LSUE BIOLOGY 1001 FINAL EXAM PAPER 2026
QUESTIONS WITH VERIFIED SOLUTIONS
◉ 8%. Answer: 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. Answer: 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. Answer: 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. Answer: 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. Answer: 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. Answer:
Which of the following statements is false?
◉ 1/6 + 1/6 = 1/3. Answer: 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.
Answer: Which of the following statements regarding genetic testing
is false
◉ 0 black eyed; 1 orange eyed. Answer: 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. Answer: What
evidence is used to determine the branching sequence of an
evolutionary tree?
◉ the bottleneck effect. Answer: genetic drift from a disaster that
drastically reduces population size is called
