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 the child would be a sufferer of Sickle Cell Anaemia?

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 the child would be a sufferer of
Sickle Cell Anaemia?
