The red color of the flower in peas is dominant in relation to the white. Taken: 1) 1 plant with genotype AA and two with genotype aa; 2) 1 plant homozygous for the dominant trait and 2 heterozygous plants; 3) 2 homozygous red-flowered plants and 1 heterozygous plant. Determine the ratio of genotypes in F4 if the reproductive rate is 8.
1) The ratio of genotypes will not change and will remain the same – 1 (AA): 2 (Aa); 2) 31 (AA): 2 (Aa): 15 (aa); 3) 79 (AA): 2 (Aa): 15 (aa).
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.
