- which of the following statements about the haploid-diploid system of sex determination is true?
- in plant cell cytokinesis, the two daughter cells are separated by the formation of a ---made from the fusion of --- vesicles carrying cell wall materials.
- a fundamental principle of the chromosome theory of inheritance involves the chromosome composition of cells. most eukaryotic cells are diploid, containing chromosomes that are found in ----pairs. during the process of ----, the two member of each pair segregate into different daughter nuclei.
- in animal cells, cytokinesis is accomplished by the formation of a ---composed of ----filaments.
- sex determination systems that are controlled by the environmental temperature are seen in what group of animals?
- during---, pairs of sister chromatids become attached to kinetochore microtubules which emanate from opposite poles of the cell.
- during anaphase, each chromatid moved toward the pole to which it is attached. this movement is caused by the shortening of the ----

- a human cell contains two main types of chromosomes: 1 pairs of sex chromosomes and
- in many insect species, sex is determined by the ratio between---chromosomes and the number of ---- sets
- the ----gene on the Y chromosome plays a key role in causing the development of male characteristic
- place these cells in the correct order in which they are involved in spermatogenesis, starting with the earliest at the top
- which of the following organelles play a role in protein modification and trafficking?
- an ----refers to the physical location of a gene
- the life cycles of plant species alternate between haploid and diploid generations. the haploid generations called the-----, whereas the diploid generations called the-----
- the meaning of the term chromosome can differ depending on the stage of the cell cycle we are observing. during .....phase of the interphase and early stage of M phase, a chromosome refers to a pair of sister chromatids( a dyad). however, at the end of M phase and during ....phase of interphase, a chromosome refers to a monad which contains the equivalent of one chromatid.

- in a ---cell, each type of chromosome is a member of a pair.
- in ----of meiosis, the bivalents(which are also termed tetrads) are aligned along the center of the cell.
