Answer:

Phenotypic ratio - 3 Freckes : 1 No freckles

Explanation:

This question represents a monohybrid cross i.e. involving a single gene coding for possession or not of freckles. The allele for possession of freckles (F) is dominant over the allele for no freckles (f).

In a cross between two HETEROZYGOUS parents i.e. Ff × Ff, each parent will produce gametes with alleles F and f respectively. Using a punnet square (see attached image), four possible offsprings will be produced with genotypes: FF, Ff, Ff and ff.

Based on this genotypes, the phenotypic ratio of the offsprings will be 3:1 where 3 offsprings will possess freckles and 1 will have no freckles.

Answer: Sugar metabolism , DNA replication and lipid synthesis.

Explanation:

The pathways or the phenomenon is very fundamental that takes place in all the living organisms.

These processes are fundamental to life and is vital for the growth and development of the organism. The cell proliferation and growth is also very essential in case of bacteria.

hence, these processes are highly conserved from one species to another species.
