Which trait will be expressed if both dominant gene and recessive gene are in the gene pair?
The current school of thought is that a dominant gene needs only a single copy to express its coding where as a recessive gene needs two copies of itself. The different forms of a gene are called alleles. Each parent contributes an allele. For example brown eyes and blue eyes. A blue eyed person would have two blue eye genes. A brown eyed person would have at least one brown eyed gene and either a blue or brown eyed companion. Hence two blue eyed people should only have blue eyed children. Two brown eyed people could possibly have either blue or brown eyed children. Science is discovering that genes interact in very complex ways. There is dominance, recessive, codominance, corecessive, and interactions between multiple genes to produce an outcome. While the reporting of DNA research and discoveries may make it seem we have an understanding of how genes work the reality is that the study of DNA and its functions is still in its infancy.
How do you use recessive allele in a sentence?
The building blocks of our genes (that make us what we are) are called alleles and these can be either dominant, recessive or codominant - which means they are equally dominant. Now for your sentence: "A typical example of codominance can be found in blood types, where the existence of A as well as B alleles in a person will lead to blood type AB".
What does brown and blonde make?
When brown hair is mixed with blonde highlights, it creates a dimensional and natural-looking hair color that blends the richness of brown with the warmth and brightness of blonde. The result is often referred to as a "bronde" hair color.
What are the two different alleles for a gene?
I think it is Dominant and recessive.
Why is an organism genotype may be homozygous dominant homozygous recessive or heterozygous but never heterozygous recessive?
I take it you're referring to the phenotype. Say a trait, like flower colour, is influenced by a single gene. The plant will possess two copies of the gene, one from each parent, but only one colour is expressed. Let's say that red is dominant and white is recessive. A plant containing 2 red alleles (homozygous for the dominant allele) will be red. A plant containing 2 copies of the white allele (Homozygous recessive) will be white and heterozygous plant, containing a single copy of both alleles will be red. There is no heterozygous recessive because the dominant allele will determine the phenotype.
How are dominant and recessive genes related?
Dominate them. Recessive alleles do not show in your phenotype unless you have two of the same recessive allele. But if you inherit one dominant and one recessive, it is the dominant that always shows in your phenotype.
How are dominant trait and recessive trait the same?
They are both used to format your genetic make up.
What does it mean to be a dominant gene?
Genes which take precedence over their opposite number - recessive genes. i.e. when the genetic make-up of an organism is being determined the dominant gene will out-rank any recessive gene and more often than not be the determinant one.
What does pure dominant mean?
"Pure dominant" refers to a genetic trait that is consistently expressed when a specific allele is present in an individual's genotype. In inheritance patterns, a pure dominant trait will mask the presence of any recessive alleles in the same gene.
How are dominant and recessive genes?
If you are talking about traits, dominant traits and recessive traits both have alleles. Dominant traits are alleles that cover up the expression of other alleles. One dominant allele with one recessive allele makes a dominant trait. Two dominant alleles together also make a dominant trate. Recessive traits are alleles that are only expressed when there is no dominant trait to cover them up. Two recessive alleles make a recessive trait. Traits can be passed over to the next generation. Two alleles together make a genotype, which is the inherited combination of alleles. Alleles: different versions of the same gene. Heredity: determined by genes. Genes: piece of DNA that shows the cell how to make a protein it needs.
How are recessive and genes related?
If you are talking about traits, dominant traits and recessive traits both have alleles. Dominant traits are alleles that cover up the expression of other alleles. One dominant allele with one recessive allele makes a dominant trait. Two dominant alleles together also make a dominant trate. Recessive traits are alleles that are only expressed when there is no dominant trait to cover them up. Two recessive alleles make a recessive trait. Traits can be passed over to the next generation.

How can you make different color in pigeons?
by hybridization with pigeons having different colors new varieties of pigeons are obtained having different colors.In this dominant gene and the recessive gene play an effective role Dominant gene: that suppress the expression of its allele Recessive gene:that is not express in presence of its dominant gene
When can a recessive gene assert itself?
When a parent for example has one dominant and onee recessive e.g Fe and another parent is a carrier for it e.g ee this will make the gene produce a trait of the offspring having a 50% chance of being a carrier
What was Gregor Mendel's biggist contribution to biology?
Gregor Mendel discovered the dominant and recessive mode of genetic inheritance.
Describe what genes are and explain what makes a disease genetic?
genes are what make up your DNA. each gene has two alleles, and whether those alleles are dominant or recessive determines what trait you get. Every trait has at least on gene coding for it, and some have more. a disease is genetic when there is a gene coding for it, as opposed to just a mutation or something environmental causing it.
What factor controls a trait?
A person's genes are what control what traits. Genes can either be recessive or dominant and the combination of many different genes are what make up different traits.
