What is the expressed genetic trait?
The genetic contribution to a trait is called the genotype. The outward expression of the genotype is called the phenotype.
What are inherited traits and how can they be expressed?
Inherited traits are coded in our DNA and hence can be disseminated on to the next generation. Example: Eye color, height, Skin color, Colour of hair, etc. For similar traits, there are two duplicates of genes in sexually reproducing individuals.
What are examples of genetic traits?
For example, if both of your parents have green eyes, you might inherit the trait for green eyes from them. Or if your mom has freckles, you might have freckles too because you inherited the trait for freckles. Genes aren’t just found in humans — all animals and plants have genes, too.
Which is an example of a lethal inheritance pattern?
Lethal Inheritance Patterns. Occasionally, a nonfunctional allele for an essential gene can arise by mutation and be transmitted in a population as long as individuals with this allele also have a wild-type, functional copy. The wild-type allele functions at a capacity sufficient to sustain life and is, therefore,…
Which is individuals determine the pattern of inheritance in this pedigree?
Those parents must be dominant, and that child must be recessive. (In this example, shaded is dominant and unshaded is recessive.) Which individuals determine the pattern of inheritance in this pedigree? Nice work! You just studied 140 terms! Now up your study game with Learn mode.
Can a person have both recessive and dominant alleles?
Individuals receive one version of a gene, called an allele, from each parent. If the alleles are different, the dominant allele usually will be expressed, while the effect of the other allele, called recessive, is masked. In codominance, however, neither allele is recessive and the phenotypes of both alleles are expressed.
What is the relationship between two versions of a gene?
Codominance is a relationship between two versions of a gene.
