What is a Gamete?
A reproductive diploid cell with half the normal number of chromosomes
What is a Chromosome?
A long strand of DNA that holds genetic information in the form of genes
What is a Gene?
A sequence of DNA that codes for specific sequences of amino acids to make proteins
What is an Allele?
Different versions of the same gene
What are Dominant and Recessive alleles?
Dominant alleles are expressed in the phenotype all the time Recessive alleles are only expressed if 2 of the same allele is present
What is Homozygous?
When a person has 2 of the same allele for a trait
What is Heterozygous?
When a person has 2 different alleles for a trait
What is a Genotype?
The genetic makeup of an organism, eg. BB or Bb
What is a Phenotype
The characteristic that is expressed as a result of the genotype, eg. Brown or blue eyes
What is a Genome?
The entire genetic code/material for an organism.
