Make sure to distinguish between chromosomes and the following phases of cell division (G1 phase, prophase, metaphase, anaphase, telophase, cytokinesis). Indicate the chromosome equation and chromosome number of the parent cell and the daughter cells. *S phase and G2 phase purposefully excluded Consider a diploid organism that follows the XX-XO mode of sex determination. Normally, there are 7 chromosomes in its somatic cell. The chromosomal composition is as follows: Chromosome I is a large acrocentric chromosome Chromosome II is a large telocentric chromosome Chromosome III is a small telocentric chromosome Chromosome IV (X chromosome) is a medium submetacentric chromosomearrow_forwardcell type: 9) Label the figure below.

An organism with two of each kind of chromosome is said to be: (3) tetraploid (1) haploid (2) diploid (4) polyploid. In multicellular organisms, mitosis results in: (1) reproduction (2) growth and repair (3) sperm and egg production (4) fertilization. If an organism produced an egg that had 20 chromosomes, the body cells of that organism should have: (1) 10 chromosomes (2) 20 chromosomes (3) 30 chromosomes (4) 40 chromosomes. 11) is what helps us grow and is why we are all unique!

Be sure to draw the correct number of chromosomes and the correct number of chromatids per chromosome.
