The Answer is B) Bilateral Symmetry
Answer:
AB, Ab, aB, ab.
Explanation:
Crossover may be defined as the process of exchange of the genetic material between the non sister chromatids of two homologous chromosomes. This process occurs at the prophase I of meiosis.
The one chromosome carries A and B genes and the homologous chromsome carries same genes, a and b. The single cross over has occur so two parental gametes are formed (AB, ab) and two gametes are recombinant (aB and Ab).
Thus, the answer is AB, Ab, aB, ab.
The superficial palmar arch<span> is formed predominantly by the </span>ulnar artery<span>, with a contribution from the </span>superficial palmar branch of the radial artery<span>. However, in some individuals the contribution from the radial artery might be absent, and instead anastomoses with either the </span>princeps pollicis artery<span>, the </span>radialis indicis artery<span>, or the </span>median artery<span>, the former two of which are branches from the radial artery.</span>
