Genetics Final Exam
Tests With Correct
Solutions.
who proposed epigenesis - correct ans:William Harvey
A concept that is now known to have correctly hypothesized that a fertilized
human egg undergoes specific developmental events that eventually lead to
the formation of a human. - correct ans:Epigenesis
A concept that a fertilized egg contained a tiny version of a completely
developed adults. - correct ans:Preformation
In preformation, the tiny fully sized adult within the fertilized egg is termed -
correct ans:homunculus
Who proposed the cell theory? - correct ans:Matthias Schleiden and Theodor
Schwann
Proposed that all living organisms were composed of organized structures
called cells and that these cells were derived from identical precursor cells. -
correct ans:cell theory
the concept that livings things could spontaneously generate from nonliving
components - correct ans:spontaneous generation
Who proposed natural selection? What does it entail? - correct ans:Charles
Darwn; The origin of species; natural selection believed that more offsprings
were produced than an environment could actually support. Suvival in a
crowded environment would allow only the strongest to survive.
, What is an example of natural selection? - correct ans:For instance, 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.
Who proposed published work on pea plants? - correct ans:Gregor Mendel
Is natural selection still prominent in todays society? - correct ans:Yes, We
still acquire random mutations that sometimes become "normal". An
example of that is the gene that allows us to digest lactose. When mammals
(humans included) cease breastfeeding, it is normal for them to stop making
lactase, an enzyme that digests milk.
defined as the study of heredity and was first coined in the early 1900s and
focuses primarily on the understanding of genes and how they contribute to
the passing of traits. - correct ans:genetics
By the 1910s, the _____________ was introduced, showing that both heredity
and development depended on the passing of genetic information via genes
that were contained within chromosomes. - correct ans:chromosomal theory
of inheritance
units of heredity which are transferred from a parent to offspring and are
held to determine some characteristic of the offspring - correct ans:genes
are found in the nucleus of a cell and hold the genetic information for almost
all living organisms. - correct ans:chromosomes
Each organism carries a specific number of chromosomes, called the -
correct ans:diploide number (2n)
