-somatic cells have the diploid number of chromosomes.
-the haploid number of chromosomes in humans is 23.
-the diploid number of chromosomes in humans is 23.
-Each human parent contributes eleven and a half pairs of chromosomes to the zygote.
Each human parent contributes eleven and half pairs of chromosomes to the zygote.
In which organ will meiosis occur for the human female?
In animals, ____ occurs during the production of the egg and the sperm.
Which of the following statements is NOT correct when cells undergo meiosis?
-Meiosis ensures that the chromosome number remains constant generation after generation.
-meiosis ensures that each generation has a different genetic makeup than the previous one.
-meiosis ensures that each newly formed daughter cell receives the same number and kinds of chromosomes.
-meiosis results in four daughter cells.
Meiosis ensures that each newly formed daughter cell receives the same number and kinds of chromosomes.
Which of the following statements is NOT correct about meiosis?
-It involves on duplication of chromosomes.
-It requires two divisions.
-It results in four daughter cells.
-The four daughter cells have one of each pair of chromosome.
-The four daughter cells have the same number of chromosomes as the parent cell.
The four daughter cells have the same number of chromosomes as the parent cell.
Prior to meiosis I, DNA replication occurs, and each pair of chromosome has two sister chromatids. Therefore, each chromosome can be called a ________.
When homologous chromosomes come together and line up side by side, it is termed _____.
When does synapsis and crossing-over occur in meiosis?
In ___, pairs of homologous chromosomes line up at the equator of the spindle.
What is the exchange of genetic material between non-sister chromatids called?
Following synapsis during meiosis I, the homologous chromosomes separate. This separation means that ______.
one chromosome from each homologous pair reaches each haploid daughter cell
During ____, homologous chromosomes separate and move to opposite poles of the spindle.
During ____, daughter cells will form, each containing only one chromosome from each homologous pair.
During ____, the sister chromatids are lined up at the equator.
During ______ , a spindle appears while the nuclear envelope fragments and the nucleolus disappears. Only one set of sister chromosomes from each pair of homologous chromosomes is present.
During ______ , the sister chromatids separate and move toward the poles.
In ______ , the spindle disappears as the nuclear envelopes form. The plasma membrane furrows to give two complete cells, each of which has the haploid, or N, number of chromosomes. Each chromosome has one chromatid.
The production of sperm in males is called ______ .
Which of the following statements about oogenesis is NOT correct?
-Once its started it continues to completion.
-It will form one large egg cell and three smaller polar bodies.
-It produces only one cell that goes on to become an egg.
-It will not continue unless the secondary oocyte is fertilized.
Once its started it continues to completion.
Which cell during oogenesis must be fertilized by a sperm if it is to become a mature egg?
How many chromosomes are present in the human secondary spermatocyte?
Which of the following cells represents a way to discard unnecessary chromosomes while retaining much of the cytoplasm in the egg?
Which of the following cells, when combined, will result in a diploid fertilized egg?
-sperm cell plus a polar body
-sperm cell plus a primary oocyte
-sperm cell plus an egg cell
-spermatid plus and egg cell
-spermatid plus a primary oocyte
sperm cell plus an egg cell
Which of the following statements is NOT correct about human spermatogenesis?
-It only occurs in the testes of males.
-It undergoes two cell divisions.
-It results in four haploid cells, each with 46 chromosomes.
-Once started it goes to completion.
-It results in four sperm, all of equal size.
It results in four haploid cells, each with 46 chromosomes.
