In peas, the yellow color of the seeds is determined by the gene A, green – a, the smooth form of the seeds – B, wrinkled – b, the presence of antennae in the plant – C, their absence – c. From crossing plants with genotypes (females) AaBb x (male) aabb offspring were obtained: 26% with genotype AaBb, 27% – Aabb, 23% – aaBb and 24% – aabb. When crossing plants with genotypes (females) BbCC x (male) bbcc, offspring with genotypes 49% BbCc and 51% bbcc were obtained. Determine: 1) which genes belong to the same linkage group; 2) what phenotype the offspring will have from the following crosses: a) (wives) AaCcx (husband) aaCc; b) (women) bbCc x (husband) BbCc; c) (women) AaBbCc x (man) aabbCc.

1) Genes B and C belong to one linkage group; 2) a) plants with yellow seeds and antennae, with green seeds and antennae, with yellow seeds and without antennae and with green seeds and without antennae in a ratio of 3: 3: 1: 1;
b) plants with wrinkled seeds and antennae, with smooth seeds and antennae, with wrinkled seeds and without antennae and with smooth seeds and without antennae in a ratio of 1: 1: 1: 1;
c) plants with yellow smooth seeds and tendrils, with green smooth seeds and tendrils, with yellow wrinkled seeds and tendrils, with green wrinkled seeds and tendrils, with yellow wrinkled seeds and without tendrils, with green wrinkled seeds and no tendrils in a ratio of 2: 2: 1: 1: 1: 1.

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.
