! I did not know that the
location of the mutation in the genome can affect an individual. For example,
how if the mutation is located in the protein coating of the genome that it
could be dangerous to the person! I found this quite interesting.

? I don’t think that I really
understand how to get the allele frequency. Reflecting to the book, it says
to take the numbers of alleles in a population and divide by the total number
of alleles. I provided an example that I made up that kind of explained it to
me.
 
 

Phenotype
variations are the physical genetic
characteristics that all humans along with other species have. Some examples
of phenotype variations is eye and hair colors. There are two factors of a
phenotypes. The first one is the genotype, which is your alleles. The second
factor of phenotypes is the environment of the species. Although with humans,
we tend to have different characteristics and phenotype variations, and we
have the lowest variation opposed to other animals and species. For instance,
if you take and compare two human’s genes, their genomes are 99.9% alike. There
are many different types of species. Species
can share and reproduce genes with another species. These species receive
their genetics from a gene pool that
contains alleles that control our hair color, eye color, skin color and many
more. Populations are all the
species that share genetic information in the same environment. There are two
different genetic variations. One is mutations. Mutations make a new variation in alleles. Mutations can be somatic which takes place in the body
tissue. This mutation will only affect the person where the mutation began at
unlike germ-line. This is genetic
and can be passed down to the next generation. The second source of genetic
variation is recombination which
switches up the alleles in mutations and creates a new variation. Mutations
can also ne neutral where they do
not affect an individual because it takes place in a non-coding DNA in the
genome of the individual. A mutation can be dangerous if the mutation effects
the protein part of a genome which makes it deleterious. A mutation that could be useful for an individual
would be advantageous. An
advantageous mutation has it’s advantages, one of them being that the species
can still reproduce although it has a mutation. Allele Frequency is the frequency of alleles in the population. It
is how often we see this allele in genetics. To get a total number of
alleles, you take the number of alleles that are in a population than you
divide that by all of the alleles total. For example, if there was a pea
plant that is white and both dominant Ww and a pea plant that is purple and
is recessive ww, then it will have 50% Ww and 50% ww. The offspring have a
half and half chance of either getting the dominant or recessive traits.
