Upon careful examination of the offspring obtained from your cross, it was determined that only 25 offspring were double crossover phenotype -- half of the 50 that was expected. now, how many offspring that represent a single crossover event between pr and vg are expected, considering that positive interference has occurred? express your answer as a whole number.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
