Alleles are the alternative forms of a gene. A dominant allele, whenever present, expresses its phenotypic character. However, a recessive allele needs to be present in a pair, in order to express the phenotype . Haploid organisms contain one allele while diploid organisms contain two alleles present on the chromosome.

Part 1 - With use of Punnett diagrams discuss how the results of experiments carried out by Austrian monk Gregor Mendel on pea plants brought about the Law of Dominance, the Law of Segregation, and the Law of Independent assortment. Part 2 - In humans, the gene that produces the disease Sickle Cell Anaemia is recessive to the gene for healthy haemoglobin production. a) How can two phenotypically healthy parents have a child who suffers from Sickle cell Anaemia? In your answer use suitable letters to show the genotypes of the parents and construct a Punnett diagram to show all the possibilities of the children's genotypes. b) Based on the outcome of your Punnett diagram, state and explain the probability of a child being a sufferer of Sickle Cell Anaemia and the probability of a child not suffering from the disease. c) If an individual who suffers from Sickle cell disease has a child with someone who is healthy (and not carrying the sickle cell gene), what is the probability that…

Fruit flies are very useful model organisms that have been used to study genetics. One mutant recessive trait in fruit flies is called "eyeless" because it causes flies to have no eyes. Cross an eyeless fly with a homozygous normal fly. a. Draw the Punnett square. b. What is the genotyoe ratio of the offspring? c. What is the phenotype ratio of the offspring? d. What genetic problem is this? (monohybrid, dihybrid or multiple allele)
