A phenotype is an individual’s observable traits, such as height, eye color, and blood type. The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype, while other traits are largely determined by environmental factors.
What are 3 examples of phenotype?
- Eye color.
- Hair color.
- Sound of your voice.
- Certain types of disease.
- Size of a bird’s beak.
- Length of a fox’s tail.
- Color of the stripes on a cat.
What is an example of a phenotype?
Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
What best defines a phenotype?
The phenotype is best defined as the “observable characteristics that result from the expression of genes of an organism, which can largely be modulated by environmental or other conditions” .
How does DNA determine phenotype?
An organism’s phenotype (physical traits and behaviors) are established by their inherited genes. Genes are certain segments of DNA that code for the production of proteins and determine distinct traits. … If an organism inherits two of the same alleles for a particular trait, it is homozygous for that trait.
What is heterozygous example?
If the two versions are different, you have a heterozygous genotype for that gene. For example, being heterozygous for hair color could mean you have one allele for red hair and one allele for brown hair. The relationship between the two alleles affects which traits are expressed.
What is phenotypic expression?
Phenotypic expression is the result of a complex interplay between an organism’s genes and its environment. During growth and development, organisms undergo a programmed series of phenotypic changes. … The ability to vary phenotypic expression in response to environmental conditions is known as “phenotypic plasticity.”
What are the 3 types of genotypes?
There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous.
What is allele example?
Alleles are different forms of the same gene. … An example of alleles for flower color in pea plants are the dominant purple allele, and the recessive white allele; for height they are the dominant tall allele and recessive short allele; for pea color, they are the dominant yellow allele and recessive green allele.
