Is a situation in which a dominant allele completely masks a recessive allele for a gene?

If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.

What makes dominant alleles different from recessive alleles?

A dominant allele determines the trait.


How can alleles be?

Alleles can either be recessive or dominant. Dominant alleles produce a dominant trait which is normally seen, whereas although the recessive allele is present, the recessive trait is not normally visible. However, in cases of codominance and complete dominance the dominant trait does not completely hide the recessive trait and it can show through.


What kind of alleles does a heterozygous individual have?

a heterozygous individual has different alleles because one is dominant but the other is recessive.


What are two different alleles for a trait?

Humans have two sets of their chromosomes, one from each parent. Two different alleles for a trait are two different versions of a gene, one usually coming from each parent. Alleles are referred to a dominant or recessive. A trait can be homozygous dominant (both the same dominant allele), heterozygous (one dominant and one recessive), or homozygous recessive (both recessive). "Dominant" alleles are named so because when they are paired with a recessive allele, the dominant one is expresses in the organism's phenotype.


Is codominance where neither of the alleles are recessive or dominant?

Yes, codominance is when both alleles of a gene are expressed equally, so that means neither allele is dominant nor recessive.


How are dominant and recessive alleles alike and different?

A dominant allele produces the phenotype when paired with a recessive allele. Recessive alleles must be paired together to produce the phenotype (trait).


How is dominant alleles 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 are recessive alleles different from dominant allele?

Recessive alleles are defective in some way, so they cannot express there trait normally. Dominant alleles are normal and so they expresses better.


What can be dominant or recessive?

Alleles can be dominant or recessive


When alleles are neither dominant or recessive?

this is called codominance when alleles are neither dominant or recessive.


Does a dominant allele mask the effect of a recessive allele?

Dominant alleles override recessive alleles, but do not eliminate them. The recessive alleles can reoccur in future generations despite both parents having dominant alleles.


Are Recessive alleles masked by dominant alleles when both are present in the genotype?

Yes, recessive alleles are hidden due to the dominant alleles.


How is homozygous dominant different from homozygous recessiv?

Homozygous Dominant, or AA is two alleles for a trait that are both dominant Homozygous Recessive, or aa is two alleles for a trait that are both recessive


What are the letters for homozygous dominant heterozygous and homozygous recessive?

homozygous dominant means two alleles that are the same that are capital letters, heterozygous recessive means that to alleles are different BUT the same letters in lower case. (alleles for gender) EX: TT, Tt is homozygous dominant tt, tt is heterozgous recessive


What is a 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.


How is dominant trait and recessive trait related?

A dominant and recessive trait are different expressions of the same gene. The different forms of the gene are called alleles.


Do recessive alleles hide dominant alleles?

No. Dominant alleles always hide recessive. Think of it this way, dominant as in, the leader. That helps me remember that they take over. :) good luck !


How are dominant and recessive alleles represented in a Punnet square?

Dominant alleles are shown by a capital letter and recessive alleles are lowercase letters.


How are Dominant and recessive alleles are represented in Punnet Square?

Dominant alleles are shown by a capital letter and recessive alleles are lowercase letters.


How are dominant and recessive alleles are represented in a punnett square?

the dominant alleles are represented by uppercase letters and the recessive in lowercase letters.


How are dominant and recessive 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. 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.


What is an organism that has two recessive alleles or two dominate alleles called?

Having two recessive alleles is called homozygous recessive. Having two dominant alleles is called homozygous dominant.


What is a gene pair that consists of two dominant alleles or two recessive alleles?

A gene pair that consists of two dominant alleles is called homozygous dominant, and a gene pair that consists of two recessive alleles is called homozygous recessive.
