Question

E. coli bacteria are haploid, contain a single chromosome and divide asexually. Based on this information, which of Mendel's realizations/laws is the only one applicable to E. coli bacteria?

a. Law of dominance

b. Law of independent assortment

c. Law of segregation

d. Organisms contain two copies of the heritable factors

e. Traits are passed on as heritable factors

Answer 1

E is the answer.

Explanation:

According to law of dominance, when there are found two homologous chromosome, then one allele on one homologous chromosomeis dominant over another allele on other homologous chromosome. but in case of e coli there is found single chromosome due to which the law of dominance is not applicable.

When there is found two genes assorted independently due to presence of homologous chromosome. Hence the single chromosome in E. Coli don't obey law of independent assortment.

The two alleles of a gene is not found in E. coli. Thats why law of segregation is not found in E. coli because of single chromosome.

There are not found two copies of alleles in E. coli.

E answer is right. Because the chromosome is passed from the one bacterial cell to another during the process of amitosis.
