Aa. This is the heterozygous condition. Two alleles, one of which is dominant and masks the expression ( to varying degrees ) of the other allele. 'A' dominant and 'a' recessive. So, if the trait in question is the recessive allele the dominant allele masks its expression and the organism is a ' carrier ' of the trait and can pass it on to progeny.
Gregor Mendel discovered the dominant and recessive mode of genetic inheritance.
Wrinkled peas are recessive, smooth peas are dominant.
He studied dominant and recessive genes. He studied pea plants and the traits that they obtained from previous generations.
Gregor Mendel's experiments with pea plants helped establish the principles of inheritance, showing that traits are passed down from parents to offspring in predictable patterns. He discovered the concept of dominant and recessive traits, as well as the idea of genetic segregation and independent assortment. Mendel's work laid the foundation for modern genetics and our understanding of how traits are inherited.
Hemophilia is broken into three subcategories; Hemophilia A, Hemophilia B, and Hemophilia C. These subcategories designate a person as having a deficiency of one of three specific clotting proteins. Hemophilia A is the deficiency of the protein called Clotting Factor VIII. Hemophilia B is the deficiency of Clotting Factor IX. Hemophilia C is the deficiency of Clotting Factor XI. "Royal" hemophilia is simply a reference to Hemophilia B and is therefore a result of a deficiency in the Clotting Factor IX protein. It is sometimes called the royal disease because it has been known to have been passed through some royal families throughout history.
Most mutations in eukaryotes exhibit a recessive inheritance pattern because they typically involve changes in a single gene, and the presence of a normal copy of the gene can often mask the effects of the mutated gene. This means that individuals with one normal and one mutated copy of the gene will not show the effects of the mutation, leading to a recessive inheritance pattern.
A recessive trait cannot be dominant over a dominant trait. Dominant traits are always expressed over recessive traits in heterozygous individuals because they mask the expression of the recessive 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.

A unibrow is not determined by a single gene with simple dominant or recessive inheritance. It is influenced by multiple genes and can vary in expression. Factors like genetics and hormonal levels can affect the presence of a unibrow in individuals.
