A polyallelic trait is a trait controlled by multiple alleles (variants of a gene) at a single gene locus. This means there are more than two possible alleles that can influence the trait's expression, resulting in a range of phenotypic variations. This can lead to a complex inheritance pattern.

Is a Rabbit's fur color a multiple allelic trait?
Yes, a rabbit's fur color is a multiallelic triat. However, the color is also influenced by environmental conditions, especially the cold.
What is the function of allelic ladder?
An allelic ladder is a mixture of DNA fragments of known sizes that are used as a reference to estimate the size of DNA fragments in a sample by gel electrophoresis. It helps in determining the sizes of unknown DNA fragments by comparing their migration distances to those of the fragments in the allelic ladder on the gel.
A condition in which a diploid organism has different allelic forms of a particular gene is the definition of?
Heterozygosity is the condition in which a diploid organism possesses different allelic forms of a particular gene.
An inheritance pattern in which a gene has more than two alleles?
Polygenic inheritance is an inheritance pattern in which a trait is controlled by multiple genes, each with two or more alleles. This results in a continuous range of phenotypes rather than distinct categories.
What are organisms with the genotype tt is also know as?
two capital or two lowercase letters in the GENOTYPE (ex: TT or tt) it's also called HOMOZYGOUS.
What is the relationship between a non-allelic gene and the expression of a specific trait in an organism?
Non-allelic genes are genes located on different chromosomes that do not directly influence each other. They can affect the expression of a specific trait in an organism through independent pathways, leading to a combination of different genetic factors influencing the trait.
Is a Rabbit's fur color a multiple allelic trait?
Yes, a rabbit's fur color is a multiallelic triat. However, the color is also influenced by environmental conditions, especially the cold.
What is polygeny?
Inheritance in which more than one gene pair affects the appearance of a particular trait. Polygenetic inheritance refers to the non-Mendelian form of inheritance in which a particular trait is produced by the interaction of many genes.
Allelic and non-allelic interaction?
Allelic interaction refers to the interaction between two alleles of the same gene, while non-allelic interaction involves interactions between genes that are not alleles but are located on different loci in the genome. In allelic interactions, the alleles can be dominant or recessive to each other, while in non-allelic interactions, the genes may be involved in the same pathway or biological process.
How are the word parts poly- and genic related to the meaning of the term polygenic traits?
The word part poly- means "many," and genic refers to genes. Polygenic traits are determined by multiple genes, each contributing a small effect to the overall trait. So, the terms poly- and genic in polygenic traits indicate that multiple genes are involved in determining the trait.
What is an allelic dropout?
An allelic dropout is a failure to determine an allele within a sample. This occurs when one or both allelic copies were not amplified during the polymerase chain reaction.
When will a recessive trait show its effect?
A recessive trait will be expressed when there is no dominant allele in the genotype for that trait. In a Mendelian trait, where one gene with one dominant and one recessive allele governs a trait, a recessive trait will be expressed when the individual's genotype for that trait is homozygous recessive, meaning that both of the individual's alleles for that trait are recessive.
What is the function of allelic ladder?
An allelic ladder is a mixture of DNA fragments of known sizes that are used as a reference to estimate the size of DNA fragments in a sample by gel electrophoresis. It helps in determining the sizes of unknown DNA fragments by comparing their migration distances to those of the fragments in the allelic ladder on the gel.
Are they roly poly or poly roly?
It is called roly poly
