BIOL 133 CHAPTER 13 | COMPREHENSIVE BIOLOGY STUDY GUIDE, PRACTICE
QUESTIONS & ANSWERS 2026/2027
The most common time individual assortment occurs is when genes are ____?
A) Linked
B) Close Together
C) Unlinked
D) On non-sister chromatids of homologues - correct answer ✔✔C) Unlinked
What is the difference between karyotype and a karyogram?
A) Karyotypes and cartograms are terms that are used interchangeably to describe chromosome
mapping
B) Karyotypes describe the number of chromosomes and what they look like (size bands and centromere
placement). Karyograms are the study of the whole set of chromosomes arranged in pairs by size, and
position of the centromere.
C) Karyograms describe the number of chromosomes and what they look like( size bands and
centromere placement). Karyotypes are the study of the whole set of chromosomes arranged in pairs by
size, and position of the centromere.
D) Karyotypes are unstained chromosomes in interphase or prophase. Karyograms are stained
chromosomes from metaphase. - correct answer ✔✔B) Karyotypes describe the number of
chromosomes and what they look like (size bands and centromere placement). Karyograms are the study
of the whole set of chromosomes arranged in pairs by size, and position of the centromere.
Combination of alleles that independently assort is usually higher than the number of chromosomes
because:
A) gene linkage
B) segregation
C) jumping genes
D) crossing over
E) translocation - correct answer ✔✔D) crossing over
A karyogram that contains 23 pairs of chromosomes with a different pair for the 23rd pair would
describe a(n)
A) autosomal pait
B) male
C) female
D) disorder - correct answer ✔✔B) male
What do so many geneticists focus on studying term-7yeast, fruit flies, nematodes, mice or the small
plant Arabidopsis?
A) These pest organisms result in millions of dollars of damage and hurt the economy.
B) They are ideal for modeling human diseases since they have all the same organs.
C) They have multiple features that allow for cheap, fast and efficient manipulation of genes and
chromosomes.
