In this family tree, individuals with the trait are shown in black. Circles represent biological females. Squares represent biological males. Is the trait dominant or recessive? Explain your answer.Is the trait sex-linked? Explain your answer. **Title: Analyzing Human Pedigree Charts for Genetic Traits****Introduction**Understanding human genetics often involves studying pedigree charts, which help track the inheritance of traits through generations. This document provides an analysis of a given pedigree chart, highlighting the inheritance pattern of a specific trait.**Pedigree Description**The provided pedigree includes three generations, with individuals colored in black indicating possession of the trait. Males are represented by squares, and females by circles.- **Generation I** - Individual I-1: Male without the trait. - Individual I-2: Female with the trait.- **Generation II** - Individual II-1: Female without the trait. - Individual II-2: Female with the trait. - Individual II-3: Male without the trait. - Individual II-4: Female without the trait.- **Generation III** - Individual III-1: Male with the trait. - Individual III-2: Female with the trait. - Individual III-3: Female without the trait. - Individual III-4: Male without the trait. - Individual III-5: Male with the trait. - Individual III-6: Female without the trait. - Individual III-7: Female with the trait. - Individual III-8: Male without the trait.**Questions and Analysis****A. Is the trait dominant or recessive? Explain your answer.**The trait appears to be recessive. This conclusion is based on the fact that the trait skips generations and appears in individuals with carriers parents, who do not express the trait themselves yet have affected offspring.**Additional Notes**The handwritten notes suggest genetic calculations:- The diagram features equations and possibilities regarding genetic inheritance patterns, such as \( \frac{1}{4} \times \frac{1}{2} = \frac{1}{8} \).- "Recessive" is noted in pink, emphasizing the trait's inheritance pattern.- Notations include sex chromosomes (e.g., X and Y), suggesting exploration of sex-linked traits.**Conclusion**Understanding pedigree charts is crucial in identifying how specific genetic traits are inherited, which can provide insight into medical and biological studies. The discussed chart suggests a recessive inheritance pattern, aiding in predicting and diagnosing genetic conditions.**Figures and Diagrams**Pedigree charts are visual representations that use standardized symbols to denote genders and whether individuals carry the trait in

Pedigree represents the familial representation of individual for a particular trait.1. The trait is recessive. Because there are found skipping of generations. Individuals I- 1 and I-2 are unaffected but the offspring II-6 is affected. That's why it is autosomal in nature. The skipping of generation is not found in the dominant inheritance. That's why it is not a dominant trait. 2. The trait is not sex linked. If it is Y linked, then trait is found in males only. But it is also found in females. If trait is X linked, then II-5 should be affected. II-5 and II-4 should pass X chromosome having trait encoding gene to daughter. And the II-5 is affected if the X chromosome having trait encoding gene. That's why it is not a X- linked trait. The trait is autosomal recessive in nature. Both unaffected parents are heterozygous in nature. They pass the recessive allele to the affected offspring.
