What is analyzing crosses?

Analyzing mating is the type of mating in which a test individual with a dominant phenotype is mated with an organism homozygous for the recessive allele (analyzer). If the test individual is homozygous (AA), then the offspring from such a cross will be uniform and no splitting will occur. A completely different result will be obtained when crossing in the event that the studied organism is heterozygous (Aa). In the offspring, cleavage will occur and two phenotypic classes will be formed, and their ratio will be strictly 1: The result clearly proves the formation of two types of gametes in one of the parent individuals, i.e., its heterozygosity.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
