Introduction: Race refers to a geographically isolated breeding population, which commonly shares certain character in greater frequencies compared to other populations of that species. However, they no become isolated reproductively from other population of the same species.
Answer to Problem 1SQ
Correct answer: c. Race is socially constructed and is not a biological concept.
Explanation of Solution
Reason for the correct answer:
Today the racial categories are socially constructed boundaries. However, they have no basis particularly in biology and science in general.
Option c. is given as “Race is socially constructed and is not a biological concept.”.
Hence, the correct answer is option c.
Reasons for incorrect answers:
Option a. is given as “Racial traits change very suddenly across geographic regions”.
Racial traits changes happen very gradually across geographical regions. Therefore, option a is incorrect.
Option b. is given as “Racial categories explain a very high percentage of genetic variation”.
Racial categories are not accounted for
Option d. is given as “Personal genomic research supports racial categories”.
Since each person has biological variations this option does not support the racial categories. Therefore, option d is incorrect.
Hence, options a., b., and d. are incorrect.
The true statement about race is race is a socially constructed concept and is not a biological concept.
