inserting working copies of a gene directly into the cells of a person with a genetic disorder is called
Gene therapy
The different forms of a gene are called
Alleles
the passing of physical characteristics from parents to offspring
heredity
These carry amino acids to the ribosomes
Transfer RNA
This can cause a cell to produce an incorrect protein
Mutation
Process of selecting a few organinsms with desired traits to serve as parents is called
Selective Breeding
Having two recessive alleles (aa) is called
homozqygous recessive
The crossing of two individuals that have similar characteristics
Inbreeding
The transfer of genes from one organism to another is called
Genetic engineering
An organism with two different alleles for a trait
hybrid
A(n)_______________ is all the DNA in one cell of an organism.
genome
The scientific study of heredity is called
genetics
The combination of alleles that code for trait is its what?
genotype
A chart that shows all the possible combinations of alleles is a
Punnett square
What is it called when both alleles are expressed?
codominance
The physical trait that appears in an organism is its
phenotype
A person who has one recessive and one dominant allele for a trait is called
carrier
An abnormal condition that a person inherits through genes or chromosomes is a
Genetic Disorder
When chromosome pairs seperate and are distributed to two different cells is
Meiosis
Factors that control a trait are called
genes
a number that describes how likely it is that an event will occur
Probability
Recessive traits are represented by what type of letter
lower case
this person experimented with pea plants
Mendel
These are made up of many genes joined together
Chromosomes
Having two of the same alleles like AA or aa is called
homozygous
