There is a difference in the number of alleles for hemophilia and red-green colorblindness, because when a carrier of protanomaly has a child with a deuteranomalic man. Denoting the normal vision alleles by P and D and the anomalous by p and d, the carrier is PD pD and the man is Pd. The daughter is either PD Pd or pD Pd. Suppose she is pD Pd. Thanks...
Through hydrogenation in the presence of the catalyst Pt/Pd/Ni .
Bi, Ni, Pd, Pt,Cu, Mn, Hg, Pb, Sn, Au, Ag, Zn, Cd, Fe, Sb
Pt and Pd can be used as catalyst in the hydrogenation of alkenes or (de)hydrogenation of hydrocarbons (cracking in petrol industry)
Copper (Cu), Silver (Ag), Rhodium (Rh), Palladium (Pd), Platinum (Pt), and Nickel (Ni) all are within the same area on the periodic table.

For example, platinum metals: Pt, Ir, Pd, Os, Rh, Ru.
Presumably, the Earth's core, which is believed to be made of molten Ni, Au, Pt, and Pb.
For example platinum group of metals: Pt, Ir, Os, Pd, Rh, Ru.
