Polar<span> molecules
water molecules have a weak, partial negative charge at one region of the molecule (the oxygen atom in water) and a partial positive charge elsewhere (the </span>hydrogen<span> atoms in water).The force of attraction is called a </span>hydrogen bond<span>.</span>
If<span> it is expressing the </span>recessive phenotype<span>, then </span>you know<span> right away what the</span>genotype<span> is. For </span>example<span>, for the </span>recessive<span> trait of green-colored peas versus the dominant trait yellow-colored peas. </span>If you<span> have green peas, then </span>you know<span> this plant has the homozygous </span>recessive genotype<span> for the pea color gene.</span>
