Probability of
Polydactyly
Polyfdactyly
- One in every five hundred humans are born with extra digits
- .4% of humans have it and 99.6% do not
Whi?
- Hardy and Weinberg set out to fail at disproving evolution
- Concocted conditions that would eliminate evolution

Fun
Finger Facts
- Only works if five conditions are met
- Mathematical Equation:
- p+q=1 [phenotype]
- p(p)+2pq+q(q)=1 [genotype]
- Use the frequencies of the alleles in place of 'p'&'q'
- p(p)=homozygous dominate, pq=heterozygous, q(q)=homozygous recessive
- Polydactyly follows an autosomal dominant pattern of inheritance. Its is not sex linked, and the parent’s offspring have a 50% chance of inheriting the disease
- 8 infants were born alive with polydactyly in the UK 2002 (University of Ulster, 2003)
- 0 fetal deaths or stillbirths occurred due to polydactyly in the UK 2002
- 3 cases of induced abortions occurred following prenatal diagnosis of polydactyly in the UK 2002 (University of Ulster, 2003)
- Polydactyly occurred in 3.74 per 10,000 births in the UK 2002
Double Dose of Digit
Digression
- 4 infants were born alive with syndactyly in the UK 2002
- 0 fetal deaths or stillbirths occurred due to syndactyly in the UK 2002
- 3 cases of induced abortions occurred following prenatal diagnosis of syndactyly in the UK 2002
- Syndactyly occurred in 2.38 per 10,000 births in the UK 2002

- Combination of biology and statistics
- Deals with population genetics and gene frequencies in populations
- Must have five conditions met
- large population
- random breeding
- isolation of populations
- no/limited mutations
- No natural selection
