The white color of the corolla in the phlox dominates over the pink. A homozygous plant with a white whisk is crossed with a pink-colored plant. Hybrid plants of Pr were grown from the seeds obtained, which were then pollinated and the seeds obtained were sown. 1. How many types of gametes can the original mother plant form with a pink halo? 2. How many different genotypes will be in F1? 3. How many different phenotypes will be in F2? 4. What will be the ratio of phenotypes and genotypes in the F2 generation?
1 – one type of gametes (a); 2 – in the first generation there will be one genotype (Aa); 3 – in the second generation there will be two phenotypes; 4 – the ratio of genotypes will be (AA, 2 AA, aa), phenotypes (¾ will be white, ¼ will be pink).
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
