<span>Intrinsic factor is a glycoprotein principally secreted by the parietal cells of the stomach. This secretion is needed to produce mature erythrocytes. Its secretion is governed by the same biochemical processes that regulate acid secretion and its action is to assist in the absorption of vitamin B12.</span>

Explanation:
As we know that different versions of the gene are called as the alleles. Allele is the various sequence of DNA (deoxyribonucleic acid) or alleles are known to be different forms of the genes, which can be seen at the same locus on the homologous chromosomes. Let us know assume that gene Tyx has two alleles in it, which represents the two forms of expression having same character. i.e. Tallness and Dwarfness TT(tall), Tt(tall), tt(dwarf). In the given question, the version
(a) TT, where alleles exist in the homozygous dominant conditions,
(b) Tt, where alleles exist in the heterozygous dominant condition
(c) tt, where alleles exist in homozygous recessive condition. Therefore, it might follow autosomal dominant inheritance, or autosomal recessive inheritance or incomplete dominance etc.
Answer:
Function and location The plasma membrane H+ - ATPase or proton pump creates the electrochemical gradients in the plasma membrane of plants, fungi, protists, and many prokaryotes. Here, proton gradients are used to drive secondary transport processes.
