In Table 2, provide expected proportions for two different MOIS: AD and SLR. The values in this table are computed using information from the Punnett Square and the specified MOI. Once the proportions are determined, we can fill in the values in Table 3, E(xpected) column. Table 2. AD proportions SLR proportions Phenotype Disease, Male Disease, Female WT, Male WT, Female Your assignment is to fill in Table 1 twice (make two copies of Table 1), once using the AD proportions in Table 2 to compute the E(xpected) column, and once using the SLR proportions in Table 2 to compute the E(xpected) column. Then, follow through, decide whether either/both/neither of the specified MOIS are consistent with the observed data, and report your results. I'll get you started with the AD MOI (Table 3): Table 3.

Notation:
D= disease allele at gene
d = wild-type allele at gene
Let's provide some information about each MOI.
AD: Each of the Fi parents is heterozygous for the D allele.
SLR: The observed F2 data are the offspring from an F1 cross where the father is
affected (disease) and the mother is an unaffected carrier (wild-type, or WT). That
is, the mother's genotype has one disease allele and one WT allele in it.
In Table 1, I provide the observed data counts (in dark blue). Notice that I stratify
by gender.

In Table 2, provide expected proportions for two different MOIS: AD and SLR. The
values in this table are computed using information from the Punnett Square and the
specified MOI. Once the proportions are determined, we can fill in the values in
Table 3, E(xpected) column.

Your assignment is to fill in Table 1 twice (make two copies of Table 1), once using
the AD proportions in Table 2 to compute the E(xpected) column, and once using
the SLR proportions in Table 2 to compute the E(xpected) column. Then, follow
through, decide whether either/both/neither of the specified MOIS are consistent
with the observed data, and report your results.
I'll get you started with the AD MOI (Table 3):

You must fill in the rest of the cells, compute the Chi-Square statistic, determine the
degrees of freedom (DF), compute the p-value, and determine whether you reject or
do not reject the null hypothesis that you specified the correct MOI.
Remember, you are doing this work for two MOIS, and remember to show all work.
