Best answer: What is it called when two alleles have 1 capital and 1 lower case letters?

What 2 terms describe an allele combination with one capital and one lower case letter?

Genotypes are usually represented as letters, with a capital letter representing the dominant allele and the lowercase letter representing the recessive allele. A homozygous genotype is one in which both alleles are the same, and an organism with a homozygous genotype is said to be true-breeding or purebred.

When one letter is capital and one is lowercase in genetics?

We use two letters to represent the genotype. A capital letter represents the dominant form of a gene (allele) and a lowercase letter is the abbreviation for the recessive form of the gene (allele).

What is a pair of alleles represented by either capital or lowercase letters?

Alleles that are the same (either both dominant or both recessive) are called homozygous (same) alleles and are represented by two upper case letters for dominant or two lower case letters for recessive.

Is heterozygous capital or lowercase?

If an organism is heterozygous, the capital letter always comes first. For example: Tt NOT tT.

What term is used when two different alleles are combined together?

heterozygous. a genotype consisting of two different alleles of a gene for a particular trait (Aa). Individuals who are heterozygous for a trait are referred to as heterozygotes.

What is it called when a genotype contains a capital and lowercase letter *?

Heterozygous. An organism is heterozygous for a trait (characteristic), when the two alleles in pair are different. A heterozygous genotype would have one capital and one lowercase letter.

What is the term heterozygous mean?

(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).

When the two allele in a pair are the same form of the allele the pair is known as?

If the two alleles are the same, the individual is homozygous for that gene. If the alleles are different, the individual is heterozygous.

When the two alleles in a pair are different forms of the same allele they are?

Each pair of alleles represents the genotype of a specific gene. Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two alleles differ.

What does dominant refer to?

The definition of dominant is a person who is in a position of power or who is exhibiting powerful or controlling tendencies. An example of dominant is a strong and powerful CEO. … Dominant refers to a gene that will present itself by producing a characteristic that can be inherited.
