A cell can be described as being homozygous for a particular gene when there are identical genes on a pair of chromosomes (humans have 23 pairs). Under these conditions, we would see the expression of the gene under the homozygous condition. If the cell had a heterozygous condition, then there would not be identical genes found in the chromosome pair.
What else can I help you with?
Dominant gene plus Dominant gene?
It would be definite that you have that gene or trait.
What type of gene has Identical alleles?
A homozygous gene has identical alleles. Homozygous means the individual has two copies of the same allele for a particular gene.
An individual with two identical alleles of a gene is?
An organism that has two identical alleles for a trait is known as a homozygote or a homozygous organism.
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.
When both parents contribute to the gene pair are recessive the pair is referred to as the?
The gene pair is referred to as homozygous recessive. This means that both copies of the gene are recessive, resulting in the expression of the recessive trait.
What is recessive gene and dominant gene?
A dominant gene is always expressed if present, and the recessive gene is only expressed with the homozygous recessive genotype. For example, if the dominant gene is red (represented by the letter R) and the recessive gene is white (represented by the letter r), then a homozygous dominant organism's genotype will be RR, and its phenotype will be red. If the organism is homozygous recessive, then the genotype will be rr and the phenotype will be white. If the organism is heterozygous, then the genotype will be Rr, and the organism will be red.
What term describes a gene with two dominant alleles that are expressed at the same time?
Co-dominance.
Dominant gene plus Dominant gene?
It would be definite that you have that gene or trait.
Two identical alleles for a particular gene is what?
Having two identical alleles for a particular gene is known as homozygous. This means that both copies of the gene are the same, either both dominant or both recessive. Homozygosity can result in a specific trait being expressed, depending on the nature of the alleles.
What type of gene has Identical alleles?
A homozygous gene has identical alleles. Homozygous means the individual has two copies of the same allele for a particular gene.
An individual with two identical alleles of a gene is?
An organism that has two identical alleles for a trait is known as a homozygote or a homozygous organism.

In order for a recessive trait to be expressed, both alleles need to be recessive.
Can a individual carry a gene that is not expressed?
not usually, most books fit into the normal genres: mystery, fiction, nonfiction, adventure etc. I believe this person is referring to "genes," not "genres." To answer the question, then: yes, you can have genes that are not expressed. Recessive genes, for example, will not be expressed in heterozygous individuals; they will only be expressed in homozygous recessive individuals. For example; if you have the genotype Aa, the recessive gene - "a" - will not be expressed because the genotype contains a dominant allele, and the dominant allele will always be the one expressed. The only way that the "a" allele will be expressed is, again, if you are homozygous for that recessive gene (your genotype would be aa).
When both parents contribute to the gene pair are recessive the pair is referred to as the?
The gene pair is referred to as homozygous recessive. This means that both copies of the gene are recessive, resulting in the expression of the recessive trait.
What is a gene combination for a single trait?
homozygous dominant, heterozygous, or homozygous recessive
What are recessive expressed in?
homozygous organisms
Can two dominant genes equal a recessive gene?
it could but then u would be deformed but usually it cant
