Lab Title: Personal Genetic Profile
Date: 130301
Purpose / Objective(s):




Profile common genetic traits in myself and relatives.
Profile common genetic traits in BIO 105 class.
Compare Family vs. Class Frequency
Determine patterns of inheritance for some select traits in my family tree.
Hypotheses:


The following genetic traits should demonstrate independent genetic inheritance patterns within my
class and family.
My Family may exhibit different frequencies of traits because we are mono-ethnic
Materials / Subjects / Specimens;




.
A total of more than 200 students in Bio 105 class were asked to report common genetic traits. They
were recorded and put it in a table. (See attached table # 2).
I recorded my personal genetic information (see table# 1)
In addition to myself, I surveyed generic traits among my family to measure frequency
In addition to my immediate family, I surveyed other members to for interest
Males (4)
 Self
 Dad
 1 Brother
 1 Nephew
Females (4)
 Mom
 2 Sisters
 1 Niece

Table 1 summarizes the survey details.
The generic traits surveyed included:
o Blood type
o Blood RH
o Bent Little finger
o Hitch Hiker Thumb
o Interlacing Fingers
o Pigments iris
o Astigmatism

Results
Family

Table 1 summarizes personal genetic traits

Table 2 summarizes my parents genetic traits

Table 3 summarizes genetic traits for my grandparents

Table 4 summarizes genetic traits for my brothers and sisters
Our family is clearly an example of independent gene inheritance for these traits
Females and males seem to follow respective patterns
Class

Table 5. Summarizes genetic traits for several BIO 105 Classes including ours.

Sample population sizes range from a low of 114 for Blood type to a high of 215 for Eye color

Figure 1 shows the class statistics in graphical form for all traits
The graph shows in percentages common genetic traits among the class. Although it seems unusual,
that so few students have dimples or a widow’s peak.
Very few people in this population are blue or gray eyed.

Figure 2 shows the equivalent metrics for our Family.
Only eight persons were surveyed compared to the class of about 200
No-one in our Family is Rh positive and none have freckles or dimples.
Only about 1/3 of us have brown eyes


Figure 3 shows the percentage presence of traits in BIOL 105 sample population of about 100 males.
Figure 4 shows the percent of traits in our Family
Our family shows a distinctly different pattern of inheritance than the BIO 105 Class
Figure 5shows the percentage presence of traits in BIOL 105 sample population of about 100 females
Figure 6 shows the percent of traits in our Family
Our family shows a distinctly different pattern of inheritance than the BIO 105 Class
Figure 7 shows the inheritance pattern for tongue rolling in our family
Figure 8 shows the same inheritance for bent thumb
Analysis and Discussion

It is not surprising that there are many statistical differences between the Class and our Family.

The class data combines several classes for a total number of individuals in the junior college
population, whereas I am the only member of my family that is part of this population.

My family is the same ethnicity, whereas the study population is mixed ethnicities.

My family of 8 may not be true of our entire family of the same population size as the class data.
Conclusions / Further considerations.

My family of 8 may not be a true measurement of our entire family, including in-laws, cousins and
step relationships equal in size to of the same population size as the class

It would be interesting to do this survey in several different ethnicities and several; different
community colleges from around the nation.

Observations
1.
Some information from grandparents may not be as accurate as it can be because the information
was obtained from observing pictures and from asking relatives (mom and uncles).
2.
Some information (for example, Genotype) is missing because of the multiple combinations that make
the statement true.
3.
The Bio 105 class of over 100 students and over 200 for some traits is clearly a good sample to
compare my family with.
