Summary Introduction
To review:
The given pedigree chart.
Introduction:
A pedigree chart represents the inheritance of a trait/character/disease from one generation to another in a family. In a pedigree chart, males are represented as squares while females are represented as circles. Affected females/males are shown by shaded boxes. Connected symbols show a married couple or children. The pedigree chart is given below:

- Construct pedigree charts using the inheritance of hemophilia in figure 92 (page 113). This is X-linked inheritance so you are required to label XX for females and XY for males. The gene responsible for the trait is represented by the superscript which should be specified in the legend.arrow_forwardThe genotype of EB27 and EB67 are unknown. Based on pedigree, what are the most likely genotype of each individual?arrow_forwardWhich of the Pedigree diagrams below is most likely to show a family with Sickle Cell Anaemia?arrow_forward
- Help me create a pedigree of this information: Pedigree analysis: Generation 1: Normal parents (AA x AA) Generation 2: Carrier parents (AA x AS) Generation 3: Affected child (AS x AS) Generation 4: Affected grandchild (SS) This pedigree has two normal parents in the first generation. Second generation carriers carry the sickle cell trait from one parent. The disease is 25% more likely to be inherited in the third generation if both parents have the 'S' allele. If both parents have the 'S' allele, their children will have sickle cell anemia in the fourth generationarrow_forwardPorphyria is a genetic disorder caused by the inability to properly metabolize a component of hemoglobin. King George III is suspected to have been afflicted with this disorder. Assume that both George and his Queen suffered from this disorder and they had one afflicted child and one normal child. Is porphyria inherited in a dominant or recessive fashion? What must be the genotype of both George and his Queen? Using punnett square, show ALL work used to achieve your answer.arrow_forwardThe pedigree below shows the phenotypes of the ABO blood groups and Rhesus factors [positive (+) and negative (-)] for several members of a family.

Figure 2 i) Identify the blood group of individual 2 and state your reason. ii) If Individual 6 marries a woman with the same blood group, state the phenotype of their children. iii) If Individual 6 has the same genotype with his grandfather, give the genotype of individual 5.arrow_forwardThe pedigree shown below shows the inheritance of cystic fibrosis, a disorder that causes severe damage to the lungs and digestive system. Individual 5 shows no family history of cystic fibrosis and is considered to be homozygous for the normal allele. What is the probability that individual 10 is a carrier for the allele leading to cystic fibrosis?arrow_forwardQueen Victoria had 1 (Leopold) out of four male offspring with hemophilia. What was the probability of this scenario? Hemophilia is known as "The royal disease" because many of the European royal families had members afflicted with it. A really famous case was Queen Victoria's (1819-1901) descendants who spread the disease across Europe, from Spain to Russia.
