What does it mean to be phenotypically normal?
a. The observable physical or biochemical characteristics of an organism, as determined by both genetic makeup and environmental influences. b. The expression of a specific trait, such as stature or blood type, based on genetic and environmental influences.
What are 3 examples of phenotypes?
- 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 a phenotype in medical terms?
Listen to pronunciation. (FEE-noh-tipe) The observable characteristics in an individual resulting from the expression of genes; the clinical presentation of an individual with a particular genotype.
What is phenotypically female?
Most people have either two X chromosomes (genotypic female) or an X and a Y chromosome (genotypic male). Phenotypic sex refers to an individual’s sex as determined by their internal and external genitalia, expression of secondary sex characteristics, and behavior.
Why must males inherit colorblindness from their mothers?
Since it’s passed down on the X chromosome, red-green color blindness is more common in men. This is because: Males have only 1 X chromosome, from their mother. If that X chromosome has the gene for red-green color blindness (instead of a normal X chromosome), they will have red-green color blindness.
What is phenotype and example?
The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. … Examples of phenotypes include height, wing length, and hair color.
What is phenotype in your own words?
Phenotype refers to the observable characteristics of an organism as a multifactorial consequence of genetic traits and environmental influences. The organism phenotype includes its morphological, biochemical, physiological, and behavioral properties.
Are blue eyes a phenotype?
Finally, the genotype of an organism with two recessive alleles is called homozygous recessive. In the eye color example, this genotype is written bb. Of these three genotypes, only bb, the homozygous recessive genotype, will produce a phenotype of blue eyes.
Can ones genotype change?
Genotype generally remains constant from one environment to another, although occasional spontaneous mutations may occur which cause it to change. However, when the same genotype is subjected to different environments, it can produce a wide range of phenotypes.
How do you express phenotype?
Phenotype is determined by an individual’s genotype and expressed genes, random genetic variation, and environmental influences. Examples of an organism’s phenotype include traits such as color, height, size, shape, and behavior.
What is the difference between phenotype and phenotyping?
Genotype versus phenotype. An organism’s genotype is the set of genes that it carries. An organism’s phenotype is all of its observable characteristics — which are influenced both by its genotype and by the environment. … For example, differences in the genotypes can produce different phenotypes.
Is DNA a phenotype?
DNA phenotyping is the science of predicting an organism’s observable physical or biochemical characteristics (phenotype) by using only genetic information from DNA sequencing or genotyping. … The technique is primarily used to predict a person’s physical appearance and/or ancestry for forensic purposes.
