The inheritance pattern in which a single allele is responsible for a variety of traits?
pleiotropy
What does The presence of an allele for purple flowers will mask the presence of an allele for white flowers mean?
Gene responsible for purple color is dominant over white color.
What type of allele is responsible for causing duchenne muscular dystrophy?
sex linked recessive
What allele is responsible for maintaining sickle cell hemoglobin in African populations?
Balanced Selection
In the pea plants the presence of an allele for purple flowers will mask presence of an allele for white flowers. What does that mean?
Gene responsible for purple color is dominant over white color.
What term define alleles that are alike?
An allele can have two or more variants of a gene that have the same position on the homologous chromosome. The alleles are responsible for alternative characteristics. Two copies of the same allele are called homozygous.
What is allele masked by the dominant allele?
The Allele That Is Covered By The Dominant Allele Is The Recessive Allele.
What is the alternate form of a gene?
The answer is allele
An allele that is dominated or cover up by another allele is called what?
It should be a dominant allele--a dominant allele's trait will be expressed over the recessive allele's trait.
How a genetic disease can suddenly appear in a family with no previous history of the disease?
It could happen in two main mechanisms: 1) the allele responsible for the disease is recessive and so each of the parents are healthy portators of the allele (heterozygous), and all the sons which are homozygous for the allele (i.e. have two copies of the allele), with a frequency of 1:4, will be affected by disease, but not the others (heterozygouses and homozygouses for the good allele or wild type). 2) the mutation responsible for the disease (that acts in a dominant manner) is not present in any of the parents but happens only during the formations of gametes, and so will be transmitted to the son. There are also other mechanisms that are less frequent and more difficult to explain in a few words.
What is a dominent allele?
A dominant allele is an allele that can take over a recessive allele, so if you have a dominant allele and a recessive allele, then the offspring will most likely have a dominant allele over a recessive allele. The dominant allele is expressed over the recessive allele.
Allele that prevents the expression of a recessive allele?
A dominant allele
