Consider an individual that is homozygous for the short allele of the 5-HTT gene.
1) If this individual is exposed to relatively few stressful life events, how would you expect the probability of major depression to compare an individual that is homozygous for the long allele?
2) If this individual is exposed to many stressful life events, how would you expect the probability of major depression to compare an individual that is homozygous for the long allele?

1) If this individual is exposed to relatively few stressful life events, how would you expect the probability of major depression to compare an individual that is homozygous for the long allele?
According to the research carried out by Goldman et al., the individuals that have a short allele for 5HTT, will be more prone to be affected by any stressful traumatic event, to be inclined towards major depressive syndrome as compared to the individuals having a long arm. The greatest probability of being affected by the smallest stressful event is by individuals having S/S followed by individuals having an S/L genotype and the least is by individuals having the L/L genotype.
2) If this individual is exposed to many stressful life events, how would you expect the probability of major depression to compare an individual that is homozygous for the long allele?
If the individual has an S/S or S/L genotype, it has been reported that trauma has an even bad effect, as compared to those who do not have an S allele, I.e having L/L allele, p< 0.05.

The Bombay phenotype occurs when an individual human is
homozygous for a recessive allele at the FUT1 locus. Individuals
with this genotype do not make a precursor substance required to
synthesize the A and B antigens that sometimes appear on human red
blood cells. Regardless of their genotype at the ABO blood type
locus, individuals who are homozygous for the Bombay phenotype
allele at the FUT1 locus will appear to have blood type O on
standard blood type tests.

Flies homozygous or hemizygous for the
w1 allele of the white gene
(Xw1/Xw1 or
Xw1/Y) have white eyes, whereas flies
homozygous or hemizygous for the wa allele of
the white gene (Xwa/Xwaor
Xwa/Y) have orange eyes.
What is
the dominance relationship between the w1 and
the wa alleles, knowing that in the offspring
of a cross between white-apricot females and
white males the heterozygous females of the F1
generation (Xwa/ Xw1) have lighter
orange eyes than homozygous Xwa/Xwa
parental...
The normal chemokine receptor 5 gene (CCR5) allele “+” and a variant allele D was found...
The normal chemokine receptor 5 gene (CCR5) allele “+” and a
variant allele D was found in a population of people. The variant D
has a deletion of 32 base pairs called “Delta 32”. A sample of
people from this population were tested for the variation in the
CCR5 gene. The researchers found
16 people were homozygous for Delta 32;
165 people were heterozygous for the Delta 32 deletion;
433 people did not have the Delta 32 deletion.

In Drosophila, the recessive dp allele of the dumpy gene
produces short, curved wings, while the recessive allele bw of the
brown gene causes brown eyes. In a testcross using females
heterozygous for both of these genes, the following results were
obtained:
wild-type wings, wild-type eyes 178
wild-type wings, brown eyes 185
dumpy wings, wild-type eyes 172
dumpy wings, brown eyes 181
In a testcross using males heterozygous for both of these genes,
a different set of results was obtained:...

Based on the Huntington disease which has the gene of HTT gene.
Answer the following questions:
1a) Is the gene exonic or not?,
1b) what type of variant (SNP of CNV) and if the
resultant changes in protein or protein level.
2) Is the variant found in the non-coding region and also is it
involved in transcriptional regulation, if so describe the proposed
pathway.
3) Draw a three-generation pedigree with at least 15 family
members.
4) A narrative describing the pedigree...

Based on the Huntington disease which has the gene of
HTT gene. Answer the following questions:
1)Description of
genomic/epigenomic/cytogenetic/transcriptomic/proteomic
characterization/detection of disease (how is the genetic cause
determined)
2) Give a flow chart for determination of the genetic cause at
the clinical level (i.e. phenomic upon the first presentation to
the clinic to confirmation of genetic disorder).
calculating allele frequencies in a gene pool
In the beetles described in the animation, there were two alleles for color, brown and green. Suppose that you discover a very small population of these beetles, consisting of the individuals shown below. How can you calculate the frequency of each allele in this population?
1) to calculate the frequency of brown allele, count the number of ___ and divide by the total number of alleles in this population.
2) In this beetle population the number of brown alleles is...

Develop a case study/report on the Huntington disease
and the gene for this disease is HTT gene. When you are
developing the case study, start it from the DNA variant(a
specific variant of the HTT gene) to the phenotype of the diseased
patient.
The case report you should include the
following:
1) the Genomic coordinates of the variant of
the disease.
2) Transcript level coordinates of the variant
if within mRNA (immature or mature)
2a) 5’-UTR, 3’, intron, exon, or...
