Answer: The given question is not true and false it has some of its missing. It has missing blanks at the place storage protein ferritin and transport protein called transferrin.
Explanation:
If is difficult the iron inside the body. It is ingested by the food that we eat. The iron is stored in the body in the mucosal cells.
The iron inside the body is made to store in the mucosal cells by the help of iron storage protein called ferritin.
The mucosal cells of the intestine sheds after every 3 or 4 days. In case the stored iron in the body is not utilized it is shed along with the mucosal cells of the body.
Hence, the given statement is True.
Answer: It occurred a dihybrid cross and epistasis.
Explanation: In dihybrid cross, two different genes controlled two different traits. When they interact with each other is called Epistasis. However, in wheat plants, the genes related to color kernels don't act opposedly to each other. In other words, the genes have the same role in producing protein, so they can substitute for each other.
In the color determination mechanism, a biochemical reaction is necessary to convert a precursor substance into a pigment and that reaction happens with the product of either genes. That's why having a dominant allele makes the wheat colorful. So, crossing colored kernels with white ones will produce a heterozygous F1 generation. Crossing this generation will produce a F2 generation with modified ratio of 15 colored: 1 non colored because, every individual who has dominant alleles will produce the substance and thus the biochemical reaction will happen. Only recessive homozygous ones won't have the substance and so won't have color.
