Organisms that have two different alleles for a trait are called
What is hybrid or heterozygous
200
These are factors that control traits

200
These are different forms of a gene
What are Alleles
200
A trait that will ALWAYS show up in an organism as long as it it present
What is a dominant allele
200
A trait that is masked by a dominant allele
What is a recessive allele

This is a chart that shows and arranges chromosomes in order from largest to smallest
What is a Karyotype
300
This refers to an organisms genetic make up

300
This refers to an organism's Physical Characteristics
What is a Phenotype
300
This is a chart used to find all possible allele combinations in a cross.
What is a Punnett Square
300
This is having two DIFFERENT alleles for a trait
What is heterozygous
300
This is having two IDENTICAL alleles for a trait
What is homozygous
400
This is when two alleles are both dominant
What is co dominance
400
Referred to as the "genetic blueprint" or code for an organism
What is DNA
400
This brings the code from the nucleus to the ribosome
