The image above shows a sample of cells in an onion root. What process is occurring?

Crossing Over
Cancer cells are body cells that have begun to divide quickly and uncontrollably. Which process has malfunctioned in cancer cells?
Mitosis
Meiosis
Diffusion
Metaphase
Dogs have 39 chromosomes in their gametes. How many chromosomes must they have in their skin cells?
39 chromosomes
78 chromosomes
23 chromosomes
46 chromosomes
Which of the following BEST explains why meiosis is necessary for sexual reproduction?
Meiosis increases the chance of fertilization because it produces 4 daughter cells
Meiosis results in offspring with genotypes that are not exact copies of the parents
Meiosis allows chromosomes to exchange genetic material through crossing over
Meiosis makes it possible for the zygote to have the correct number of chromosomes
Which of the following statements is true for mitosis and meiosis?
Mitosis produces 2 diploid cells, while meiosis produces 4 haploid cells
Mitosis produces 4 diploid cells, while meiosis produces 2 haploid cells
Mitosis produces 2 haploid cells, while meiosis produces 4 diploid cells
Mitosis produces 4 haploid cells, while meiosis produces 2 diploid cells
The diagram above shows a process that occurs during meiosis. Which of the following best explains how this process contributes to genetic variation?
Crossing over of homologous chromosomes allows exchange of genes
Independent assortment results in a random number of chromosomes from each parent
Fertilization results in offspring that have a combination of traits from each parent
Mutations result in the emergence of new traits in a population
In meiosis, chromatids might sometimes separate incorrectly, resulting in gametes that have 22 or 24 chromosomes, instead of 23. Which process is being described in this scenario?
Crossing Over
Independent Assortment
Nondisjunction
Fertilization
In cheetahs, dark spots are dominant to light spots. If two heterozygous cheetahs cross, what percent of their offspring will be homozygous?
0%
25%
50%
75%
Instead of writing blood types as:
A / B / O
Some scientists notate blood types as:
IA / IB / i
If people with IAi and IBi blood types cross, what will be the blood types of their children?
25% Type A, 25% B, 25% AB, 25% O
50% Type A, 50% B
50% Type AB, 50% Type O
25% Type A, 25% B, 50% O
