FULLY CORRECT
⫸ A body cell is in the longest stage of its life cycle. The cell grows,
synthesizing proteins and increasing in size. Eventually, the cell will
grow too large to carry out normal activities and begin mitosis. Which
phase is the cell in? Answer: G1
⫸ During meiosis, sister chromatids are separated and move toward
opposite ends of the cell as the centromeres that hold them separate.
Which of the following processes will begin next? Answer: Telophase II
⫸ A wolf's diploid number of chromosomes is 78. How would the
number of chromosomes in the wolf's body cells compare to the number
of chromosomes in its gametes? Answer: Its body cells would have 78
chromosomes, and its gametes would have 39 chromosomes.
⫸ Some organisms undergo asexual reproduction through mitosis, while
others reproduce sexually, and their cells undergo meiosis to produce
gametes. If there were drastic changes in temperature in an ecosystem,
which process do you predict would be most beneficial to a species?
Answer: Meiosis: it increases genetic variation, which helps ensure the
species will survive.
, ⫸ In pea plants, the allele for round seeds is dominant to the allele for
wrinkled seeds. If a plant that is heterozygous for seed type is crossed
with one that has only homozygous wrinkled seeds, what percent of their
offspring would you expect to have wrinkled seeds? Answer: 50 percent
⫸ In fruit flies, the allele for ebony body color is recessive to the allele
for brown body color. In a generation of fruit flies with 103 offspring, 51
males and 52 females had ebony bodies. Which of the following is the
best conclusion you can make about the parents of this generation?
Answer: Both parents were homozygous with ebony bodies.
⫸ Codominance is a form of inheritance in which two different alleles
for a gene are both expressed, and neither allele is dominant over the
other. One example of codominance is blood type in humans; the alleles
for type A blood and type B blood are codominant. If a man who is
homozygous for type A blood and a woman who is homozygous for type
B blood have children, what would you expect to find in the children?
Answer: The children will all have type AB blood.
⫸ The pedigree chart below shows the individuals in a family who
exhibit a certain trait. Based on the information in the chart, which of the
following provides the best evidence that this is a recessive trait?
https://imgur.com/TNbEXjo Answer: Couple 3-4 in the 2nd generation
produced children who do not show the trait.
⫸ A plant breeder found a species of flowering plant with very
attractive flowers growing wild in a field and she thought it would
appeal to her customers. Some of the plants of this species had red
