Mendelian Inheritance Lab Report

Mendelian inheritance is centered around three laws discovered by Gregor Mendel. First is the law of segregation which states that during the formation of gamete the two allele pairs separate randomly. The second law is independent assortment which states during gamete formation each pair of the allele will segregate independently of the rest of the pairs of the chromosomes. The third law is the law of dominance which is that alleles can be dominant or recessive with the expression of the dominant trait when a minimum of one dominant allele is present. Mendel described inheritance as the passing of genetic information from one generation to its offspring what can now be termed as a gene.

The Hardy Weinberg Principle is achieved through the …show more content…
This was calculated by using a calculation to determine the allele frequencies of the observed alleles for the blue and green locus. This is calculated for each allele pair, when these are totalled up they should equal 1. In some case, this can be just above or below 1 which is due to the limits of rounding but should be calculated to 1 with all the raw data calculations. At each stage of determining Hardy Weinberg proportion the differences between the expected and the observed must be analysed to determine if the difference is statistically different. This is done through a Chi Square analysis; the p value represents the level of statistical significance. A value is deemed significant if the p value is less than 0.05 however if this is not the case then the difference is not statistically different and the likelihood of chance acting alone cannot be ruled out. The limitations of using this test was that the data were rounded to 3 decimal place to total correctly so the full significant numbers could not be used which is the reason some calculation checking does not always equal one
