understand the relationship of meiosis to Mendelian inheritance and Punnett Squares.
This session will explain why inheritance does not always follow Mendel's rules, or the rules predicted for the chromosome theory of inheritance. Because thousands of different genes are found along a single chromosome, and only one of the pair of chromosomes found in the parent is passed to the offspring, Mendel's law of independent assortment cannot apply to all genes. Because homologous chromosomes can exchange DNA, resulting in recombination, alleles of genes found on the same chromosome in the parent are not necessarily inherited together. Thus the pattern of inheritance depends upon the location of the genes studied with respect to one another. Mating experiments can be used to map the relative distance between linked genes.
Learning Objectives
To understand why Mendel's laws of inheritance do not apply to linked genes.
To understand the linear arrangement of genes along a chromosome.
To understand how meiosis and crossing over results in recombinant gametes.
To predict the outcome of genetic crosses involving one, two or three linked genes.
To draw a simple genetic map based upon data from test crosses.
Genetics in humans cannot be studied by performing controlled crosses rather, analysis of inheritance patterns in an existing population must be used. An approach, called pedigree analysis, is used to study the inheritance of genes in humans. This session will outline how to construct a family pedigree, and how to interpret the information in a pedigree using Mendel's laws of inheritance and an understanding of the chromosome theory of inheritance.
Learning Objectives
To construct a pedigree based on a family history.
To analyze the information in a pedigree by applying the laws of inheritance.
To determine the mode of inheritance of a trait based upon the information in a pedigree.
To predict the probability a child of particular parents would inherit the trait in question.
