Frequent question: Which statement best describes what a genotype is quizlet?

The genotype of an organism describes the specific alleles for a particular gene, and the phenotype describes the appearance of the organism associated with the genotype. An organism has the genotype “Aa”, where the capital letters represent dominant allele and lowercase letters represent recessive alleles.

What is the best definition of genotype quizlet?

genotype. an organism’s genetic makeup, or allele combinations.

What is a genotype biology quizlet?

genotype. The entire genetic makeup of an organism; also the combination of genes for one or more specific traits. Phenotype. An organisms appearance or other detectable characteristic that results from the organisms genotype and the environment.

Which best describes a genotype and phenotype respectively?

The two terms are often used at the same time to describe the same organism, but there is a difference between genotype and phenotype: An organism’s genotype is the set of genes in its DNA responsible for a particular trait. An organism’s phenotype is the physical expression of those genes.

Which of the following terms best describes a cell with the genotype AA?

The term “homozygous” is used to describe the pairs “AA” and “aa” because the alleles in the pair are the same, i.e. both dominant or both recessive.

Which statement best describes a genotype?

The genotype of an organism describes the specific alleles for a particular gene, and the phenotype describes the appearance of the organism associated with the genotype. An organism has the genotype “Aa”, where the capital letters represent dominant allele and lowercase letters represent recessive alleles.

What best describes a person’s genotype?

A genotype is an individual’s collection of genes. The term also can refer to the two alleles inherited for a particular gene. The genotype is expressed when the information encoded in the genes’ DNA is used to make protein and RNA molecules.

What is the genotype of an individual quizlet?

A genotype is an individual’s collection of genes. The term also can refer to the two alleles inherited for a particular gene. The genotype is expressed when the information encoded in the genes’ DNA is used to make protein and RNA molecules.

Which describes a genotype homozygous dominant for a single trait?

An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype.

What is a heterozygous in biology quizlet?

heterozygous. an organism that has two different alleles for a trait (hybrid)

What’s an example of a genotype?

Genotype examples

IT IS SURPRISING:  What is total phenotypic variance?

A gene encodes eye color. In this example, the allele is either brown, or blue, with one inherited from the mother, and the other inherited from the father. The brown allele is dominant (B), and the blue allele is recessive (b).

How do you determine a genotype?

A Punnett square is one of the simplest ways to determine genotype. The square is actually a mini-chart used to determine the potential genotype for an offspring with respect to particular trait.

What are 3 examples of genotype?

Examples of Genotype:

  • Height. For an individual’s gene makeup there is tall variety (T) and there is short variety (s). T and s are called the alleles. …
  • Freckles or no freckles. Again the information that is passed from parent to child is carried in the cell of the genotype. …
  • Lactose intolerance.

What is the meaning of AA AS and SS genotype?

Blood genotype indicates of the type of protein (Haemoglobin) that is in the red blood cells. You could be Haemoglobin AA, AS, AC, SS or SC based on what is inherited from your parents. Individuals with blood genotype SC and SS are said to have sickle cell disease while AS is known as sickle cell trait.

What’s the relationship between genotype and phenotype?

The genotype of an organism is defined as the sum of all its genes. The phenotype of an organism is the observable physical or biochemical characteristics of an organism, determined by both genetic make-up and environmental influences.

What is AA in genetics?

The genetic symbols can be understood as. A = dominant. a = recessive. AA- homozygous dominant.
