In a broad sense, the term “genotype” refers to the genetic makeup of an organism; in other words, it describes an organism’s complete set of genes. In a more narrow sense, the term can be used to refer to the alleles, or variant forms of a gene, that are carried by an organism.
What is genotype and example?
A genotype is a scoring of the type of variant present at a given location (i.e., a locus) in the genome. It can be represented by symbols. For example, BB, Bb, bb could be used to represent a given variant in a gene.
What is meant by genotype and phenotype psychology?
An individual’s genotype is the combination of alleles that they possess for a specific gene. An individual’s phenotype is the combination of their observable characteristics or traits.
What is the definition of phenotype in psychology?
Phenotype refers to an individual’s observable traits, such as height, eye color and blood type. A person’s phenotype is determined by both their genomic makeup (genotype) and environmental factors.

What are the 3 types of genotypes?
The different types of genotypes are- homozygous recessive (pp), homozygous dominant (PP), and heterozygous (Pp). The homozygous dominant and the heterozygous genotypes show the same phenotypes.
What is difference between genotype and 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.
What is the best definition of a phenotype?
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 a phenotype quizlet psychology?
Phenotype. the observable characteristics produced by one’s genetic endowment.
What is an example for 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 are 3 examples of phenotype?
In humans, phenotype examples include earwax type, height, blood type, eye color, freckles, and hair color. And phenotypes aren’t just physical traits. Behavior is also considered a phenotype.
What are the 4 types of genotypes?
There are four hemoglobin genotypes (hemoglobin pairs/formations) in humans: AA, AS, SS and AC (uncommon). SS and AC are the abnormal genotypes or the sickle cells. We all have a specific pair of these hemoglobin in our blood which we inherited from both parents.
What are the 5 types of genotype?
A blood genotype indicates the genetic makeup of an individual’s blood in its entirety. Typically, there are five (5) distinct types of blood genotype. They are AA, AS, AC, SS, and SC.
Is eye color a genotype or phenotype?
Eye color, hair color, and blood type are all phenotypes.
Can 2 brown eyes make blue?
Yes. The short answer is that brown-eyed parents can have kids with brown, blue or virtually any other color eyes.
What eye color is the rarest?
At some point, you’ve probably wondered what the rarest eye color is. The answer is green, according to the American Academy of Ophthalmology (AAO). Only about 2 percent of the world’s population sport this shade.
Is dark skin dominant or recessive?
Each gene has two forms: dark skin allele (A, B, and C) and light skin allele (a, b, and c). Neither allele is completely dominant to the other, and heterozygotes exhibit an intermediate phenotype (incomplete dominance). Each dark skin allele in the genotype adds pigment by increasing melanin production.
What was the color of the first humans?
From about 1.2 million years ago to less than 100,000 years ago, archaic humans, including archaic Homo sapiens, were dark-skinned.
What genes are inherited from father only?
All men inherit a Y chromosome from their father, which means all traits that are only found on the Y chromosome come from dad, not mom. The Supporting Evidence: Y-linked traits follow a clear paternal lineage.
Which parent determines the skin color of baby?
When a baby inherits skin color genes from both biological parents, a mixture of different genes will determine their skin color. Since a baby inherits half its genes from each biological parent, its physical appearance will be a mix of both.
