In the context of genetics, two of these can refer to different alleles of a gene, which are variations that occur at the same locus on a chromosome. For example, one gene may have an allele for brown eyes and another for blue eyes. Additionally, two different mutations can exist within a single gene, potentially affecting its function or expression. These variations contribute to genetic diversity and can influence traits in an organism.
Two gametes, each carrying one copy of the A gene and one copy of the B gene.
We call a gene that has two different alleles heterozygous.
no. The ABO system and Rh blood group are already decided the moment sperm meets ovum. It is decided by the gene we have. For ABO classification, to put it simply people with A blood type has two A gene or one A gene plus one O gene. People with B type have two B gene or one B gene plus one O gene. People with AB type has one A gene and one B gene. O type has two O genes. A father passes one of his blood gene to his child and a mother passes one as well that the child now has two, and the combination is what decides the child's blood type. Bombay type is a very rare blood type different from A, B, or O. You can only have it if your family has a very rare gene, or in other words, if one of your family has it.
A gene with two different alleles is called a heterozygous gene. This means that an individual has inherited two different versions of the gene, one from each parent.
hh X Hh You get two recessives; hh and hh and two heterozygous plants; Hh and Hh

Each person has two alleles for an autosomal gene, one inherited from each parent. These two alleles together determine an individual's genotype for that gene.
Basically, because there are two sexes. One gene allele is on one chromosome from dad and the other allele is on the chromosome from mom. If more than two alleles for a trait, only two can be represented in the genome of the organism.
If the Tr are the genes, then one will be TT, and one will be rr, two will be Tr.
A carrier. This is usually a disease that requires two parts of a gene. The faulty gene is the recessive gene, and the healthy gene is the dominant gene. If two people with one dominant and one recessive gene each have a child they have a 25% chance of producing a child with two dominant genes, thereby resulting in that child having the disease.
two tall genes or one tall gene and one short gene
A recessive gene is one that is only expressed if an individual has two copies of that gene. This means that the trait associated with the recessive gene is not visible unless an individual inherits two copies, one from each parent. If an individual inherits only one copy of a recessive gene, the dominant gene will be expressed instead.
An indiviual letter in a punnett square representing a gene is called an allele. The two genes ( one from each parent ) together is a genotype. There isn't really two forms of a gene.
