A | B |
Law of Dominance | some alleles are dominant and others are recessive. |
Law of Segregation | alleles separate during gamete formation. |
Gene | The chemical factors that determine traits; made up of two alleles. |
Pollen (sperm) | male reproductie cells |
Egg | female reproductive cells |
Anther, carpel | top part of stigma |
Fertilization | process in sexual reproduction in which male and female reproductive cells join to form a new cell. |
Self pollination | sperm cells in pollen fertizlize egg cells in the same flower |
True Breeding | organisms that produce offspring identical to themselves if allwed to self-polinate |
Heterozygous | term used to refer to an organism that has two different alleles for the same trait. |
Hybrid | offspring of crosses between parents with different traits. |
F1 | offspring of each original pair of plants, the P(parental) generaltion. |
Punnett Square | diagram showing the gene combinations that a partcular eventwill occur. |
Probability | likelihood that a particular event will occur. |
Allele | the different forms of a gene |
Homozygous | organisms that have two identical alleles for a particular trail (e.g., TT or tt) |
Phenotype | physical characteristics of an organism |
Genotype | the genetic makeup of an organism |
Incomplete Dominance | situation in which one allele is not completely dominant over another. |
Codominance | situation in which both alleles of a gene contribute to the phenotype of the organism |
Multiple Alleles | situation in which genes have more than two alleles. |
