Polar molecules (with +/- charges) are attracted to water molecules and are hydrophilic. Nonpolar molecules are repelled by water and do not dissolve in water; are hydrophobic.
Most adult stem cells come from the bone marrow.

The sets of alleles for each parent are Dm for the mother and DM, Dm, dM, and dm for the father. This information is fundamental for estimating genotype and allele frequencies in offspring.
<h3>What are alleles?</h3>
Alleles are gene variants for a given gene <em>locus</em>, diploid organisms inherit two alleles for each locus (one from each parent).
Gametes are germinal (haploid) cells that carry specific allele combinations.
The analysis of gamete combinations is fundamental to estimate genotypes and allele frequencies.
