The study of hereditary traits and how they are inherited.
What is genetics
100
The law states that all inherited traits are determined by genes.
What is the law of inheritance
100
The form of a hereditary trait in which one allele is dominant and determines that trait.
What is dominant inheritance
100
A permanent change that occurs in DNA.
What is mutation
100
An area of genetic engineering that involve replacing defective genes with health ones.
What is gene therapy
200
The transfer of traits or characteristics from one generation to the next.
What is heredity
200
The set of alleles of a gene that an organism inherits.
What is genotype
200
A type of inheritance in which one allele is hidden when passed to an offspring but is not exhibited in the presence of the dominant form of the trait.
What is recessive inheritance
200
A mutation that occurs when DNA is not copied correctly or when pieces of DNA are lost or gained.
What is a gene mutation
200
A process that involves transferring the genes from one organism to another organism.
What is genetic engineering
300
The form of a hereditary trait that always seems to be visible.
What is dominant
300
An organism's physical appearance created by one or more genes.
What is phenotype
300
A condition in which neither allele of a gene pair is dominant or recessive. This condition results in a blending of traits.
What is incomplete dominance
300
A mutation that occurs when a chromosome breaks and pieces are lost, new pieces are gained or the original pieces join in a new way.
What is chromosome mutation
300
A process that involves the purposeful selection of parents with desirable characteristics in order to produce more desirable varieties of plants and animals.
What is selective breeding
400
The form of a heredity trait what is hidden by the dominant form of the trait.
What is recessive
400
A gene made of alleles of the same form.
What is homozygous
400
A scientist who specializes in the study of heredity.
What is a geneticist
400
An inherited disease caused by a chromosome mutation.
What is genetic disease
400
Genetic engineering has produced disease and rot-resistant plants, proteins and enzymes, insulin, and interferon. It has also been used to fight various diseases, including DNA.
What is the impact of genetic engineering
500
The first person to identify specific traits and describe how they were inherited.
Who is Gregor Mendel
500
A gene made of alleles of various forms.
What is heterozygous
500
An organism that carries a recessive trait but does not exhibit the trait.
What is a carrier
500
-DNA is not copied correctly
-Pieces of DNA are lost or gained
-A chromosome breaks and pieces are lost
