Answer:

The statement is false.

Explanation:

At the base of the oxyntic gland, in addition to the parietal cells, the chief cells (peptic cells) are located, mainly in the lower half of the gastric glands, these cells have large basophilic zymogen granules, more prominent in the apical region and responsible of the secretion of pepsinogen proteolytic enzymes, a relatively constant fraction of pepsinogen I released by the chief cells is absorbed by the blood instead of passing into the gastric lumen. The stomach acid transforms pepsinogen into pepsin, which breaks down proteins in food during digestion.

having free earlobes is a dominant trait in humans, and having attached earlobes is recessive. a father has the genotype ff, and

k0ka [10]

A phenotype is a physical characteristic which is visible. Hence when the resulting combinations have two dominant alleles or even one dominant allele, the dominant characteristic is exhibited. The recessive characteristic is exhibited only when both the alleles are recessive.

To find the ratio of phenotypes, we need to place the genotype of the father and mother in a grid form ( attached grid figure)

Here we have two Ff phenotypes which is dominant and two ff phenotypes which is recessive

Hence the ratio is 2:2 or 1:1
