Before Darwin's Theory of Evolution, most people believed in Creationism.
True
False
A piece of evidence for evolution is the fact that embryos look very similar at the early stages.
True
False
John Ray began using Binomial Nomenclature to classify animals.
True
False
Darwin sailed the world aboard a ship called "Beagle".
True
False
Populations of species do not change over time.
True
False
Populations adapt to their environment through natural selection.
True
False
Jean-Baptiste Lamarck proposed that organisms
have an intense tendency toward complexity and perfection
have an innate tendency to become more simple as time passes
inherit all of the adaptations they display
belong to species that never change
When lions prey on a herd on antelope, some antelope are killed and some escape. Which part of Darwins concept of Natural Selection might be used to describe this situation?
acquired characteristics
survival of the fittest
reproductive isolation
descent with modification
According to Darwins theory of natural selection, the individuals that tend to survive are those that have
characteristics their parents acquired by use and disuse
characteristics that plant and animal breeders value
the greatest number of offspring
variations best suited to the environment
On the Galapagos Islands, Charles Darwin observed
completely unrelated species on each of the islands
species exactly like those found in South America
similar species with traits that suited their environment
species completely unrelated to those found in South America
Which of the following was NOT one of the adaptations discussed in the recent adaptations in humans assignment?
lactase persistence
sickle cell anemia
bitter taste perception
melanin levels
When two different alleles(genes) occur together, the one that is expressed is called:
dominant
recessive
phenotypic
superior
The law of segregation states that...
alleles of a gene separate from each other during gamete formation and each gamete can only receive one of the pair..
different alleles of a gene can never be found in the same organism.
each gene of an organism ends up in a different gamete.
each gene is found on a different molecule of DNA.
If two parents with dominant phenotypes produce an offspring with a recessive phenotype, then probably
both parents are heterozygous.
one parent is heterozygous.
both parents are homozygous.
one parent is homozygous.
In guinea pigs, black fur is dominant. A black guinea pig is crossed with a white guinea pig. If the litter contains a white offspring, the genotype of the black-haired parent is probably
homozygous dominant.
heterozygous.
homozygous recessive.
none of the above.
If an organism has 12 chromosomes in each body cell, how many chromosomes would you expect to find in the organism’s gametes (sex cells)?
4
6
10

Females
Equally in both
Who is considered the father of genetics?
Charles Darwin
Watson and Crick
Gregor Mendel
Albert Einstein
An inherited disorder is...
always fatal.
caused by an abnormality in an individuals DNA.
common.
rare.
Genetics is the study of heredity.
True
False
Genotype is the genetic makeup of an organism while phenotype is...
the noise the organism makes.
the entire genome of an organism.
the physical traits of an organism.
In punnent squares the dominant trait is represented by uppercase letters and the recessive trait is represented by lowercase letters.
True
False
Heterozygous means the alleles are...
different.
the same.
both dominant.
both recessive.
Incomplete dominance results in...
an organism that has no physical characteristics.
a genotype that is homozygous.
a phenotype intermediate between the dominant trait and the recessive trait.
Co-dominance occurs when...
both alleles for a gene are expressed in a heterozygous offspring.
neither allele for a gene is expressed.
Most sex linked traits are found on the X chromosomes.
True
False

Crossing over is
another opportunity for genetic variation.
when homologous pairs exchange genetic information.
All of the above
None of the above
In anaphase 1 of meiosis, do sister chromatids seperate?
Yes
No
Somatic cells are
