pleiotropy
A heterozygous individual who has one allele for a disease but is not affected by it is considered a carrier. Carriers can pass the disease allele to their offspring but do not exhibit the symptoms themselves. This is common in genetic disorders that follow a recessive inheritance pattern.
In a relationship where one allele is completely dominant over another in genetic inheritance, the dominant allele will always be expressed in the phenotype, while the recessive allele will only be expressed if both alleles are recessive. This is known as complete dominance.
Simple dominance is a concept in genetics where one allele (gene variant) masks the expression of another allele at the same locus. This results in the dominant allele being expressed phenotypically, while the recessive allele is not expressed. This type of inheritance pattern is common in traits like eye color or hair texture.
Codominance is a genetic inheritance pattern where both alleles for a trait are fully expressed in the phenotype of an individual. This means that neither allele is dominant or recessive, and they both contribute to the observable trait. In contrast, in other forms of genetic inheritance, such as complete dominance or incomplete dominance, one allele may be dominant over the other, leading to a different expression of the trait.
Having a dominant and recessive allele is known as Mendelian inheritance, named after Gregor Mendel, the scientist who first described it. In this type of inheritance, the dominant allele masks the expression of the recessive allele in heterozygous individuals.

Incomplete Dominance
Roan is an example of incomplete dominance inheritance in cows and bulls. In this type of inheritance, the heterozygous individual will display a phenotype that is a mixture of the two homozygous genotypes. In the case of roan cattle, the roan color pattern is expressed when a black coat color allele and a red coat color allele are present.

Complete inheritance refers to a situation where one allele is completely dominant over another in a gene pair, resulting in the dominant allele always being expressed in the phenotype, while the recessive allele remains hidden. This type of inheritance follows Mendel's laws of inheritance, where dominant traits mask the expression of recessive traits in an individual's phenotype.
A dominant pedigree refers to a pattern of inheritance in which a dominant allele on a gene is expressed in the phenotype of an individual, masking the effects of a recessive allele. This results in the dominant trait being exhibited in individuals who inherit at least one copy of the dominant allele.
A heterozygous individual who has one allele for a disease but is not affected by it is considered a carrier. Carriers can pass the disease allele to their offspring but do not exhibit the symptoms themselves. This is common in genetic disorders that follow a recessive inheritance pattern.
Its a pedigree. A pedigree shows the inheritance of a genetic disorder within a family and can help to determine the inheritance pattern and whether any particular individual has an allele for that disorder.
