Just because an allele is dominant does not mean that it is necessarily common.
How common a version of a gene is (i.e. its frequency in a population) depends on how it affects an organism's chance of surviving to reproduce. Natural selection may favor a recessive allele of one gene and a dominant allele of another.

Does sexual life cycles differ with respect to the relative timing of meiosis and fertilization?
Yes, sexual life cycles can differ based on the relative timing of meiosis and fertilization. In some organisms, such as animals, meiosis and fertilization occur separately and alternately, resulting in a diploid-dominant life cycle. In contrast, in some algae and fungi, meiosis and fertilization can occur in close succession, leading to a haploid-dominant life cycle.
For a mutation to affect evolution it must occur in?
For a mutation to affect evolution, it must occur in the DNA of reproductive cells (sperm or egg cells) so that it can be passed on to offspring. Mutations that occur in somatic cells (non-reproductive cells) do not directly impact evolution as they are not inherited by future generations.
Huntington's disease will occur in individuals who receive a gene from one parent only. Therefore the gene for Huntington's is referred to as .?
dominant
What does recessive allele mean?
Recessive allele disorders are just as they sound - they are disorders that are a result of a prevalent recessive allele in one's genetic makeup. A recessive allele disorder will rarely occur since it is dependent on the crossing of two heterozygous parent cells, but it can lead to interesting consequences. An example of a recessive allele disorder is hemophilia - the body's inability to clot blood - and it has affected much of the European royalty in history, such as Queen Victoria of Great Britain.
What is the diminent and recessive?
In genetics, a dominant trait refers to a gene that will be expressed if present, even if only one copy is inherited. A recessive trait, on the other hand, requires two copies of the gene to be expressed. Dominant traits mask recessive traits when both are present in an organism's genetic makeup.
When two different alleles occur together the one that is expressed is called?
Dominant.
Does evaporation occur in the freezer?
no it doesnt
What boundary does tensional stress occur?
it doesnt
Can a MD. diagnose mental disorders?
Generally No. Only a psycologyst should, but that doesnt mean it doesnt occur.
What type of gene causes traits that are more likely to occur?
a dominant gene.
Why does cellular respiration only occur in plant cells?
it doesnt.
How does an allele trait in an organism?
An allele causes a trait by either being dominant orrecessive or example, allele A will occur over allele a because it is dominant.
Does combustion in plants occur in the roots?
no it doesnt but i dont know how LOL!
What happens in meiosis 1 that doesnt occur in meiosis 2?
dna is copied
What is the difference between a dominant gen and a recessive gen?
A dominant gene is always expressed in an individual's phenotype when present, while a recessive gene is masked by a dominant gene and only expressed when two copies are present. Dominant genes are represented by capital letters (e.g., A), while recessive genes are represented by lowercase letters (e.g., a) in genetic notation.
What happens if vegetables don't get enough sun?
they die obviously....becoz photosynthesis doesnt occur.
Is the dominant trait always expressed?
A dominant gene will be expressed if paired with a recessive gene or with a dominant gene for the same trait. For example, the trait for brown eyes (BB) is dominant over blue eyes (bb) - thus an offspring Bb will express brown eyes, just as BB.
