Step by step
Solved in 3 steps
- Determining a karyotype is an important clinical method for diagnosing genetic disorders. Explain why it is useful for diagnosing monosomies and trisomies.For an individual expressing the dominant phenotype, explain why you must list two possible genotypes.An allele that is not expressed in the heterozygous condition is
- If I got an A from my father and a O from my mother for my genotype. How would my phenotype be expressed? What is my blood type? Explain your reasoning for both answers.Define multiple allelesA mother is heterozygous for the X-linked gene for colorblindness and also heterozygous for the autosomal inherited sickle cell anemia. She is married to a man who can see color normally and who is heterozygous for sickle cell trait. Using b (colorblind), B (normal color), S (normal hemoglobin), s (sickle cell), answer the following: a. What are the genotypes of the parents? b: What is the probability of having a child who is both color blind and has sickle cell anemia?
