traits | characteristics that varied from one organism to the next |
true breeding strains | the parental generation w/ no other traits/genes |
p generation | parental generation |
f1 generation | 1st filial generation |
blending hypothesis | offspring is a mixture of both |
hybrids | offsprings of parents who have different traits |
genes | inheritance of traits |
allel | a variation of a gene |
law of dominance | some alleles are dominant and others are recessive |
law of segregation of alleles | the gamete carries a copy of a gene as it separates in meiosis |
homozygous | 2 identical alleles for particular trait |
phenotype | physical appearance/function |
