would not accept my question the way I stated it, so I took a screenshot of it. Can someone please answer it for me and explain it?

Suppose A is the dominant allele and a is the recessive allele. the homofzygous dominant genotype will be AA and the fheterozygous will be Aa.

Let's make the Punnet square and we find the combinations of alleles deriving from the crossing:

AA, AA, Aa, Aa

The probability of having a homofzygous recessive child is therefore 0%

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !

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.
