In this figure, the black circles and squares indicate a genetic disease. Males are represented by squares, females by circles. A. Based on the pedigree in the image, does this gene appear to be inherited in a dominant or recessive manner? Explain your prediction. B. Use the letter B to indicate a diseased allele and the letter b to indicate a normal allele. Predict the genotype of the married female child in generation II. Justify your prediction. C. If the female in generation II has a second child, what is the chance that this child will inherit the disease? Explain.

Expert Solution
Step 1

The pedigree indicates if the DNA is passed down unchanged from generation to generation. It can also aid in the prediction of the traits of future generations of a species. It also aids in determining whether a character is present or absent in the heterozygous or homozygous condition.
