The Phenotypic Effects of Crossing Over in a Diheterozygous Genotype AaBBCc

Crossing over is a process in which homologous chromosomes exchange genetic material. In a diheterozygous individual with genotype AaBBCc, crossing over between genes A, B and C will produce four different types of gametes: AABBCC, AABBCc, AaBBCC, and AaBBCc. Without crossing over, only two types of gametes will be produced: AABBCC and AaBBCc. The types of gametes that will be more in crossing over are AABBCc and AaBBCC. This is because the exchange of genetic material between the homologous chromosomes creates new combinations of alleles, making these types of gametes more likely to be produced (Liang et al., 2016).
The genes A, B and C are located on different chromosomes. In diheterozygous individuals, each gene will be present on two different chromosomes, one from each parent. Crossing over occurs when the homologous chromosomes exchange genetic material during meiosis, leading to the production of new combinations of alleles. Cont…
