A group of similar organisms that can mate with each other and produce fertile offspring.
Species
Differences between members of the same species are called this.
Variations
Only traits controlled by these can be acted on by natural selection.
Genes
A species that no longer has any living members is said to be this.
Extinct
A term that refers to similar structures that related species have inherited from a common ancestor.
Homologous structures
Gradual change in a species over time
Evolution
A trait that helps an organism survive and reproduce is called this.
Adaptation
What term refers to the process by which individuals that are better adapted to their environment are more likely to survive and reproduce.
Natural Selection
This person cross-pollinated plants to study different characteristics in her or his genetic experiments.
Mendel
Factors that control traits are called this.
Genes
An organism that has two different alleles for a trait is called this.
Hybrid
If T is dominant for tall and t is recessive for short, what will the following allele combination express?

Tt
Tall
An organisms physical appearance is its this.
Phenotype
This theory states that genes are carried from parents to offspring on chromosomes.
Chromosome theory of inheritance
A term that refers to physical characteristics studied in genetics.
Triats
The different forms of a gene are called this.
Alleles
An organism's genetic makeup is its this.
Genotype
An organism that has two identical alleles for a trait is this.
Homozygous
These are made up of many genes joined together.

Boy or Girl?


XX
Girl
This is a chart that tracks which members of a family have a particular trait.
Pedigree
This is know as a picture of the chromosomes in a cell.
Karyotype
This is known as all the DNA in ne cell of an organism.
Genome
These genes are genes on the X and Y chromosomes.
Sex linked genes
This term describes a person who has one recessive and one dominant allele for a trait.
Carrier
This disorder can cause internal bleeding of the joints, which can lead to arthritis.
Hemophilia
Common symptoms from this disorder include smelly and greasy stool, salty skin, and chronic coughing.
Cystic fibrosis
Common symptoms from this disorder include mental retardation and decreased muscle tone.
Down Syndrome
Vast majority of people with this disorder carry an extra copy of chromosome 21 in every cell of their body.
Down Syndrome
This disorder can be cured with a bone marrow trasplant.
Sickle cell
The forelimbs of a bird and a mammal are example of this.

Hemophilia
The function of this organ is to deliver oxygen to and remove carbon dioxide from your blood
Lungs
Pumps oxygen-rich blood throughout your body and oxygen-poor blood to your lungs
Heart
Carry oxygenated blood away from the heart
Arteries
Carry deoxygenated blood to the lungs
Veins
Produce eggs
Ovaries
Produce sperm
testes
Makes urine from waste products and excess water found in your blood
Kidneys
Gets rid of toxins, to regulate your blood sugar levels and to produce bile
Liver
Convert food waste products into feces
Large intestine
Secretes digestive enzymes and hormones that control blood sugar levels
Pancreas
Responsible for the chemical digestion of food and absorption of nutrients into your blood
Small intestine
This organ is about 5 meters long
Small intestine
This is where gases diffuse from your lungs into your blood and from your blood into your lungs.
Alveoli
How many chambers does the human heart have?
4
Largest organ
Skin
Age is the major risk factor with this disorder. Symptoms include memory loss, confusion, anxiety and insomnia. There is no obvious pattern of inheritance
Alzheimer’s Disease
According to another theory, species evolve during short periods of rapid change.
punctuated equilibria
According to one theory, evolution occurs slowly but steadily. Tiny changes in a species gradually add up to major changes over very long periods of time.
gradualism
This scientist's mportant observations included the diversity of living things, the
remains of ancient organisms, and the characteristics of organisms on the Galápagos Islands.
Darwin
Human height is an example of this type of variation.
Continuous
Skin color is an example of this type of variation.

Hemophilia
This term means that a trait is influenced by environmental as well as genetic factors.
Multifactorial
These carry deoxygenated blood to the heart
Veins
These carry oxygenated blood away from the heart.
Arteries
This organ gets rid of toxins, to regulate your blood sugar levels and to produce bile for fat digestion.
