Here are the answers to your questions: 1.1.1 If a recessive allele on the X-chromosome is passed on to the offspring it is an example of... A This is an example of sex-linked inheritance, as the gene is located on a sex chromosome (the X-chromosome). 1.1.2 In pea plants, the allele for flower colour (B) is dominant to the allele for lack of colour (b). The allele for tall (T) is dominant to allele for short (t). The genotype for a colourless flower pea plant that is heterozygous for height is: C A colourless flower means the genotype for colour must be bb (recessive). Heterozygous for height means the genotype for height must be Tt (one dominant, one recessive allele). Combining these gives bbTt. 1.1.3 Study the following steps. (i) Extraction of the desired gene from the champion organism (ii) Host organism displays the effect of the desired gene (iii) Desired gene is identified (iv) DNA of a host organism is cut open (v) Desired gene is incorporated into the DNA of a host organism Which ONE of the following is the correct sequence of steps during genetic engineering? C The correct sequence of steps in genetic engineering is: 1. (iii) Desired gene is identified. 2. (i) Extraction of the desired gene from the champion organism. 3. (iv) DNA of a host organism is cut open. 4. (v) Desired gene is incorporated into the DNA of a host organism. 5. (ii) Host organism displays the effect of the desired gene.
