appear in the text) Inheritance is the process by which traits are passed from parents to offspring. There are two types of inheritance: dominant and recessive. Dominant traits are expressed when an individual has at least one dominant allele, while recessive traits are expressed only when both alleles are recessive. This is known as the principle of dominance. One of the main characteristic that suppresses the development of another alternative characteristic is the dominant characteristic. It overrides the expression of the alternative characteristic in heterozygous individuals.

A genotype refers to the genetic makeup of an organism, which includes all of its genes. It can be defined as the collection of all genes of an individual or of a particular species. It represents the combination of alleles an organism possesses for a specific trait. Therefore, the correct answer is the collection of all genes of an organism.

To identify the genetic symbol of a dihybrid, we need to consider the alleles of two different genes. In the given symbols ♂ AB ♀ AABB, it appears that the male has alleles A and B, while the female has alleles A and B in duplicate (AABB). Therefore, the correct genetic symbol for the dihybrid is AB.

Now let"s complete the text. Inheritance is the process by which traits are passed from parents to offspring. There are two types of inheritance: dominant and recessive. Dominant traits (1) are expressed when an individual has at least one dominant allele, while recessive traits (2) are expressed only when both alleles are recessive. This is known as the principle of dominance. One of the main characteristic that suppresses the development of another alternative characteristic is the dominant characteristic (3). It overrides the expression of the alternative characteristic in heterozygous individuals.
