When both dominant and recessive alleles are present within a single nucleus the organism is for the trait?

You are supposed to have 2 alleles in a single nucleus and if not there can be a disorder i believe.


What are different forms of a single gene called?

alleles


What are both inherited alleles called?

Genetic makeup formed from both inherited alleles together is called a genotype. Homozygous alleles would be a pair of identical alleles for a single trait. Heterozygous is different alleles for a single trait.


What do geneticists call alleles that are both expressed in the phenotype when they are together?

Genetic makeup formed from both inherited alleles together is called a genotype. Homozygous alleles would be a pair of identical alleles for a single trait. Heterozygous is different alleles for a single trait.


What three or more forms of a gene that code for a single trait called?

A gene can have multiple forms, which are called Alleles. While a single gene may code for a trait in an organism, when multiple alleles exist for that gene, each different may produce a different character of that trait. For example, a person has two copies of the gene that codes for ABO blood type. There are three different alleles for this gene, A, B and O. This results in six different combinations of the alleles that the person can have (the genotype), which in turn results in four expressions of the gene in the person (called the phenotype), which is the blood type of the person.


An organism with two different alleles for a single trait is said to be heterozygous?

A heterozygous is a hybrid of genes. It has a dominant and recessive gene. The dominant gene covers over the recessive trait, making the individual have the dominant trait. (trait are alleles...) or apex ans:two


What are alleless?

having the some alleles in a single trait.


How does the range of phenotypes for single gene traits different from the range for polygenic traits?

ABO Single gene trait blood group alleles on humans. That is the variation, not much, and not much recombination. 3! = 6. There is posited to be at least 7 alleles for height, which is a polygenic trait. Hypothetical alleles, SMYDKECV 7! = 5040 different combinations of alleles in height polygenic traits.

multiple alleles


What is multiple aleles?

Multiple alleles indicates that either the study is being conducted on alleles at more than one gene locus, that the characteristic being studied is controlled by several alleles at different loci or that there are two or more alleles at a single gene locus.
