List the characteristics of Fungi (ii) Draw a large labelled diagram of a mould Fungus such as Bread Mould (Rhizopus) (b) How are Fungi useful to man? (c) How would you test for the presence of reducing sugar in a piece of bread?

Step 1: Determine dominance and assign alleles. When a pure-breeding red pod plant is crossed with a pure-breeding green pod plant, all offspring produce red pods. This indicates that red pod colour is dominant over green pod colour. Let R represent the dominant allele for red pods. Let r represent the recessive allele for green pods. Step 2: First cross (Parental generation to F1 generation). Pure-breeding red pod plant genotype: RR Pure-breeding green pod plant genotype: rr Cross: RR × rr |c|c|c| Gametes & R & R \\ r & Rr & Rr \\ r & Rr & Rr \\ All F1 offspring have the genotype Rr and the phenotype red pods. Step 3: Second cross (F1 self-pollination to F2 generation). The F1 offspring (Rr) are allowed to self-pollinate. Cross: Rr × Rr |c|c|c| Gametes & R & r \\ R & RR & Rr \\ r & Rr & rr \\ Step 4: F2 generation genotypes, phenotypes, and comparison with observed results. From the Punnett square for the F2 generation: Genotypic ratio: 1 RR : 2 Rr : 1 rr Phenotypic ratio: 3 Red pods : 1 Green pods Observed results: Total offspring = 580 (red pods) + 206 (green pods) = 786 plants Expected number of red pods = (3)/(4) × 786 = 589.5 ≈ 590 Expected number of green pods = (1)/(4) × 786 = 196.5 ≈ 196 The observed results (580 red, 206 green) are very close to the expected 3:1 phenotypic ratio (approximately 590 red, 196 green), confirming the Mendelian inheritance pattern where red is dominant over green.
