Evaluation of competence – practical skills

7.2.1. Draw up the mitotic cycle scheme and, using relevant symbols (2p2c), match the number of chromosomes and molecules of DNA for the mitosis phase.

7.2.2. Draw up the scheme of meiosis and,using relevant symbols (2p2c), match the number of chromosomes and molecules of DNA for the meiosis phase.

7.2.3. Draw up and explain stages of spermatogenesis

7.2.4. Draw up and explain stages of oogenesis

7.2.6. Solution of standard tasks:

7.2.1. Genes which should get into gear in the period remained not active. Whether it will be reflected on a mitosis course?

7.2.2. If at a female organism with the Mm genotype a gene – the M at meiosis got to an ovum where the m gene will get?

7.2.3. Why at light microscopy of a chromosome aren't visible in interphase, but are found during a mitosis?
