law of independent assortment
the alleles for different traits will immediately separate from each other in gametes
what is the difference between gene and an allele
a gene is specific part of DNA that codes for a trait when an allele is the specific variation of the gene you receive from your parents`
gene
specific segment of DNA that codes for a trait
allele

law of dominance
some alleles are dominant over recessive alleles and will be shown over the recessive alleles
law of segregation
alleles will separate from each other during the gamete formation

what is a gamete
sex cell, egg or sperm
what is the difference between incomplete dominance and codominance
codominance- shows both COSHOBO
incomplete dominance- a mix
