Field Study on Recessive Traits
Learning Objective : LS 3.1 Apply concepts of statistics and probability to explain the variation and distribution of expressed traits in a population.
Is Curly hair dominant over Straight?
I went around school seeing whether the students had curly or straight hair. In total 86 students had either straight or curly hair.
Curly haired students
22/86
Straight haired students
64/86
Hardy Weinberg Equation
q^2 = .26 ----> .51 q
1 - .51 = .49 p ----> .24 p^2
2pq 50%
Straight Homozygous AA 24%
Straight Heterozygous aa 50%
Curly Haired 26%
In conclusion Curly hair is dominant over straight hair, which is recessive.
My population in numbers were a normal distribution
I understand the Hardy Weinberg Equation
Q^2 + 2pq + P^2 = 1
P + Q = 1
