If no repeats present the D1S80 length is 148 nucleotides (nt). First repeat is 14 nt and then 16 nt thereafter...keep adding until you reach your total sequence length and that will give you your total number of repeats.
Use the Hardy-Weinberg formula for simple two locus alleles. p^2 + 2pq + q^2 = 1 say you have a population of 100 organisms. 60 of these are homozygous dominant ( the p ), so 60/100 give the...
You inherit two alleles, one maternal and one paternal. Because both parents are homozygous, each only has one variation to pass down. This means that any offspring will be heterozygous and have one...
