These alleles show their effect on the phenotype whenever they are present in the genotype?
Dominant alleles carry traits or characteristics that will show no matter what.
Recessive alleles carry traits where you must be homozygous for the recessive trait in order for it to show.
Dominant alleles are represented by capital letters (EX: R or M)
Recessive alleles are represented by lower case letters (EX: r or m)
In order for a dominant allele to show, you can have either RR or Rr, since it is dominant.
However, in order for a recessive allele to show, you MUST have rr.
Hope this helps!
What else can I help you with?
What phenotype is produced by AB genotype?
The genotype AA represents a homozygous dominant genotype. The capital letter "A" represents the dominant allele, while the lowercase letter "a" would represent the recessive allele. If both dominant alleles are present in a genotype (homozygous dominant) then the phenotype is "A" phenotype. If one dominant allele and one recessive allele are present (heterozygous dominant) then the phenotype is "A". Finally, if both recessive alleles "a" are present (homozygous recessive) then the phenotype is "a". Therefore, the answer to your question is the genotype AA would result in an "A" phenotype because the genotype is homozygous dominant.
What are alleles for a particular trait that are always expressed are said to be?
Dominant alleles. Dominant alleles will always be expressed in the phenotype, even if only one copy is present in the genotype.
Which is the FALSE statement a Phenotype determines genotype b Combination of alleles are known as genotype c A gamete will only receive one allele or another from a pair?
The FALSE statement is "A phenotype determines genotype." In reality, it is the genotype that determines the phenotype, as the genetic information (allele combinations) present in an individual's DNA influences their observable traits.
The detectable traits of an organism as determined by what alleles are present is the what?
The detectable traits of an organism as determined by what alleles are present is the phenotype. Phenotype is the observable characteristics of an organism, such as its physical appearance or behavior, which are influenced by both genetic and environmental factors.
Do both alleles of a gene pair make up an organisms genotype?
If by gene pair, you mean the two copies of each gene present in a diploid cell, then yes. Both alleles make up an organisms genotype, though they might not both be expressed in the phenotype, if one is recessive for instance.
Using the terms dominant recessive explain the difference between genotype and phenotype?
No, I think you have your terms confused.The terms "dominant" and "recessive" are applied to alleles of a genotype. A genotype is an expression (using upper- and lower-case letters) that shows what alleles an organism has for a particular locus. The two alleles (in most cases) inherited (one from mother and one from father) can either be dominant or recessive. The recessive allele is not fully expressed in the presence of the dominant allele and is only expressed when there are two recessive alleles. The genotype could be called "recessive" I suppose if the genotype is homozygous recessive. But remember that two recessive alleles as a genotype is only one possibility - in which case you can't say the "genotype is recessive".The phenotype is dependent on the genotype. If present, the dominant alleles (in simple Mendelian genetics) will determine the phenotype - what the organism's trait or characteristic is. The phenotype will never be what is coded by the recessive allele unless the genotype is two recessive alleles.
What phenotype is produced by AB genotype?
The genotype AA represents a homozygous dominant genotype. The capital letter "A" represents the dominant allele, while the lowercase letter "a" would represent the recessive allele.

Can you see all genetic variation?
No. Genotype is the combination of genes present in an organism. It consists of alleles whose visible characteristics is called phenotype. An organism's phenotype is visible and not the genotype as you just can't see a person and tell what kind of genes are present in the organism.
Do both alleles of a gene pair make up an organisms genotype?
If by gene pair, you mean the two copies of each gene present in a diploid cell, then yes. Both alleles make up an organisms genotype, though they might not both be expressed in the phenotype, if one is recessive for instance.
How would you describe the alleles in a heterozygous genotype?
In a heterozygous genotype, an individual possesses two different alleles for a particular gene, with one being dominant and the other recessive. The dominant allele is expressed in the phenotype, while the recessive allele is not unless two recessive alleles are present.
What are alleles and what are the two forms?
Alleles are different versions of a gene that can code for different traits. The two forms of alleles are dominant and recessive. Dominant alleles mask the effects of recessive alleles when present together in an individual's genotype.
In what alleles can be observed in the phenotype?
you mean phenotype, and its dominant alleles
How do you distinguish between genotype and phenotype heterozygous and homozygous and dominant and recessive?
Genotype is the organism's full heredity information that may or may not be expressed. Actual observed properties are the phenotype. The phenotype is dependent on the genotype. Genes are homozygous when the same allele (form of the gene) inherited from both parents is the same. When different forms of the same gene are inherited from parents, they are heterozygous. Dominance refers to the relation between alleles of a gene. When two alleles of a gene combine, the dominant one then determines the trait that is expressed. In order for a recessive trait to be expressed, both alleles need to be recessive.
What is genotype at the Q gene?
Genotype at the Q gene refers to the specific combination of alleles present at the Q gene locus in an individual's DNA. This genotype determines the individual's genetic makeup and can influence their phenotype or physical characteristics.
