Question

Hello, please answer the following Biology question correctly based on the given answer choices. Please pick the correct "answer-letter"> Please just give the correct answer, I don't need an explanation. Thanks.

Biology Question: "Based on the attached pedigree traces the appearance of a trait through a family. How is this trait inherited?"

Answer Choice Options

A -  through a recessive allele on the X chromosome

B -  through a recessive allele on an autosome

C -  through a dominant allele on an autosome

 

This image is a pedigree chart, commonly used in genetics to track the inheritance of traits through generations. Here's a detailed description:

- **Symbols**: 
  - Squares represent males.
  - Circles represent females.
  - Filled symbols indicate individuals possessing a specific trait.
  - Unfilled symbols indicate individuals not possessing the trait.

- **Generations & Relationships**:
  - The top row represents the first generation with individuals 1 to 4.
  - The mating lines connect individuals 1 & 2, and 3 & 4.
  - The middle row represents the second generation, which are the children of the first generation. They include individuals 5 to 9.
  - The third generation includes individuals 10 to 12, connected to individual 7 and 8.

- **Trait Transmission**:
  - Individuals 1, 4, 5, 6, and 9 have the trait as indicated by filled symbols.
  - The chart shows how the trait may be passed from one generation to the next.

This pedigree can be used to study inheritance patterns, genetic linkage, or calculate risk of trait inheritance in future generations.
