The idea of a Haplotype Beyond Haploid

H. sapiens <100, 000 yrs. ± 4000 generations *Few recomb. /gen. *Haplotypes are of significance

Essentially Haploid: Haplotypes WITHOUT recombination

Note: In humans, the mutation rate is ± 10 -8 (per generation per bp) Y chromosome is 60 Mbp, so +/- 0. 6 bp change/generation Remember: For Y, recombination is NOT AN ISSUE 100000 years =± 4000 generations = D 2400 bp 3500 years =± 140 generations = D 90 bp

Y- haplogroup distributions now

Note: In human mitochondria, the mutation rate is ± 10 -5 (per generation per bp) Mitochondrial genome is about 17, 000 bp, so +/- 0. 2 bp change per generation Here too: For Mitochondrial DNA, recombination is NOT AN ISSUE

The idea of a Haplotype

For AUTOSOMAL inheritance and haplotypes, we must address: -diploidy -crossovers/recombinant chromosomes *Additional levels of complexity

For Autosomes: Two alleles of each gene 127 c. M For Autosomes: crossovers and recombinant chromosomes

Take into account the dynamics/timing of: -single base pair changes -crossovers/recombinant chromosomes

For AUTOSOMAL inheritance and haplotypes, we must address: -diploidy -crossovers/recombinant chromosomes Prof. Rosie Redfield, UBC -Link to movie is on Moodle
