Question

describe how advances in genetics have influenced our understanding of the emergence of new species. (dok 3)
advances in genetics have shown how mutations and genetic variation lead to the emergence of new species, changing our understanding of how life evolves over time.
genetics has no impact on our understanding of evolution and has not impacted our understanding of evolution.
genetics has only helped scientists understand plant growth, changing our understanding of how life evolves over time.
genetics is only used to study extinct species, changing our understanding of how life evolves over time.

Explanation:

Genetics studies genes and heredity. Mutations create genetic variation. New species form when populations with enough genetic differences can't interbreed. So, genetics (via mutations and variation) shows new - species emergence. The second option is wrong as genetics clearly impacts evolution understanding. The third option is incorrect as genetics isn't only about plant growth. The fourth option is wrong as genetics isn't only for extinct species.

Answer:

Advances in genetics have shown how mutations and genetic variation lead to the emergence of new species, changing our understanding of how life evolves over time.
