What does genotype refer to quizlet?

Genotype refers to the alleles you possess for a particular gene or set of genes. Phenotype is the physical trait itself, which may be influenced by genotype and environmental factors.

What does genotype refer to?

A genotype is an individual’s collection of genes. The term also can refer to the two alleles inherited for a particular gene. … The expression of the genotype contributes to the individual’s observable traits, called the phenotype.

What is a genotype quizlet?

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

What is an example of a genotype quizlet?

Example: An example of a genotype would be HH is the homozygous dominant trait for brown eyes and hh would be the homozygous recessive trait for blue eyes. Example: Both Parents have blue eyes. The offspring has blue eyes. Example: Two parents one with brown hair and one with red hair.

Which of the following is the best definition of genotype 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.

What is the chromosome?

(KROH-muh-some) A structure found inside the nucleus of a cell. A chromosome is made up of proteins and DNA organized into genes. Each cell normally contains 23 pairs of chromosomes.

What does genotype refer to the chromosomes of an organism the genetic make up of an organism the type of gene in question the physical expression of genes?

In one sense, the term “genotype”—like the term “genome”—refers to the entire set of genes in the cells of an organism. In a narrower sense, however, it can refer to different alleles, or variant forms of a gene, for particular traits, or characteristics.

What is genotype example?

Genotype examples

A gene encodes eye color. … If the child inherits two different alleles (heterozygous) then they will have brown eyes. For the child to have blue eyes, they must be homozygous for the blue eye allele.

What does the term phenotype refer to quizlet?

Phenotype. An organism’s appearance or other detectable characteristic. Gene.

What is the genotype of the heterozygote?

Listen to pronunciation. (HEH-teh-roh-ZY-gus JEE-noh-tipe) The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).

What are the differences between genotypes and phenotypes?

The genotype is a set of genes in the DNA which are responsible for the unique trait or characteristics. Whereas the phenotype is the physical appearance or characteristic of the organism. Thus, we can find the human genetic code with the help of their genotype.

What is an allele quizlet?

An allele is an alternative form of a gene (one member of a pair) that is located at a specific position on a specific chromosome. These DNA codings determine distinct traits that can be passed on from parents to offspring.

Is PP genotype or phenotype?

There are three available genotypes, PP (homozygous dominant ), Pp (heterozygous), and pp (homozygous recessive). All three have different genotypes but the first two have the same phenotype (purple) as distinct from the third (white).

What does genotype affect?

The genome in which a genotype is found can affect the expression of that genotype, and the environment can affect the phenotype. Genes can also be pleitropic when they affect more than one trait. The single base pair mutation that lead to sickle cell anemia is a classic example.

Which statement accurately describes how genotypes determine phenotypes?

Which statement accurately describes how genotypes determine phenotypes? genes encode a sequence of amino acids for a particular polypeptide or protein.

Are your genotype and phenotype the same thing quizlet?

The phenotype is an organism’s physical appearance, and the genotype is the genetic makeup.
