(1) Provide a general overview of Mendel's experiment.
Gregor Mendel developed the fundamental principals of
heredity. His experiments resulted in us knowing that genes,
carried on chromosomes are the basic functional units of
heredity with the ability to be replicated, expressed, or
mutated.
What was the organism that Mendel studied (provide the genus
and species name as well as the common name)?
The P plants that Mendel used in his experiments were each
homozygous for the trait he was studying. Diploid organisms
that are
homozygous
for a gene have two identical alleles, one on each of their
homologous chromosomes. The genotype is often written as
YY
or
yy
, for which each letter represents one of the two alleles in the
genotype.
Why was this organism ideal to study the law of independent
assortment?
the characteristics of seed color and seed texture for two pea
plants, one that has wrinkled, green seeds (
rryy
) and another that has round, yellow seeds (
RRYY
). Because each parent is homozygous, the law of segregation
indicates that the gametes for the wrinkled–green plant all are
ry

4. , and the gametes for the round–yellow plant are all
RY
. Therefore, the F1 generation of offspring all are
RrYy
List one dominant and one recessive example for a phenotype
that Mendel found and describe the phenotypic ratio expected to
result from crossing two parents heterozygous for only that
trait.
Observing that true-breeding pea plants with contrasting traits
gave rise to F1 generations that all expressed the dominant trait
and F2generations that expressed the dominant and recessive
traits in a 3:1 ratio
For the F2 generation of a monohybrid cross, the following
three possible combinations of genotypes could result:
homozygous dominant, heterozygous, or homozygous recessive.
Because heterozygotes could arise from two different pathways
(receiving one dominant and one recessive allele from either
parent), and because heterozygotes and homozygous dominant
individuals are phenotypically identical, the law supports
Mendel’s observed 3:1 phenotypic ratio.
In simple terms discuss gene transcription and translation.
What type of molecule results from translation? How do gene
transcription and translation lead to a specific phenotype?
Gene transcription and translation is expressing a gene means
manufacturing its corresponding protein, and this multilayered
process has two major steps. In the first step, the information in
DNA has transferred to a messenger RNA (mRNA) molecule by
way of a process called transcription. During transcription,
t
he DNA of a gene serves as a template for complementary base-
pairing, and an enzyme called RNA Polymerase II catalyzes the

5. formation of a pre-mRNA molecule, which is then processed to
form mature mRNA. The resulting mRNA is a single-stranded
copy of the gene, which next must be translated into a protein
molecule.
During the process of transcription, the information stored in a
gene's DNA is transferred to a similar molecule called RNA
(ribonucleic acid) in the cell nucleus.
