An exception to the dominant and recessive pattern in genetics is incomplete dominance, where neither allele is completely dominant over the other. This results in a blending of traits in the offspring. An example of this is in snapdragon flowers, where a red flower crossed with a white flower produces pink flowers.

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 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.


How are dominant and recessive alike?

Both dominant and recessive traits are terms used to describe the inheritance pattern of a specific gene. They are both part of Mendelian genetics, where dominant traits mask the expression of recessive traits when present together. Both dominant and recessive alleles can be carried by an individual, with dominant alleles being expressed over recessive ones.


Why is incomplete dominance considered an exception to Mendel's principles of inheritance?

Incomplete dominance is considered an exception to Mendel's principles of inheritance because it results in a blending of traits, rather than the dominant trait completely masking the recessive trait as seen in Mendelian genetics. This leads to a unique inheritance pattern where neither allele is fully dominant, breaking the traditional rules of dominant and recessive traits established by Mendel.


Can a recissive gene be dominant?

No, a recessive gene cannot be dominant. In genetics, dominant genes are expressed over recessive genes when present in an individual's genotype. This means that if a gene is recessive, it will only be expressed if an individual inherits two copies of that specific recessive gene.

Which traits oberved were dominant and recessive?

In genetics, dominant traits are those that are expressed when an individual has one or two copies of the dominant allele, while recessive traits are only expressed when an individual has two copies of the recessive allele and no dominant allele present. Dominant traits often mask recessive traits in heterozygous individuals.


Can a recissive gene be dominant?

No, a recessive gene cannot be dominant. In genetics, dominant genes are expressed over recessive genes when present in an individual's genotype. This means that if a gene is recessive, it will only be expressed if an individual inherits two copies of that specific recessive gene.


A genetics tool that uses letters to represent dominant and recessive alleles?

A punnet square uses letters to represent dominant and recessive alleles.


Are the terms dominant and recessive considered antonyms?

Yes, in the context of genetics, the terms dominant and recessive are considered antonyms. Dominant refers to a trait that is expressed when an individual has one or two copies of the dominant allele, while recessive refers to a trait that is only expressed when an individual has two copies of the recessive allele.


How do genetics represent h dominant and Recessive allele?

A dominant genotype is represented as DD or Dd but with many different letters. The DD is a homozygous dominant, while the Dd is the heterozygous dominant. Recessive is always represented as dd or rr or whatever letter you want to use. It is always homozygous recessive. There can never be a heterozygous recessive.


Chromosome that has both dominant and recessive gene?

A chromosome can have both dominant and recessive genes for a specific trait, but only one gene will be expressed in an individual. The dominant gene will be expressed over the recessive gene in a heterozygous individual. This is known as the principle of dominance in genetics.


What can you predict by using a punnett square and the principles of probability?

You can very well give an educated guess on what the genetics of the offsring you are calculating but you need to know what the mother and fathers genetics traits are and if they are homozygous dominant, homosygous recessive, heterosygous dominant, or heterzygous recessive.
