Check all that apply. In prokaryotic cells

A pollen grain in a plant represents the ________.

Which microtubule type is paired to its correct function?

In animals, somatic cells are ________ and germ cells are ________.

What occurs during leptotene of prophase I?

Check all that apply. Sister chromatids are separated during anaphase of

During this phase of the cell cycle the nuclear membrane reforms around the chromosomes.

In plants, spores are produced by the process of ________.

You are studying a diploid organism that has 14 pairs of chromosomes. How many chromatids will a gamete from this organism have?

A karyotype is a(n)

You are studying a new species of plant similar to Mendel's pea plants. You are specifically interested in two genes that are located on two different chromosomes. In this plant, the gene for height has two alleles, T (tall) and t (short). The gene for leaf color has two alleles P (purple) and p (pink). What meiotic products do you expect from diploid cells that are homozyous for the tall allele and heterozygous for the purple allele?

Which of the following would contain genetic material that is 100% identical?

You are studying a diploid organism that has 14 pairs of chromosomes. How many chromatids would this cell have in G2 phase?

You are performing a karyotype for the first time and you forget to add the colchicine. How do you predict this will affect your karyotype?

During this phase of the cell cycle sister chromatids separate and head towards opposite poles of the cell.

The end result of meiosis in animals is ________.
