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.

What makes dominant alleles different from recessive alleles?
It's in the word! Dominant means bigger or stronger or greater. So the dominant allele is the stronger gene that is going to show whereas the recessive allele is still in you, but is overshadowed by the dominant allele.
How are dominant and recessive genes related?
Dominate them. Recessive alleles do not show in your phenotype unless you have two of the same recessive allele. But if you inherit one dominant and one recessive, it is the dominant that always shows in your phenotype.
What is the difference between a dominant trait and a recessive trait?
A dominate trait will most likely take over the recessive.
Why are most mutations recessive?
Mutations are changes in the DNA. A mutation can change a gene slightly, giving a different allele. The new allele can code for a slightly different protein. If the normal allele codes for an active enzyme, the new allele may still code for the same active enzyme, may code for an inactive protein, or may code for an active enzyme that catalyzes a different reaction. Of these options, coding for the same active enzyme may be the most common, but then we don't usually notice there's been a mutation. Coding for an inactive protein is the next most likely outcome. So, most of the time when there is a mutation that produces any noticeable effect at all, it produces an allele that codes for an inactive protein. A heterozygote Aa produces some active enzyme and some inactive protein. Most often, one "dose" of active enzyme catalyzes the normal reaction enough to produce a normal appearance, so we say that the allele A is dominant, and the mutant allele a is recessive. There are plenty of exceptions. Certain types of dwarfism in humans are caused by a dominant mutant allele, for instance. Still, it's probably true that the majority of mutant alleles are recessive.
What type of alleles are expressed only if two identical copies exist on the homologs of the offspring?
Recessive alleles are expressed only when two identical copies exist on the homologs of the offspring. In this case, if an individual inherits two copies of the recessive allele, it will show the recessive trait.
What makes a dominant allele different from recessive Allie?
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.
What makes a dominant allel different from?
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.
What makes a dominant alleles different from a recessive alleles?

How are dominant and recessive genes?
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.

Explain segregation of alleles using pea plants?
if the pea plant has 2 recessive alleles then the plant is gonna come out short.but if it has 1 recessive and one dominant allele then the plant turns out tall, because the dominant allele can be present without the recessive allele.
What is the pedigree of a rare recessive phonotypr determined by a recessive allele?
this question makes no sense.
What is the difference between a dominant trait and a recessive trait?
A dominate trait will most likely take over the recessive.
A pair of dominant or recessive alleles makes you?
I can't work any thing
