Hydrogen bonds<span> are much weaker than covalent bond because of its bond is formed through fundamentally electrostatic interactions.
Hydrogen bonds happen due to dipole-dipole attraction while covalent bonds happen when valence electrons are shared.
Reasons why complementary nucleotides across the double-stranded dna bond together using hydrogen bonds rather than covalent bonds are (1) the distance between two strands, (2) size of the bases, (3) geometry of each base.</span>

Answer:
1/3
Explanation:
<em>A standard monohybrid cross is a cross that follows the dominance/recessive pattern from Mendel's experiment.</em>
It means the purple flower color is dominant over the white flower color.
Assuming the allele for purple flower color is P and that of the white flower color is p, a standard monohybrid cross will involve a true breeding PP and pp.
PP x pp: Pp, Pp, Pp and Pp. All the F1 offspring will have purple flowers with Pp genotype.
At F2: Pp x Pp = PP, Pp, Pp, and pp.
3/4 or 75% of the F2 offspring have purple flower color out of which 1 is true breeding for the trait.
Hence the fraction of the purple flowered peas in the F2 that is expected to be true-breeding (PP) is 1 out of 3.
