An all allele is a variant form of a gene that arises by mutation and is found at the same locus on a chromosome. Alleles can differ in their nucleotide sequence, which may result in different traits or characteristics expressed in an organism. For example, in the gene that determines flower color, one allele might produce red flowers while another produces white flowers. The combination of alleles inherited from parents determines the organism's genotype and phenotype.
What else can I help you with?
If an allele for a particular trait is NOT expressed at all when another allele for the trait is present the allele is .?
The allele not expressed would be recessive whilst the other is dominant. This would be the case in a heterozygous genotype. Hope this helps

What is meant by alleles?
Allele frequency, or gene frequency, is the proportion of a particular allele (variant of a gene) among all allele copies being considered. It can be formally defined as the percentage of all alleles at a given locus in a population gene pool represented by a particular allele.
If all of the sex cells of an organism have the t allele the genotype of that organism must be?
The genotype of the organism must be tt, because sex cells (gametes) only carry one allele each. When gametes carrying the same allele combine during fertilization, the resulting genotype is homozygous for that allele. In this case, if all sex cells have the t allele, the organism's genotype is tt.
When does a dominant allele control a charteristic?
at all times
What is an fixed allele APEX?
an allele present in all members of a population- APEX
What type of allele is in the all of the egg nuclei?
the dominant allele is in all egg nuclei.
What is meant by allele frequence?
How often a certain allele (or trait) occurs in a certain population.
What is the most likely cause of directional selection?
Homoygotes for one allele are favored over all others.
What is a fixed allele.?
An allele present in all members of a population

What is allele masked by the dominant allele?
An allele that is masked by the dominant allele is called a recessive allele. When an individual has one dominant allele and one recessive allele, only the trait determined by the dominant allele will be expressed. The recessive allele will only be expressed if an individual has two copies of it (homozygous recessive).
If all of the sex cells of an organism have the t allele the genotype of that organism must be?
The genotype of the organism must be tt, because sex cells (gametes) only carry one allele each. When gametes carrying the same allele combine during fertilization, the resulting genotype is homozygous for that allele. In this case, if all sex cells have the t allele, the organism's genotype is tt.
