Give the nucleotide positions of all single-nucleotide polymorphisms (SNPs; nucleotide positions where individuals vary in a single nucleotide base) in these sequences. How many different haplotypes (sets of linked variants) are found in these eight sequences

1st has A and G whereas 2nd has C and T.

Explanation:

There are three common haplotypes present in the population. The first single nucleotide polymorphism has A and G alleles while on the other hand, the second single nucleotide polymorphism has C and T alleles. The four possible combinations of haplotypes for the above two single nucleotide polymorphisms are AC, AT, GC, and GT.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".

meiosis is the correct answer
