Koch's postulates are the four criteria established by Robert Koch, the founder of modern bacteriology,  to identify the causative agent of a particular disease.  These four postulates are:
1. The microorganism or other pathogen must be present in all cases of the disease.
2. The pathogen can be isolated from the diseased host and grown in pure culture.
3. The pathogen from the pure culture must cause the disease when inoculated into a healthy susceptible laboratory animal.
4. The pathogen must be re-isolated from the new host and shown to be the same as the originally inoculated pathogen.

If obesity is dominant and designated as "O" and thinness is recessive and designated as "t," how many of the following individu
OlgaM077 [116]

Answer:

b. ​3

Explanation:

Dominant genes are represented by capital letters (such as the "O" used to show that the obesity gene is dominant) and phenotypically expressed as heterozygosis (Ot) or homozygosis (OO). These genes are those that determine a hereditary trait even when in single dose genotypes. That is, they determine their character even in the absence of their dominant allele.

Recessive genes are represented by lowercase letters (such as the "t" used to show that the thinness gene is recessive) where phenotypes are expressed only in homozygosis (tt). Thus, only the individual who presents tt genes, among the options given in the question, will not present obesity.

Gilligan represents the only person who does not have the "O" allele, his alleles are "tt", so Gilligan will not be obese. However, Ginger, who is "OO", Mary Ann, who is "Ot" and Thurston, who is "tO", have the dominant allele responsible for obesity, so from the options given, we can say that 3 individuals have the highest probability to be obese.
