What is when an individual has two copies of a dominant allele?
The person is considered to be heterozygous dominant. Heterozygous refers to having to of the same allele (AA or AA). dominant means AA not AA
What is a heterozygous recessive?
Homogeneous recessive is two like genes that express a recessive trait.
What is the phenotype of an individual with one allele for dimples and one allele for no dimples?
a example of a gene
What is a complete dominance?
Complete dominance is a genetics concept used in heterozygous alleles. The dominant allele completely suppresses expression of the recessive one so that a homozygous dominant and a heterozygous individual are phenotypically indistinguishable.
What is the alternative forms or genetic information for a trait are called?
This is generally the definition of an allele. An allele is an "alternate form of a gene". For each gene there may be many alleles. For example (simplistically) the gene which makes the pigment in your eyes (ie which gives you your eye colour) has a brown, green and blue allele. On each of the two chromosomes (one from your mother and one from your father) you can have either the same allele (homozygous) or a different allele (heterozygous). In the case of a heterozygous gene the dominate allele is expressed. In some cases (co-dominance) both alleles are expressed.
What is a fact for homozygous?
an individual containing 2 copies of the same allele for a particular trait located at similar positions on paired chromosomes
What is when an individual has two copies of a dominant allele?
The person is considered to be heterozygous dominant. Heterozygous refers to having to of the same allele (AA or AA). dominant means AA not AA
When both allele of the gene are the same what is the individual?
homozygous
In sickle-cell disease an allele produces red blood cells with an abnormal shape which affect many other traits in the same individual. What genetic behavior does this describes?
pleiotropy
What is called when the homologous chromosomes in an individual have the same allele for a certain gene?
Homozygous
If an individual has the copies of a trait the same what is it called?
Homozygous
What is homozygous in biology?
individuals who are homozygous carry two copies of the same allele, if u know what i'm talking about.
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.
An individual who is homozygous is what?
It is a genetic similarity between two organisms.
If you have two copies of the same allele are considered to be for that traits whereas if you have two different alleles you are considered to be for that trait?
homozygous, heterozygous
What is another word for homozygous?
Having two copies of the same allele. An organism as such can be called homozygote Answer: It is also called a purebreed.
Does a dominant allele mask a ressessive allele?
In diploid organisms (those with two copies of each gene carried on separate chromosomes), one of the copies of a given gene may differ from the other copy of the same gene on the twin chromosome. In some cases one version of the gene (the dominant allele) has the effect of 'masking' the activity of the other (the recessive allele); that is, the presence of the dominant allele negates the effect of the recessive allele on the organism's phenotype. There are many mechanisms which can cause this phenomena, and it depends on the particular genes involved, but a simple model is one where the recessive allele is a biochemically inactive version of the dominant allele. In this case the dominant allele would mask the effect of the recessive allele by providing an active version of the gene. The dominant phenotype would be the one which shows the downstream effects of this activity, and the recessive phenotype one which shows the downstream effects of a lack of activity. The dominant allele is said to 'mask' the recessive allele because only one copy is required to result in an elimination of the recessive phenotype, whereas all copies of the gene must be the recessive allele to result in the recessive phenotype.
