LSUE Biology 1001 - Final QUESTIONS WITH ANSWERS
RATED A+
heterozygous for the trait and able - A carrier of a genetic disorder who does not show symptoms
is most likely to be _____ to transmit it to offspring
genetics and the environment - The individual features of all organisms are the result of
the hybrid offspring of a cross are the P1 generation - which of the following statements
regarding cross breeding and hybridization is false
8% - According to scientists, about what percentage of men currently living in Central Asia may
be descended from the Mongolian ruler Genghis Khan
applies to all sexually reproducing organisms - Research since Mendel's time has established that
the law of segregation of genes during gamete formation
the alleles for color and vision segregate independently during gamete formation - Imagine that
we mate two black Labrador dogs with normal vision and find that three of the puppies are like
the parents, but one puppy is chocolate with normal vision and another is black with PRA
(progressive retinal atrophy, a serious disease of vision). We can conclude that
XX - The sex chromosome complement of a normal human female is
Most individuals carrying a lethal dominant allele have the disorder and die before they
reproduce, whereas individuals carrying a lethal recessive allele are more likely to be healthy and
reproduce - Which of the following statements best explains why dominant alleles that cause
lethal disorders are less common than recessive alleles that cause lethal disorders
Incomplete dominance supports the blending hypothesis - Which of the following statements is
false?
1/6 + 1/6 = 1/3 - Using a six-sided die, what is the probability of rolling either a 5 or a 6
Most human genetic diseases are treatable if caught early - Which of the following statements
regarding genetic testing is false
0 black eyed; 1 orange eyed - All the offspring of a cross between a black eyed mandelien and an
orange mendelien have black eyes. What is the expected phenotypic ratio of a cross between two
orange eyed medneliens.
anatomical or molecular homologous structures - What evidence is used to determine the
branching sequence of an evolutionary tree?
, the bottleneck effect - genetic drift from a disaster that drastically reduces population size is
called
disruptive selection - A rabbit population consists of animals that are either dark on top or very
light on top. The color pattern is not related to sex. No rabbit shows intermediate coloration
(medium darkness). This pattern might result from
heritable traits that promote reproduction become more frequent in a population from on
generation to the next - Which sentence best describes the true nature of natural selection
artificial selection - broccoli, cabbages and brussel sprouts all descend from the same wild
mustard and can still interbreed. These varieties were produced by
The evolve through genetic drift and other chance processess - A lot of your DNA is inherited
"junk": It does not code for any protein and has no known function in gene regulation. How do
nucleotide sequences of "junk DNA" evolve
maintain two phenotypes in a dynamic equilibrium in a population - Frequency-dependent
selection, as seen in the case of the scale-eating fish in Lake Tanganyika, tends to
mutation - the ultimate source of all new alleles is
Wallace - Who developed a theory of evolution almost identical to Darwin's
p2 - the frequency of homozygous dominant individuals in a population that is in Hardy-
Weinberg equilibrium is equal to
resembled species on the nearest mainland - Darwin found that many of the species on the
Galapagos islands
2pq - Which of the following terms represents the frequency of heterozygotes in a population
that is in Hardy-Weinberg equilibrium
the cells are sparsely scattered through a nonliving matrix - Connective tissue is different from
the other major tissue types in that
adipose tissue - Which of the following is a type of connective tissue?
blood - What kind of connective tissue has an extracellular liquid matrix called plasma
fried egg - Which of the following items has a shape most like a squamous epithelial cell
plasma - The liquid part of the blood that consist of water, salts, and dissolved proteins is known
as
heart muscle - Which of the following is an example of a tissue?
