The gene that produces the enzyme placental alkaline phosphatase in humans starts at position 232 million on chromosome 2 (which is 242 million bp long). a. Draw a single copy of chromosome 2 in un-replicated form (one chromatid). Note that chromosome 2 is submetacentric (centromere is near the middle, but closer to the beginning). Indicate the location of the placental alkaline phosphatase (PLAP) gene.
b. PL4P has two common alleles, let's call them. P. and Pz. Draw your homologous chromosome 2 pair assuming you have one copy of both alleles.

The correct answer is iron.

Explanation:

Iron is required to produce red blood cells, which transport oxygen all through the body. At the time of pregnancy, one requires more iron as the volume of the blood enhances and the development of baby's blood also takes place.  

In order to include more iron in the diet, one should comprise at least two servings of chicken, meat, legumes, fish, and nuts each day. One should consume cereals, whole-green bread, and green leafy vegetables regularly. In the case of certain women who are not able to get adequate amount of iron from the food, they need to get an iron supplement.
