Heredity and Genetics Flashcards
What is Heredity?
the passing of traits from parent to offspring.
What is Genetics?
The study of how traits are inherited.
What are Genes?
The material that controls which traits are expressed in an organism.
Note Card
Genes come in pairs and offspring inherit one copy of each gene from each parent.
What are Alleles?
the different forms o a trait that a gene may have
What is Characteristic?
A feature that has different forms
What are traits?
The different forms of the characteristics.
A trait that prevents another trait from appearing.
Dominant Trait
A trait that does not appear when the dominant trait is present.
Recessive Trait
- receives different genetic information for a trait from each parent.
- is a trait that is made up of a combination of a dominant and recessive trait
Hybrid/ Heterozygous
An organism with two different alleles for one trait ( Tt )
Heterozygous ( hybrid )
- receives the same genetic information for a trait from each parent
- it is a trait that is made of all dominant or recessive traits.
Pure ( Dominant/Recessive )
An organism with two alleles for one trait that are the same written TT for pure dominant or tt for pure recessive
Homozygous
the genetics make-up of an organism
genotype
the way an organism looks as a result of its genotype.
