The way an organism looks based on their genotype is called what? | Phenotype |
The passing of traits from the parents to offspring is known as? | Heredity |
A physical characteristic that and organism has? | Trait |
The study of heredity is known as? | Genetics |
The mathematical chance that something will happen? | Probability |
This trait will always show up in an organism when the allele is present. | Dominant |
The combination of genes (letter combination) is called what? | Genetype |
The part of the DNA that determines our traits? | gene |
If an organism has one dominant allele and one recessive allele (Dd), then they are said to be? | Heterozygous |
If an organism has two dominant traits (TT) or two recessive traits (tt),then they are considered? | Homozygous |
One single gene is called (T)? | Allele |
This trait will only show if there is no dominant trait present | Recessive Trait |

What base connects to Guanine | Cytosine |
Let's say that Round seed shape is dominant R and wrinkled is recessive r. If a plant has wrinkled seeds, what could the possible genotypes be? | rr |
The round seed shape is dominant R and the wrinkled is recessive r. If the plant has round seeds, what could be the possible genotypes? | RR, Rr |
If both parents have RR, then what percentage of the offspring will have wrinkled seeds? | 0% |
Parent 1: Genotype: RR, Phenotype: ? | round |
Parent 2: Genotype rr, Phenotype: ? | wrinkled |
Parent 2: Genotype Rr, Phenotype: ? | round |
