When a pair of gene go together it is called as?

When a pair of gene go together it is called as?

An allele is a variant form of a gene. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent. Each pair of alleles represents the genotype of a specific gene.

What are the pairs of genes responsible for traits called?

Within an individual organism, the specific combination of alleles for a gene is known as the genotype of the organism, and (as mentioned above) the physical trait associated with that genotype is called the phenotype of the organism.

What term means that a trait is a combination of many genes?

= A polygenic trait is one whose phenotype is influenced by more than one gene. Traits that display a continuous distribution, such as height or skin color, are polygenic.

What are paired chromosomes called?

Homologous chromosomes are made up of chromosome pairs of approximately the same length, centromere position, and staining pattern, for genes with the same corresponding loci. One homologous chromosome is inherited from the organism’s mother; the other is inherited from the organism’s father.

What do you call the cross of two traits?

A dihybrid cross describes a mating experiment between two organisms that are identically hybrid for two traits. In 1865, Gregor Mendel performed dihybrid crosses on pea plants and discovered a fundamental law of genetics called the Law of Independent Assortment.

What term refers to the gene that is expressed when two different genes for a trait are present in a gene pair?

An organism which has two different alleles of the gene is called heterozygous. Phenotypes (the expressed characteristics) associated with a certain allele can sometimes be dominant or recessive, but often they are neither.

When do gene pairs act together to produce a trait?

Occcurs when many gene pairs act together to produce a single trait. Occurs when a group of gene pairs acts together and produces a specific trait, such as human eye color, skin color, or height.

What’s the difference between a gene and a trait?

Updated January 27, 2019. A gene is a portion of DNA that determines a trait. A trait is a characteristic, or a feature, passed from one generation to another, like height or eye color.

What does it mean when two genes are the same?

When the two inherited alleles for a given gene are identical, this specific gene is called homozygous. Alternatively, when the two genes are different, the gene is said to be heterozygous. Dominant traits require the presence of only one allele in order for the given trait be expressed.

What does heterozygous term mean in genetics?

Term that describes two paired alleles (letters) that are exactly the same Heterozygous Term that describes two paired alleles(letters) that are different from each other Trait A physical characteristic that an organism can pass on to its offspring through its genes.
