o   ABc

o   abC

o   aBC

o   Abc

o    H. AbC

 

 

Question 2 of 10

Which is likely to disrupt the function of the most genes: a 500kb deletion, a 500kb inversion, or a 500kb translocation?

 

o   Deletion

o   Inversion

o   Translocation

 

 

 Question 3 of 10

The most common time individual assortment occurs is when genes are ________?

 

o   unlinked

o   close together

o   linked

o   on non-sister chromatids of homologues

 

 

Question 4 of 10

Combination of alleles that independently assort is usually higher than the number of chromosomes because

 

o   segregation

o   gene linkage

o   jumping genes

o   crossing over

o   translocation

 

 

Question 5 of 10

Serious disease syndromes are associated with trisomy of chromosome 21 (Down syndrome), 18 (Edwards syndrome) and 13 (Patau syndrome).

What is the result of trisomy of the other chromosomes?

 

o   no disease symptoms

o   minor disease symptoms

o   disease symptoms with varying severity based on genetic background

o   lethal early in development

 


Question 6 of 10

What is the difference between a karyotype and a karyogram?

 

o   Karyotypes and karyograms are terms that are used interchangeably to describe chromosome mapping

o   Karyotypes describe the number of chromosomes and what they look like (size bands and centromere placement). Karyograms is the study of the whole set of chromosomes arranged in pairs by size, and position of the centromere

o   Karyograms describe the number of chromosomes and what they look like (size bands and centromere placement). Karyotypes is the study of the whole set of chromosomes arranged in pairs by size, and position of the centromere

o   Karyotypes are unstained chromosomes in interphase or prophase. Karyograms are stained chromosomes from metaphase

 

 

 Question 7 of 10

Nondisjunction during meiosis I will result in ________.

 

o   n

o   n-1

o   n+1

o   n+1 and n-1

o   n, n-1, and n+1

 


Question 8 of 10

Why do so many geneticists focus on studying yeast, fruit flies, nematodes, mice or the small plant Arabidopsis?

 

o   These pest organisms result in millions of dollars of damage and hurt the economy.

o   They are ideal for modeling human disease since they have all the same organs.

o   They have multiple features that allow for cheap, fast and efficient manipulation of genes and chromosomes.

o   They are some of the few organisms in which mutations can be generated.

 

 

Question 9 of 10

A karyogram that contains 23 pairs of chromosomes with a different pair for the 23rd pair would describe a(n)

 

o   autosomal pair

o   male

o   female

o   disorder

 

 

Question 10 of 10

Your study partner is confused. “I thought Watson and Crick discovered genes – who are all these other people?”

Help out by matching each discovery with the scientist(s) who made it.

 

o          A. Watson and Crick

o          B. Sutton and Boveri

o          C. Punnett

o          D. Mendel

o          E. Morgan
