Are dimples dominant or recessive?
Learning Objective : LS 3.1 Apply concepts of statistics and probability to explain the variation and distribution if expressed traits in a population.
The assignment given to us was to pick a trait and ask fifty people. I chose dimples.
Dimples:
21/50
No dimples:
29/50
So in order to find out what trait is dominant I used the Hardy-Weinberg equation.
29/50
q^2= 0.58
q= 0.76
p= 1 - 0.76= 0.24
2pq = 0.36
Dominant for dimples: 24%
Recessive for dimples: 76%
Heterozygous for dimples: 36%
In conclusion although having dimples is a dominant trait, I found that more people do not have dimples.
