Mendel's Law of Biology

Monohybrid cross

• this cross is used when studying one trait

• this cross is used when studying two traits

• this cross is used when studying three or more traits

genes

• the allele combination of an organism

• different forms of genes

• alleles for traits are the same

• factors that determine traits

phenotype

• factors that determine traits

• every organism has two alleles which separate when gametes are produced

• genes for different traits are inherited independently of each other

• the way an organism looks and behaves

homozygous

• the allele combination of an organism

• different forms of genes

• alleles for traits are the same

• factors that determine traits

heterozygous

• this cross is used when studying one trait

• this cross is used when studying two traits

• this cross is used when studying three or more traits

• when two alleles for a trait are different

dihybrid cross

• this cross is used when studying one trait

• this cross is used when studying two traits

• this cross is used when studying three or more traits

• when two alleles for a trait are different

Law of Independent Assortment

• every organism has two alleles which separate when gametes are produced

• alleles for traits are the same

• genes from different traits are inherited independently of one another

• the allele combination of an organism

Law of Segregation

• every organism has two alleles which separate when gametes are produced

• alleles for traits are the same

• genes from different traits are inherited independently of one another

• the allele combination of an organism
