EXAM 2 GENETICS PORTAGE LEARNING
STUDY GUIDE PAPER 2026 QUESTIONS
WITH CORRECT SOLUTIONS GRADED A+
⩥ What were domesticated wolves used for and what did it evolve into?
Answer: Used for hunting, evolved into breeds that were used for a wide
variety of uses (herding, guarding, retrieving, tracking, companion)
⩥ What does selective breeding and environment do? Answer: Induce
diversity
⩥ The understanding of human genetics started with Answer: William
Harvey and his proposal of epigenesis
⩥ preformation Answer: fertilized egg contains a tiny version of a
completely developed adult term homunculus
⩥ epigenesis Answer: concept that hypothesized that a fertilized human
egg undergoes specific developmental events that lead to the formation
of a human
⩥ early theories proposed that the fertilized egg contained a tiny human
in a form called the Answer: homunculus
, ⩥ spontaneous generation Answer: the idea that living things can
spontaneously generate from nonliving components
⩥ what theory debunked spontaneous generation Answer: cell theory
⩥ cell theory Answer: correct theory that all living things are composed
of organized structures called cells derived from precursor cells
⩥ Theory of Natrual Selection Answer: more offspring produced than an
environment can support therefore only the strongest will survive, adapt,
and evolve; leads to struggle for survival so offspring would only inherit
the most desirable traits for their certain environment to survive
⩥ How does natural selection apply to humans now that we no longer
need to fight for survival? Answer: Will still acquire random mutations...
gene that allows us to digest lactose arose from people domesticating
animals and drinking there milk as a result we were able to tolerate it
⩥ modern genetics Answer: the study of heredity; the understanding of
genes and how they contribute to the passing of traits; a gene has a place
on each chromosome and knows exactly where it needs to be and when
⩥ chromosomal theory of genetics Answer: both heredity and
development depend on the passing of genetic information via genes
contained within chromosomes
