What is the expression of a trait dependent on?
Expression of X-linked traits depends on a number of factors including a dominant versus recessive allele, and the gender of the offspring. While Punnett squares provide information about offspring, pedigrees are diagrams that allow individuals to visualize patterns of inheritance throughout their family history.
How do genes determine traits?
Like chromosomes, genes also come in pairs. Each of your parents has two copies of each of their genes, and each parent passes along just one copy to make up the genes you have. Genes that are passed on to you determine many of your traits, such as your hair color and skin color.
What influences the expression of traits?
The expression of genes in an organism can be influenced by the environment, including the external world in which the organism is located or develops, as well as the organism’s internal world, which includes such factors as its hormones and metabolism.
How is the expression of a trait determined?
Traits can be controlled by incomplete alleles and codominant alleles, or by genes with more than two possible alleles. Secondly, what determines the expression of traits? Traits can be determined by genes or the environment, or more commonly by interactions between them. The genetic contribution to a trait is called the genotype.
How is the genetic contribution to a trait determined?
Traits can be determined by genes or the environment, or more commonly by interactions between them. The genetic contribution to a trait is called the genotype. The outward expression of the genotype is called the phenotype.
How are the traits of an organism determined?
A trait is a specific characteristic of an organism. Traits can be determined by genes or the environment, or more commonly by interactions between them. The genetic contribution to a trait is called the genotype. The outward expression of the genotype is called the phenotype.
Which is an example of a specific trait?
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.
