Answer:

The suitable option will be - A.

A.  lactose levels are high and glucose levels are low

Explanation:

  • Lac operon :

It is a operon that is regulated by a set of genes and is regulated altogether and is transcribed into a single RNA in the presence of lactose.

  • It is mainly found in  E.coli. Lac operon is mainly used for lactose metabolism. There are 3 genes in this system - lacZ, lacY, and lacA.
  • LacZ codes for β-galactosidase which cleaves lactose into glucose and galactose. LacY codes for Beta-galactoside permease, which helps in the entry of lactose in the cell. LacA codes for Galactoside acetyltransferase.

netineya [11]

Answer:

B. R is dominant to r, and Rr individuals are red.

Explanation:

In genetics the dominant allele is represented by the uppercase letter and the recessive allele is represented by the lower case letter. A dominant allele always shows its dominance over the recessive allele. So in heterozygous condition dominant allele will reflects itself in the phenotype.

Here allele of red color allele is in capital letter and alleles of green color are shown in lower case which means R allele is the dominant allele and r is the recessive allele. Therefore R is dominant to r and in homozygous condition(Rr) red individual will be formed. So the right answer is B.

Explanation:

Decreased fecundity.

Fecundity is nothing but the ability to reproduce.
