What controls a trait?
An organism’s traits are controlled by the alleles it inherits from it’s parents. Some alleles are dominant, while other alleles are recessive.
What factors control the appearance of traits?
Trait is a specific characteristic of an individual. For example, their hair color or their blood type. Traits are determined by genes, and also they are determined by the interaction with the environment with genes. And remember that genes are the messages in our DNA that define individual characteristics.
How many factors control a trait?
To summarize, two things determine the traits an organism has: its genotype and the dominance or recessiveness of the alleles it has.
What are most traits controlled by?
Most genetic characteristics or traits are controlled by many genes.
What are two factors that control traits?
ch 5 multigame
| A | B |

| Factors that control traits are called | genes. |
| Scientists call an organism that has two different alleles for a trait a | hybrid. |
| What does the notation AA mean to geneticists? | two dominant alleles |
| What does the notation Aa mean to geneticists? | one dominant allele and one recessive allele |
What are 2 factors that can affect traits?
Various factors, including genetic makeup, exposure to harmful substances, other environmental influences, and age, can affect expressivity. Both penetrance and expressivity can vary: People with the gene may or may not have the trait and, in people with the trait, how the trait is expressed can vary.
Do factors that control a trait exist in pairs?
Understanding Inheritance Mendel concluded that two factors—one from each parent—control each trait. Mendel’s “factors” are part of chromosomes which exist as pairs—one chromosome from each parent. Each cell in an offspring organism contains chromosomes from both parents.
What are the three types of genetic traits?
Types of inheritance
- Dominant.
- Recessive.
- Co-dominant.
- Intermediate.
What controls inherited traits?
Inherited traits are controlled by genes and the complete set of genes within an organism’s genome is called its genotype. The complete set of observable traits of the structure and behavior of an organism is called its phenotype. These traits arise from the interaction of its genotype with the environment.
