What does the Mendelian principle of segregation state?
Alleles are selected based upon the offspring.
Each parent’s alleles stay together.
One allele from each parent is passed on to the offspring.
The offspring genes are segregated from the parent during conception.
In order for a heterozygous trait to be expressed in a phenotype of an animal, what type of gene must it be?
Dominant
Recessive
Sex linked
Recombinant
Different genes are passed on to offspring independently of each other. This is part of the principle of what?
Segregation
Independent assortment
Units
Recessive traits
What is inheritance?
Mitosis that occurs in animals
The crossing over of traits in meiosis
Traits that are expressed through the sex of the animal
The passing on of traits from parent to offspring
What is an allele?
The gene that is physically expressed in an offspring
The form of a gene that expresses a trait
The trait that is not passed on by the parent
A recessive trait

What is one cause of mutations?
Exposure to radiation
Vitamin deficiencies
Feeding animals genetically modified foods
Cloning
How are new variations in offspring DNA formed?
Through neoplasia
By embryo splitting

An animal that shows the characteristics of a specific breed of animal is called a/an what?
Hybrid
Sire
Dam
Purebred
What process drives natural selection?
Evolution
Microevolution
Survival of the fittest
Extinction
Which types of species are most likely to become extinct?
Those that have lots of variation
Those that have small gene pools
Those with a large number of individual organisms
Those that are spread out throughout the world
What is one of the major processes that add genetic variation to purebreds?
Mutation
Crossbreeding and backcrossing
Genetic Isolation
Genetic Drift
Why is the gene pool isolated for purebred animals?
They are physically incompatible to mate with different animals.
Geographic isolation limits the gene pool.
They don’t have the same number of chromosomes, so the babies die.
Registries do not accept animals which do not have both parents in the registry.
