What is it when you have a gene pair that consist of two dominate alleles and two recessive alleles?
The name of the gene pair that consists of a dominant and recessive allele, i.e. (Xx) will be a heterozygous allele. In this situation, the characteristics of the dominant characteristic will mask that of the recessive allele. People have have a heterozygous genotype may be carriers for diseases that reside on the recessive allele.
What else can I help you with?
Gene pairs consists of two dominant alleles or two recessive alleles?
A gene pair that consists of a dominant allele and a recessive allele is called a heterozygous gene. A homozygous gene, meanwhile, is a gene pair consisting of two dominant alleles or two recessive alleles.
What are two forms that a gene or allele may take?
A gene or allele may take a dominant form, or a recessive form. If the allele is recessive, the characteristic which is coded for will be exhibited only if both the gene from the male and the gene from the female is recessive. Only one copy of a dominant allele is required to cause expression of the dominant characteristic
What is it called when an organism inherited two of the same alleles of a gene from its parents?
Then you will have two copies of the same gene, a condition known as having identical alleles. If the particular gene is recessive (such as for blue eyes) this is the only way it will be able to express itself.
What is TT Tt tt?
These are letters assigned to alleles or variations in genes. TT means that there are two dominate alleles. Tt means that there is one dominate and one recessive and tt means that both are recessive.
What is an example of a different form a gene may have for a trait?
The different forms of a genes for a single trait are known as alleles there can be a dominate allele which always shows up when present and a recessive allele which only shows up when both alleles are recessive or there is no dominate allele
How many alleles are usually in the gene pool for each trait?
Each gene has a dominate and recessive allele, so there are two types of alleles in each gene. The dominate allele is stronger than the recessive allele unless there are two recessive alleles.
What is a gene pair called when is consist of two dominant alleles or two recessive alleles?
Homozygous
Are alleles dominant or recessive?
Alleles are neither entirely recessive nor entirely dominate. An allele is any one of a number of alternative forms of the same gene on a chromosome.For example: say a flower only blooms either red or white flowers. There is a different allele for each color-- a red allele and a white allele. Now, one color may be dominate over the other recessive gene. For example, if the red color was dominate and the white color was recessive, then those certain alleles would be dominate and recessive, respectively. But alleles in general cannot be either recessive or dominate. It depends on the gene and it depends on the trait.
Why are recessive alleles not always expressed as the phenotype?
recessive alleles get masked to show the difference in a dominant gene and a recessive gene. the dominate genes masks the recessive genes to show that the dominate gene is more dominate or more likely to be the outcome than the reccessive gene but the masked gene is not always recessive.
Gene pairs consists of two dominant alleles or two recessive alleles?
A gene pair that consists of a dominant allele and a recessive allele is called a heterozygous gene. A homozygous gene, meanwhile, is a gene pair consisting of two dominant alleles or two recessive alleles.
What are two forms that a gene or allele may take?
A gene or allele may take a dominant form, or a recessive form. If the allele is recessive, the characteristic which is coded for will be exhibited only if both the gene from the male and the gene from the female is recessive. Only one copy of a dominant allele is required to cause expression of the dominant characteristic
Why are traits controlled by recessive alleles on the X chromosome are more common in males than in females?
Males only have one X chromosome, so even if the gene on that chromosome is recessive there is no other gene that could dominate it. Females have two X chromosomes, so if the gene on that chromosome is recessive there is still a chance that the gene on the other chromosome could be dominate and override it.
What type of alleles are presented in a homozygous genotype?
homozygous(different gene)-Rr heterozygous(same gene)-RR,rr
What is gene pair consists of two dominant alleles or two recessive alleles?
A gene pair that consists of 2 dominant or 2 recessive alleles is considered homozygous dominant or homozygous recessive.
Is the gene for a miniature breed of dog dominate or recessive?
recessive
Recessive allele different from dominate 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.
Are alleles recessive?
Alleles can be either dominant or recessive. They can be identical or different for any given gene in a somatic cell, and can represent alternative forms of a gene.
