    color more understandable. These genes are known as “EYCL1‚ which is also referred to as gey gene‚ and EYCL3‚ also known as bey2 gene. For the bey 2 gene if a person has a brown allele then they will have brown eyes. In the gey gene the green allele is dominant over the blue allele‚ but it is still recessive next to a brown allele” (Forensic Science International). Another factor that plays in determining eye color is melanin. Melanin is known as a “product of cells in the human body” (National Institutes

Study for Bio 97 Notes for Finals (ADL HW 10) Item #1 Recombination occurs when combinations of alleles not found in either parent are placed into gametes during meiosis in the F generation. The F can be thought of as having been formed 1 1 from two haploid “input” gametes. In this case‚ the F is a dihybrid with AB on one chromosome and ab on the other 1 chromosome

    system for the differing pigmentations? Was green the dominant allele or was purple the dominant allele? Or does Brassica rapa exhibit incomplete dominance which would result in a brown colored pigment? An experiment was needed in order to determine how the pigment was inherited. It was expected that if the allele which provided the green pigment was dominant than all the F1 generation would be green. Alternatively‚ if the allele which is responsible for purple is dominant‚ than all the F1 plants
