Session 2 38 BCR Galactosemia is an inherited disorder in humans. A person with the disorder cannot digest the sugars in milk. The allele for normal digestion (G) is dominant; the allele for galactosemia (g) is recessive. A female who is heterozygous for the galactosemia trait and a male who has galactosemia have a child. Describe how this disorder could have been passed on in the family. In your response, be sure to ■39 Nitrogen compounds are a part of all organisms. What happens to the nitrogen in an organism after it dies? A B C D It is destroyed by decomposition. It is recycled and used by other organisms. It remains trapped in the organism’s tissues. It is all used up by the time the organism dies. • identify the genotype of the father (2)MDB00880 • complete a Punnett square to show the possible genotypes and phenotypes of the child • describe the probability that the child will inherit galactosemia • describe all the possible genotypes and phenotypes of the father’s parents; explain your answer Write your answer in your Answer Book.
