allele
Definition
a specific version of a gene
Term
genotype
Definition
the alleles are present in an organism
Term
phenotype
Definition
the appearence or condition of the organism caused bt the alleles
Term
homozygous
Definition
having two allels that are the same
Term
heterozygous
Definition
having two allels that are different
Term
dominant
Definition
when there are two different alleles determines the different phenotype
Term
mendels law of independent assortment

are genes for differnet characteristics are inherited independently
Term
gentics
Definition
the study how charactertics are inherited

law of segreation
Definition
deals with how alleles are passed from parent to offspring
