Two genes determine a trait, e.g. eye colour (i will use eye colour as my example).
You get one gene from your mother, and one gene from your father. Different genes may be dominant or recessive. In eye colour, Blue is a recessive trait and brown ia a dominant trait.
That means that in the case of receiving a blue gene from your mother, and brown gene from your father, you will have brown eyes as it is dominant, as you only require ONE gene to show that trait, (although you may have two). However, you have to have BOTH recessive genes to have the recessive trait, meaning you have to be heterogenous for the gene.
Hope that helped :)
What else can I help you with?
What makes a dominant alleles different from a recessive alleles?
A dominant alle masks the expression of the recessive trait in a heterozygous genotype, a recessive allele is the phenotpye expressed is the recessive trait.
What makes a dominant allele different from recessive Allie?
A dominant alle masks the expression of the recessive trait in a heterozygous genotype, a recessive allele is the phenotpye expressed is the recessive trait.
How is codominance different from a dominant and recessive relationship?
In codominance, both alleles in a gene pair are expressed equally, resulting in a blending of traits. This is different from a dominant and recessive relationship, where one allele is dominant and masks the expression of the recessive allele.
How is dominant trait and recessive trait related?
They are related to each other because whether they are dominant or recessive they are both homozygous, meaning the same. They can either be homozygous dominant or homozygous recessive. If they are heterozygous then they are different because it contains one dominant and one recessive allele each. EX: AA=homozygous dominant allele aa=homozygous recessive allele Aa=heterozygous allele
What makes a dominant allel different from?
A dominant alle masks the expression of the recessive trait in a heterozygous genotype, a recessive allele is the phenotpye expressed is the recessive trait.
If a gene has one completely dominant allele and one recessive allele how many different traits can these alleles produce?
A gene with one completely dominant allele and one recessive allele can produce two different traits in a population. Individuals with two dominant alleles (homozygous dominant) and those with one dominant and one recessive allele (heterozygous) will exhibit the dominant trait, while only individuals with two recessive alleles (homozygous recessive) will display the recessive trait. Therefore, the two traits produced are the dominant trait and the recessive trait.
How Dominant allele different from recessive allele?
You need two recessive alleles to get their trait, but only one dominant allele to get that trait. A dominant allele basically overrides a recessive one if they are together, but the recessive gene can show up in offspring.
How is recessive alleles different from dominant alleles?
You need two recessive alleles to get their trait, but only one dominant allele to get that trait. A dominant allele basically overrides a recessive one if they are together, but the recessive gene can show up in offspring.
Is a recessive allele different from a dominant allele?
Yes, a recessive allele is masked or overridden by a dominant allele in a heterozygous individual. This means that the dominant allele's trait will be expressed. In contrast, a recessive allele's trait will only be expressed if an individual has two copies of the recessive allele.
What can be dominant or recessive?
Alleles can be dominant or recessive
Is it possible to have a dominate recessive trait?
no, because dominant is different from recessive, its impossible to have a dominant-recessive trait because the dominant is when only one copy of the gene is present, while in the recessive a trait that must be contributed by both parents in order to appear in the offspring, in short the dominant is for single parent, while in the recessive is a product of two parents.
What term describes an individual that has a dominant and a recessive allele for a trait?
The term for an individual with a dominant and a recessive allele for a trait is "heterozygous." This means they have two different alleles for a specific gene, with one being dominant and the other recessive.
