By the end of this course, you should be able to: answer a range of questions covering the content, concepts and skills in the module 2a. Telophase: During Telophase, single-stranded coiled chromosomes start to uncoil. a cell that is not involved in the production of gametes (Gametes can be sperm or egg cells). Tay-Sachs disease is an autosomal recessive trait. These have been made according to the specifications (H020, H420, H021, H421) and cover all the relevant topics for examination in May/June. Segregation increases the genetic variation of the gametes and thus offspring (derived from gametes). Also, even if all of the parents’ characteristics that are passed down to offsprings are favourable, exact replication of genetic would decrease genetic variation in a population. COMMUNITY FEEDBACK.

Lesson 2 | Technologies to assist disorders HSC Biology Module 5: Heredity and the start of Year 12 Biology is a sharp twist towards genetics and more complex ideas about health and disease. This means that, under normal conditions, Adenine only bonds with Thymine and Cytosine only bonds with Guanine. We will explore what homologous pairs actually mean later as we get into the steps of mitosis. explain a range of causes of disorders by investigating the structures and functions of the relevant organs, for example: â hearing loss â visual disorders â loss of kidney function. Also note that a chromosome is made up of DNA and protein. Also, the centrosomes begins to move and align up at opposite ends of the cell’s equator. For independent assortment, it is the process where alleles specifying for different genes in non-homologous pairs will assort themselves independently during metaphase I. However, up until now, we have only briefly mentioned the terms mitosis and meiosis under the categories of asexual and sexual reproduction respectively. ABOUT THESE NOTES. By increasing genetic variation, the offspring of the next generation would have different characteristics which would increase the probability of the species’ population surviving the event of a sudden change in the ambient environment. Jack, their two-year old son, may be red-green colour blind. For example, in humans, we have 23 sets of chromosomes. A model of enzyme activity is shown. HSC Physics â Module 5 â Advanced Mechanics. This is because each of the double-stranded chromosomes that contains two alleles for different genes have separated during Anaphase II. The allele combinations in each of the two pink chromatids were (bhc and bhc). This question assessed Module 9.1 skills content and was generally well answered.

Crossing a tall plant and short plant yielded a 50% population of short offspring. Apart from the chromatids, the centrosomes have also been duplicated. (1 mark), In a variety of sunflower plants, the allele for thick stems, is dominant over the allele for thin stems. Unlike Mitosis, Meiosis starts off with a germ cell rather than a somatic cell. This would therefore mean the independent alignment of the chromosomes between non-homologous pairs on the equator of the cell. In this Beginner’s Guide, we will cover Module 5: Heredity and its topics: Topic 1: Reproduction and Cell Replication; Topic 2: DNA and Polypeptide Synthesis; Topic 3: Genetic Variation and Inheritance Patterns in a Population . Therefore, independent assortment will determine the alleles for different genes such each of the two haploid cells can inherit which, ultimately, affects the allele for each gene that each gamete can inherit at the end of Cytokinesis II in Telophase II. Module 5: Heredity. In meiosis, one cell splits into two and each of the two cells further splits into two. Beta thalassemia is an inherited blood disorder that reduces the body’s production of haemoglobin. A germ cell is found in the reproductive organ of an organism can undergo meiosis to produce gametes such as sperm and egg cells, depending on the gender of the organism.

You can now see chromosomes in their classic “X” shape under a compound or light microscope. A model of enzyme activity is shown. Crossing a tall plant and short plant yielded a 50% population of short offspring. However, unlike mitosis, meiosis does not maintain the overall number of chromosome number throughout the process. The gene for cystic fibrosis is recessive. Therefore, the gametes cells that are produced at the end of meiosis are NOT diploid but haploid cells. Of course, they are joined together via chemical bonds too. Keep in mind that during the segregation process in Anaphase II prepares for each gamete to inherit one allele for each gene from the parent, which is why it is a haploid. ABOUT THESE NOTES.
