Asap in chickens, rose comb (r) is dominant over single comb (r). when a heterozygous rose-combed rooster is mated with a single-combed hen, what is the expected phenotypic ratio of the offspring?

The expected phenotypic ratio of the offspring would be

75% rose comb

AND

25% single comb

substitution is the answer in this case

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.
