Chapter 14, Problem 2SA
Summary Introduction
Introduction:
The pedigree chart helps to depict the complete history of the pattern of inheritance of genetic disease from one generation to another generation. The inheritable genetic disease is either autosomal dominant or recessive or sex-linked based on which the probability of disease in a future generation can be predicted.

Pedigree analysis is necessary when studying human inheritance patterns because . a. humans have more than 20,000 genes b. of ethical problems with experimenting on humans c. inheritance in humans is more complicated than it is in other organisms d. genetic disorders occur only in humans
When Gregor Mendel first proposed his theories on genetics, they were not recognized. This was because:
A.
Charles Darwin didn't agree with Gregor Mendel's theories.
B.
The current theory was that traits from parents blended together in their offspring.
C.
Gregor Mendel proposed that individuals could change their physical traits during their lifetime and pass those new traits on to their offspring.
D.
Scientists believed there were 5 nucleotide bases, not 4 nucleotide bases.
According to the video “The Biology of Skin Color”, why is it that the allele coding for darker skin did not evolve to protect us from skin cancer?
A. Because skin cancer isn't harmful
B. Darker skin did develop to protect us from skin cancer
C. Because skin cancer usually develops after an individual's reproductive years, so it doesn't affect the ability for someone to pass on their genes
D. Because skin cancer usually develops before an individual's reproductive years, so it doesn't affect the ability for someone to pass on their genes
