Answer 2

The correct answers are as follows:

Explanation:

• i) Speciation or Evolution.

New species develop by the accumulation of numerous mutations in the genome over a long time period. These mutations mostly benefit the organisms by helping them adapt to changes in environmental conditions.

• ii) Genes

Qualitative and quantitative characteristics of the parents are transmitted to the offspring through genes.

• iii) Alleles

Alleles are different forms of any one gene that encode for different characteristics of the same gene.

• iv) Flatworm.

They belong to the Phylum Platyhelminthes and possess incompletely developed eyes.

• v) Chromosome.

These thread like structures coil and condense to form the Chromatin Structure.
