Epistasis is a genetic concept where one gene masks the effect of another gene. Here is a practice problem for you to work on:
In a hypothetical organism, gene A controls the production of enzyme X, while gene B controls the production of enzyme Y. If enzyme X is necessary for the production of enzyme Y, what would be the phenotypic ratio of offspring from a cross between two individuals who are both heterozygous for gene A and gene B?
Here are some examples of Hardy-Weinberg problems for practice: In a population of 500 individuals, 25 exhibit the recessive trait for a certain gene. What are the frequencies of the dominant and recessive alleles in the population? If the frequency of the homozygous dominant genotype in a population is 0.36, what is the frequency of the heterozygous genotype? If the frequency of the recessive allele in a population is 0.2, what is the expected frequency of individuals with the homozygous recessive genotype? These problems can help you practice applying the Hardy-Weinberg equilibrium to genetic populations.
Here are some examples of restriction mapping practice problems: Given a DNA sequence and the locations of two restriction sites, calculate the size of the fragments produced after digestion with a specific restriction enzyme. Determine the order of restriction sites on a DNA molecule based on the sizes of the fragments produced by different combinations of restriction enzymes. Analyze a restriction map to identify the locations of specific genes or genetic markers on a DNA molecule. These practice problems help students understand how restriction mapping is used to analyze and manipulate DNA sequences.
Here are a few examples of Hardy-Weinberg practice problems for you to try: In a population of 500 individuals, 25 exhibit the recessive trait for a certain gene. What are the frequencies of the dominant and recessive alleles in the population? If the frequency of the homozygous dominant genotype in a population is 0.36, what is the frequency of the heterozygous genotype? If the frequency of the recessive allele in a population is 0.2, what percentage of the population is expected to be carriers of the recessive trait? These problems can help you practice applying the Hardy-Weinberg equilibrium to calculate allele and genotype frequencies in a population.
Here are a few practice problems to help you understand Hardy-Weinberg equilibrium: In a population of 500 individuals, 25 exhibit the recessive trait for a certain gene. What are the frequencies of the dominant and recessive alleles in the population? If the frequency of the homozygous dominant genotype in a population is 0.36, what is the frequency of the heterozygous genotype? In a population of 1000 individuals, 64 exhibit the dominant trait for a certain gene. What are the expected frequencies of the three genotypes (homozygous dominant, heterozygous, homozygous recessive) in the population? Try solving these problems using the Hardy-Weinberg equations and principles!
Hardy-Weinberg problems typically involve calculating allele frequencies and genotype frequencies in a population under certain assumptions. For example, you may be asked to determine the frequency of individuals with a specific genotype, or to calculate the frequency of a particular allele in a population.

You go through some practice problems for the module set. For example, if you did Geometry, they would have problems about geometry. After that, you do practice problems, except they are word problems. In the end, you take a test on the module. If you pass, congratulation! If you fail, you'll have to retake the test.
There are several sites that provide LSAT Practice Tests. Some of them provide study guides to work on before you do the practice tests, as well. Here is one site: http://www.testpreppractice.net/LSAT/Free-Online-LSAT-Practice-Tests.aspx
Some companies paid them money to ignore these problems.

Practice a lot. Do some reading, think about it. Consult about problems with others. Teach others.

read chapter 4 in your textbook, take notes, practice some problems an then try to do the frappy
I'll type up some practice temps; the formula is on the discussion page. 34.5 C = F -67 C = F 2 C = F -156 C = F
