Complete Punnett square C for an individual with an AO genotype that mates with another AO genotype individual.

a) explain why a diagnosis of ASD is not possible in young babies. b) Given the current understanding of the concordance of ASD, if one of the children detected in these data was an identical twin, how certain is that the other twin would also meet the diagnostic criteria for ASD?

Sickle cell anemia follows a single-gene pattern of inheritance, with two alleles: one allele (S) produces normal hemoglobin, and the other (s) produces abnormal hemoglobin. Describe the phenotype outcome for each of the three possible genotypes (SS, Ss and ss), with regard to sickle cell anemia and malaria.

BACKGROUND: Sickle cell disease is caused by a change in the gene for hemoglobin, which is the oxygen-carrying protein in red blood cells. Individuals who are homozygous for the sickle cell trait often cannot endure exercise. Individuals who are heterozygous for the trait can have sickle cell attacks under extreme conditions. Normal individuals (genotype: Hbnorm Hbnorm ) have only normal hemoglobin. Homozygous sickle cell individuals (genotype: Hbsc Hbsc ) 'have only sickle cell hemoglobin. Heterozygous individuals (genotype: Hbnorm Hbsc ) have both normal and sickle cell hemoglobin. terry Smith collapsed while running a race for his track team. A doctor said he had a sickle cell attack. Genetic tests were run on several family members. The test results are shown below. An X indicates that form of hemoglobin in red blood cells. PROBLEM: How can you determine the genotypes of people in a family? Subject Normal Hemoglobin Sickle Cell Hemoglobin Jerry Jerry's brother Jerry's younger…

Complete a new Punnett square below, for a woman who is a carrier for sickle cell, who is married to a man who has sickle cell. What are the possible genotypes that you can identify, what is the ratio of phenotypes that are possible, and what is the chance that any of the offspring are affected by sickle cell anemia?

Give only typing answer with explanation and conclusion Travis and Marcy, a Caucasian couple, are pregnant with their first child. Travis has a prior child with cystic fibrosis (autosomal recessive). He has refused to pursue carrier testing but Marcy has had negative carrier testing. Note: Carrier testing can identify 90% of carriers of CF accurately and approximately 1/25 Caucasian's are carriers of CF. What is the chance they will have a child with CF? Group of answer choices 1/964 1/140 1/25 1/209

Explain the differences between an individual homozygous for the sickle hemoglobin allele (HbS/HbS) and one who is heterozygous (HbA/HbS). Consider the hemoglobin molecule, cells, and disease.
