4) The alleles for a certain gene on the homologous chromosomes (remember, in a homologous pair, one chromosome comes from mom and one from dad), will possibly or certainly be different. Hint: For example, if the gene for eye color is on each homologous chromosome, ask yourself whether the alleles (blue eyes, green eyes, brown eyes, etc.) could possibly be different or would certainly be different for each chromosome.

5) A chromosome with ONE chromatid will make a copy of itself during the S or G1 phase of Interphase.

6) The goal of mitosis or meiosis is to make two exact copies of the cell
8) In prophase I of meiosis or mitosis, the homologous chromosomes come together to make a tetrad.
9) In a tetrad during Prophase 1 or Metaphase I, parts of the homologs (the chromosomes of a homologous pair) switch places in a process called crossing over.

10) There is or is not another interphase before the start of Meiosis 2.

12) In males, the 4 haploid or diploid cells at the end of Meiosis 2 become 4 sperm cells.

Simulating adaptations in a species in this activity, you will discuss in detail the adaptations in a species of rain forest plants. you will build a simulation that explains the changes in the traits of the plant population over 10 years. you will also establish a scientific explanation to justify the changes in the traits of the population, * time to complete: 1-2 hours part a an organism's adaptations are specific to its native environment. an organism that lives in a coniferous forest will have different adaptations compared to an animal that lives in a tropical rain forest. the following graphs show the temperature and precipitation throughout the year for two different forests: a coniferous forest in canada, and a tropical rain forest in belize. evaluate the graphs, and then explain why plants from these two ecosystems will have different adaptations. in your answer, explain the survival challenges that plants face in these two environments.
