In a few sentences, summarize Darwin’s theory of natural selection. Your Answer: that too many offsprings were produced than an environment could support would lead to offspings without desirable traits would not survive versus the ones with the desireable traits in the environment.

Question 3 6 / 6 pts

Are preformation and epigenesis the same thing? Explain why or why not. Your Answer: no they are not the same because epigenesis contradicts preformation in which by epigenesis meaning a fertalized human egg undergoes a specific developmental events that leads to human formation while preformation means fertilized eggs contained a small version of a completly developed adult Preformation postulated that a fertilized egg contained a miniaturized version of a tiny human. Epigenesis directly contradicted that theory by stating that a fertilized egg undergoes a series of developmental events that eventually form a human.

rrect Answe Correct! Correct! Genes, contributed from each parent, are carried on chromosomes. The proteins within chromosomes are the chief drivers of genetic inheritance Chromosomes inherited from a father will be dominant over those from the mother.
