EXAM 2 GENETICS PORTAGE LEARNING
ACTUAL TEST PAPER 2026 QUESTIONS
WITH ANSWERS GRADED A+
⩥ 1.1 Epigenesis and performation. Answer: The understanding of
human genetics beyond selective breeding increased in the 1600s when
William Harvey, a development specialist, proposed epigenesis.
it was a concept that a fertilized human egg undergoes specific
developmental events that eventually lead to the formation of a human
At the time, this theory directly contradicted the idea of preformation, in
which a fertilized egg contained a tiny version of a completely
developed adult termed a homunculus
⩥ 1.1 cell theory. Answer: it was introduced by Matthias Schleiden and
Theodor Schwann, proposing that all living organisms were composed
of organized structures called cells and that these cells were derived
from identical precursor cells.
⩥ 1.1 spontaneous generation. Answer: The idea that living things can
spontaneously generate from nonliving components (dust can become
fleas)
, ⩥ 1.1 Natural selection. Answer: theory made by Charles Darwin
More offspring are produced then an environment can support the
strongest will survive in
Survival in a crowded environment would lead to struggle within a
population, so the offspring that inherited the most desirable traits for a
certain environment would ultimately survive
EXAMPLE: in a mountain environment, animals that were well-adapted
for climbing steep cliffs or surviving harsh winters would survive much
longer than those that had difficulty balancing on rough surfaces or that
possessed a thin outer covering.
⩥ 1.2 genetics. Answer: defined as the study of heredity, was first coined
in the early 1900s and focuses primarily on the understanding of genes
and how they contribute to the passing of traits
⩥ chromosomal theory of inheritance. Answer: introduced in the 1910s
by showing that both heredity and development depended on the passing
of genetic information via genes that were contained within
chromosomes
These chromosomes were ultimately proven to be equally contributed
from each parent via gametes
