ABC’s of Genetics
Ex. If one of PBR’s toughest bulls had the
dominant allele for brown hair and mated with
a cow that had the recessive gene for crème
hair they could have the following allele
possibilities:
2 brown alleles, BB (1 from mom,1 dad)
* Genotype is homo dominant
* Phenotype is brown hair
2 crème alleles, bb (both from mom)
* Genotype is homo recessive
* Phenotype is crème hair
1 brown and 1 crème, Bb (1 mom,1 dad)
* Genotype is hetero
* Phenotype is brown hair
Blending inheritance
Matt Mcadams
Chromosome: genetic information that you receive from either your mom or dad that makes up your DNA
Chromosomes tell what you’re going to look like, whether you will be a boy or a girl, and what kinds of disease you may get.
Chromosomes
are put into
karyotypes by
doctors to learn
about an
unborn baby
or an adult.

Dominant - The stronger of two genes expressed in the hybrid;
represented by a capital letter (R)

EX:fertilization occurs internally and so the eggs laid by the female are zygotes
Definition: A female reproductive cell.
Egg
Matthew osborne
The process in sexual
reproduction in which the
male and female
reproductive cells join to
form a new cell. Jonathan Dunn
F When both parents donate their genes to their child, resulting in offspring with a mix of inherited genes.
Genes Sequences of DNA that codes for a
protein and thus determines a trait. A factor that is passed from parent to
offspring.
genes control your eye color, blood group, height and even your IQ
Garrett Johnson
Definition: An
organism that is the offspring of two parents that differ in one or more inheritable characteristics, especially the offspring of two different varieties of the same species or the offspring of two parents belonging to different species.
H YBRID
EX: Blade the vampire slayer is a hybrid
between a vampire and a human. This happened because his mother was a human and she was bitten by a vampire so he had DNA of both human and vampire.
Incomplete Dominance • The letter that I was given is letter I.
• (Incomplete Dominance) – The gene for a condition is present, but not obviously expressed in all individuals in a family with the gene.
• Example :
• Graphic that illustrates the term.
Visual appeal.
Torey Woods
States that chance
determines which factor
for a particular trait is
inherited.
Dustin Messex
Law of segregation:
States that during the
formation of gametes,
pairs of genes for a
specific trait separate
so that offspring
receive one factor
from each parent.
Law of Independent Assortment:
Law of dominance:
States that one of the factors for a
pair of inherited traits will be dominant
and the other recessive, unless both
factors are recessive.
His research with garden peas led to the discovers of the basic principles of heredits.
He did a statistical study of traits in garden peas over an 8 year period.
After completing his work with peas, Mendel turned to experimenting with honeybees to extend his work to animals. Beaver Wheat.
Notation
When alleles are written as
subscripts
the capital T notates the dominant allele

Quintuplets are a result from a single fertilized
egg or zygote splitting in to five embryos. Each
carrying the same genes. Commonly called identical
or quints.
Ex: Other times when an egg splits it can split in to twins(2), triplets(3),
quadruplets(4) etc. Forming identical siblings as like above. Bonnie Dodd
A spermatozoon or an ovum; a cell responsible for transmitting DNA to the next generation.

The most common types of
autosomal trisomy that survive to
birth in humans are:
Trisomy 21 - (Down syndrome)
Trisomy 18 -(Edwards syndrome)
Trisomy 13 -(Patau syndrome)
Trisomy 9
Trisomy 8 -(Warkany syndrome 2)

We use it routinely to cure diseases, solve crimes, and reunite families. Yet we've known about it for only 60 years. And what we're continuing to learn about it every day has the potential to transform our health, our nutrition, our society, and our future.
Understanding Genetics: Genetics is the scientific study of heredity and it is the key to understanding what makes each organism unique.
V Visible
The phenotype
of a genotype is
the visible trait.
People who work with genetics: Doctors Geneticist
How do they work with genetics: • A geneticist is a biologist who
studies genetics, the science of genes, heredity, and variation of organisms. A geneticist can be employed as a researcher or lecturer. Some geneticists perform experiments and analyze data to interpret the inheritance of skills. A geneticist is also a Consultant or Medical Doctor who has been trained in genetics as a specialization.
CHROMOSOME
Carlie Yernest
The sex chromosomes carried by men; Human males normally have one x chromosome, and one Y chromosome.
• A zygote is the cell that is formed when the sperm cell fertilizes the egg cell.
• The zygote divides multiple times, producing identical copies of itself.
• The cells produced by the dividing of the zygote form the developing embryo, fetus, and baby.
