Alleles are different types of a gene. Each gene controls a characteristic and they is usually a recessive allele and a dominant one. The main similarity is that they both control a certain characteristic!

∙ 9y agoA dominant allele produces the phenotype when paired with a recessive allele. Recessive alleles must be paired together to produce the phenotype (trait).

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 is the opposite of homozygous of dominant?
heterozygous recessive
What gene is masked if it is paired with a dominant gene?
The different forms of a gene are called alleles. In Mendelian genetics, a gene has a dominant allele and a recessive allele. The dominant allele masks the recessive allele if present. So there are two possible dominant genotypes: homozygous dominant, in which both dominant alleles are present; and heterozygous, in which one allele is dominant and the other allele is recessive. The only way to express a recessive trait is to have the homozygous recessive genotype.
A single gene trait that has two alleles and that shows a simple dominant recessive pattern will result in?
A 3:1 phenotypic ratio (Mendelian inheritance).
Are dominant alleles naturally better for an organism?
No, recessive alleles are equally likely to be inherited (if your dealing with only those two types of alleles). BUT, dominant alleles are the ones that show up. That is precisely why they are called dominant. Compared to recessive alleles, dominant ones will overrule the others, making it the one inherited.
What can be dominant or recessive?
Alleles can be dominant or recessive
How are dominant and recessive alleles are 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.
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.
What type of alleles mask recessive alleles?
Dominant alleles :-)
How dominant and recessive alleles are represented in a Punnett Square?
Dominant alleles are written in upper case (i.e, 'A'), while recessive alleles are lower case (i.e, 'a')
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.
How dominant and recessive are represented in a punnet square?
Dominant alleles are shown by a capital letter and recessive alleles are lowercase letters.
How do dominant alleles recessive alleles differs?
Dominant alleles are the ones that show up in the phenotype. Recessive alleles do not unless both alleles are recessive, but can be passed on. For example: Tt , T=tall and t=short. Tall is dominant and short is recessive. You are tall and can pass on the short gene. Or, you can use black hair being dominant over red. Or, brown eyes being dominant over blue. Dominant can be seen on you and recessive can't.
Why are recessive alleles not removed from populations over time?
If the recessive genotype is selected for more often than the dominant genotype, the recessive allele will become more common than the dominant allele in the gene pool.
What is recessive and dominant mean?
I am pretty sure the recessive and dominant alleles you are talking about are covered in Biology. Recessive alleles are basically alleles that are received from both parent's DNA that are carries, (dd). However, dominant alleles are (exactly what it says) always expressed. If there is one dominant allele and one recessive allele the dominant allele overpowers the recessive. (DD) and (Dd)overpowers (dd).
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.
