heredity Flashcards
the passing of genetic material from genetic material from parents to offspring
heredity
segments of DNA found in chromosomes that give instructions for producing a certain characteristic
genes
different versions of the gene
allele
the combination of alleles that you inherit from your parents
genotype
your obsevable traits
phenotype
allele contributes to the phenotype if one or two copies are present in the genotype
dominant
allele contributes to the phenotype only when 2 copies of it are present
recessive
each allele in a heterozygous individual influences the phenotype
incomplete dominance
both of the alleles in the heterozygous individual contributes to the phenotype
codominance
a characteristic passes from one generation to another
trait
graphic used to predict possible genotypes to offspring
punnett square
example of incomplete dominance
when a red flower breeds with a white flower and makes a pink flower
example of Codominance
when someone with type A blood breeds with someone with type B blood their offspring will have AB blood type
