Exam 3: Chromosome Transmission During Cell Division and Sexual Reproduction

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

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?

During this phase of the cell cycle the microtubules of the spindle fiber attach to the kinetochore:

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

The yeast Saccharomyces cerevisiae produces haploid cells of two mating types, a and $\alpha$ , which are morphologically similar. Cells of opposite mating types can mate. Saccharomyces cerevisiae is a(n) ___________ species.

Cell division in prokaryotic cells is called ________, while in eukaryotic cells it is called ________.

If an organism has five pairs of chromosomes, how many chromosomal combinations are possible at metaphase I of meiosis?

During this phase of the cell cycle the chromosomes line up in the center of the cell:

Organelles are __________.

In plants, the haploid generation is called the ______ and the diploid generation is called the __________.

The process where two gametes fuse with each other in the process of fertilization to begin the life of a new organism is called

During this phase of the cell cycle the separated sister chromatids are considered independent chromosomes:

During sexual reproduction, each parent contributes one set of chromosomes. Members of a pair of chromosomes (one from each parent) are called __________.

During this phase of the cell cycle, the sister chromatids are formed:

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

A bivalent contains how many chromatids?

Which microtubule type is paired to its correct function?

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

What represents the correct order of events during prophase I?

If the gametes of an organism are different morphologically, they are said to be __________.
