a dominant allele is basically the one stronger, more powerful. unlike the recessive allele,

i.e if two people wanted to calculate the probability of them having a baby with brown eyes, theyd have to look at their alleles, if the father had brown eyes, XX (to show how brown eyes are stronger) and the mother had hazel eyes (xx) their chid is going to have (Xx) which in this case, the child will have brown eys, because X is more dominant(strong) than x (recessive)

What does the ressesive allele mean?

O alelo recessivo é uma forma alternativa de um gene que não se manifesta quando um alelo dominante está presente. Em termos genéticos, os organismos têm duas cópias de cada gene, uma herdada de cada progenitor. Essas cópias podem ser diferentes (heterozigotas) ou iguais (homozigotas). Um alelo recessivo só se expressa fenotipicamente (ou seja, aparece no organismo) se um indivíduo possui dois alelos recessivos para um determinado gene. Por exemplo, se considerarmos a cor dos olhos, se o alelo para olhos castanhos (dominante) for presente junto com um alelo para olhos azuis (recessivo), a cor dos olhos da pessoa será castanha, já que o alelo dominante prevalece. Resumidamente, o alelo recessivo se manifesta de forma visível apenas na presença de dois alelos recessivos, enquanto um alelo dominante pode mascarar a sua expressão. Essa dinâmica está na base de muitos padrões hereditários e é fundamental para a compreensão da genética.


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).


Allele that prevents the expression of a recessive allele?

A dominant allele


What does the word dominant mean in genetics?

In genetics, "dominant" refers to an allele that will be expressed in the phenotype if present, masking the expression of the corresponding recessive allele. This means that even if an individual has one dominant allele and one recessive allele for a particular trait, the dominant allele's phenotype will be visible.


What does it mean when an allele reaches fixation in a population?

When an allele reaches fixation in a population, it means that all individuals in the population carry that specific allele, and no other alleles for that gene are present. This can happen through natural selection, genetic drift, or other evolutionary processes.

What is an allie that is covered up or hidden?

If you mean allele, then the answer is a recessive allele. A recessive allele is dominated by a dominant allele, and generally does not show up physically.


What is a type of gene?

Do you mean allele? An allele is a different molecular form of the same gene.

What does 'R' and 'r' mean in chromosomes?

R is a dominant allele for trait 'r' and r is a recessive allele for trait 'r'.


What does the term allele mean as is used in genetic crosses?

The term allele is different from a genotype because an allele can be singular, but the alleles that an individual (diploid organism) has at a certain locus are called a genotype.

How do you write dominant and recessive allels?

normally, the dominant allele is expressed as a capital letter and the recessive allele is expressed as a lowercase letter, if that's what you mean!


What does resscessive mean?

What does total dominance of one allele mean?

Total dominance of one allele means that the phenotype associated with that allele is expressed in the heterozygous condition, masking the phenotype of the other allele. This is also known as complete dominance.
