With the whitefish blastual cell during interphase, prophase, metaphase, anaphase, telophase and cytokinesis when is cell furrow, chromosomes, duplicated chromosomes,mmitotic spindle and nucles present and visable?

During meosis I __________ are segregated, with each pair of chromosomes __________ Crossing over ___________

Select true or false for each of the following statements regarding anaphase I. Sister chromatids remain attached at the centromeres. Answertruefalse Homologous chromosomes remain attached at the centromeres. Answertruefalse Sister chromatids are pulled apart. Answertruefalse Homologous chromosomes are pulled apart. Answertruefalse Chiasmata are broken. Answertruefalse

Which statement best describes the process of crossing over? Homologous chromosomes pair up, and non-sister chromatids exchange genetic material.   Homologous chromatids pair up, and non-sister chromosomes exchange genetic material.   Pairs of homologous chromosomes are divided in half and distributed randomly into new haploid cells.   Pairs of homologous chromatids are divided in half and distributed randomly into new diploid cells.

The nuclear envelope is broken into smaller components. Kinetochore microtubules are assembled and are connected to kinetochores. Name: The chromosomes become aligned in a plane at the cellular equator. Name:

If a variety of seaweed reproduces only through mitosis, this would be considered is "asexual reproduction" true or false?

Which of the following occur during Meiosis I? Select all that apply Spindle tension aligns the chromosomes in the center of the cell Homologous chromosomes align in the center of the cell Ploidy is changed from diploid to haploid Sister chromatids are separated

mitosis nuclei resides in the nucleus karyotype autosomes haploid In dividing parent cell; in the parent cell. Male and female gametes at fertilization forms a homologs Microscopic observations showed that during fertilization, the unite, providing evidence that genetic material resides in the cell membrane Brightly staining, threadlike bodies within the nucleus were termed of these bodies could be traced through cell division. chromosomes diploid A image can reveal abnormalities in meiosis of eggs and sperm ; the movements gametes contain a single set of chromosomes. The fusion of zygote. the number of chromosomes in daughter cells remains the same as in the the number of chromosomes in daughter cells is half that of Two chromosomes that match in size, shape, and banding when isolated and stained are is an image of an individual's chromosomes arranged in homologous pairs. This chromosome number and structure nondisjunction

Draw a cell in meotic metaphae 1-label the mitotic center, centrioles,polar microtubules, and kinetochore microtubules.
