Question | Answer |
---|---|
different forms of a gene | allele |
genetic cross comparing two traits | dihybrid |
an allele that masks other alleles | dominant allele |
offspring of the parental generation | F1 generation |
offspring of the F1 generation | F2 generation |
joining of male and female gametes forming a diploid cell | fertilization |
haploid sex cell produced through the process of meiosis | gamete |
a segment of DNA that codes for a particular trait (or protein) | gene |
study of heredity | genetics |
the genetic makeup of an organism | genotype |
passing of traits from parent to offspring | heredity |
alleles are different | heterozygous |
alleles are the same | homozygous |
offspring of crosses between parents with different forms of a trait, example: (Tall x Short) | hybrid |
genetic cross comparing one trait | monohybrid |
the true-breeding stock used by Mendel in his pea plant experiments; would produce offspring identical to themselves when self-pollinated | parental generation (P) |
the physical characteristics of an organism | phenotype |
some alleles are dominant and mask the expression of other alleles; masked alleles are recessive alleles | principle of dominance |
genes (alleles) for different traits segregate independently during the formation of gametes | principle of independent assortment |
genes (alleles) separate (segregate) during the formation of gametes | principle of segregation |
an allele that is masked by a dominant allele | recessive allele |
a characteristic of an organism | trait |
