1. The problem asks to assess the effect of selective breeding on food crops. Selective breeding is the process where humans choose plants with desirable traits to reproduce, enhancing those traits in future generations. Important rule: Traits are passed genetically, so selecting parents with good traits increases the chance offspring have those traits. Effect: It can increase yield, disease resistance, and adaptability of crops. 2. The problem asks to describe three desired traits in sheep and how they are passed on. Desired traits might be: (a) Wool quality, (b) Disease resistance, (c) Growth rate. These traits are passed on through genes inherited from parent sheep. Selective breeding of sheep with these traits increases the likelihood offspring inherit them. 3. The problem asks to compare and contrast inbreeding and hybridization. Inbreeding: Mating closely related individuals to preserve traits but can increase genetic defects. Hybridization: Crossing genetically different individuals to combine traits, often increasing vigor and diversity. Summary: - Inbreeding increases homozygosity, risks defects. - Hybridization increases heterozygosity, often improves traits. q_count:3
