Three recessive genes in dogs are linked on a chromosome. A dog heterozygous for all three recessive alleles is crossed with homozygous for all the recessive alleles in a three-point testcross.
(a) Determine the order of these genes on the chromosome and
(b) calculate the map distances between the genes.
The progeny of the testcross are:
r T W 324
R t w 319
R t W 880
r T w 887
R T W 2376
r t w 2365

QUESTION 16
The stereotype image of Neandertal as a “brutish, ignorant caveman” is based on:
|
his large physical size and stocky, muscular build |
||
|
an early Neandertal skeleton of a crippled, hunched-over individual |
||
|
his thick-boned skull and skeleton, and his physical strength |
||
|
all of the above |
1 points
QUESTION 17
The short, muscular bodies of many Neanderthal
populations, with short arms and legs,
may
indicate that they lived:
|
basically sedentary lives with little activity |
||
|
in cold climates |
||
|
in hot climates |
||
|
lives centered around plant and animal domestication |
||
|

QUESTION 18
The African Replacement Model (arguing that
modern Homo
sapiens
first appeared
in one
place, and then spread out to other parts of the world) suggests
that modern Homo sapiens:
|
evolved in Africa and migrated into the rest of the world replacing all other populations |
||
|
evolved in Africa and migrated directly in to Americas |
||
|
evolved in Europe and migrated to Africa |
||
|
evolved locally in Europe, Africa, and Asia from populations of archaic humans |
1 points
QUESTION 19
The Multiregional Evolution Model (which argues
that modern Homo sapiens could have
evolved/appeared
in several different parts of the world) states that modern
Homo sapiens:
|
evolved in Africa and migrated into the rest of the world |
||
|
evolved only in northern and eastern Europe and migrated into the rest of the world |
||
|
evolved locally in Europe, Africa, and Asia from population of archaic Homo sapiens |
||
|
evolved in North, Central, and South America and migrated into
the rest of the world |
