during cell division, centromeres have separated, and chromatids are pulled apart, becoming chromosomes. which stage of mitosis does this describe? (2 points)

prophase

anaphase

metaphase

telophase

what would happen to a body cell that was interrupted during mitosis? (2 points)

cells would begin dividing uncontrollably.

chromosomes would not separate into two nuclei.

cytokinesis would occur more rapidly.

the cell would not be able to grow any further.

its body cells and gametes would both have 18 chromosomes.

its body cells and gametes would both have 36 chromosomes.

its body cells would have 18 chromosomes, and its gametes would have 36 chromosomes.

in which scenario would mitosis be least desirable in terms of a species' survival? (2 points)

a species has little energy to devote to reproduction

a species is unable to travel far to find a mate

a species has to adjust rapidly to a changing environment

a species is preyed upon by numerous successful predators

50 percent

100 percent

0 percent

25 percent

two fruit flies produce the following generation: 91 flies with recessive white eyes (rr) and 91 flies with red eyes (rr or rr). what can you conclude about the parents of this generation? (2 points)

one parent was heterozygous for eye color and the other was homozygous with red eyes.

both parents were homozygous with red eyes.

one parent had white eyes and the other was heterozygous for eye color.

both parents were heterozygous for eye color.

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. the alleles for red fur and white fur in cattle are codominant. if a homozygous red cow and a homozygous white bull mate, what would you expect to find in their offspring? (2 points)

they will all have white fur.

their fur will be a mixture of red and white hairs.

their fur will be pink.

they will all have red fur.

the pedigree chart below shows the individuals in a family who exhibit a certain trait. based on the information in the chart, what conclusion can be drawn? (2 points)

a diagram of a pedigree chart. at the top of the chart are two individuals: one indicated by a green circle and one by a green square. at the next level down, the green circle is paired with a black square and the green square is paired with a black circle. from the green circle/black square pairing, there are three offspring: a green circle, a green square, and a black square. from the green square/black circle pairing, there are eight offspring: three black circles and four black squares. two of the black squares are identical twins. one of the black circles is paired with another black square. this pairing produced one green circle.

it is a recessive trait.

it is a dominant trait.

individual 12 is homozygous for the trait.

individual 12 exhibits the trait.

a plant breeder sells purple violets which can be pp or pp for the purple color. she crosses two purple violets. of the four plants that result, one is white and three are purple. what can she conclude about the parent plants? (2 points)

one of the parents' genotype must have been pp and the other pp.

one of the parents' genotype must have been pp and the other pp.

both of the parents' genotype must have been pp.

both of the parents' genotype must have been pp.
