In peas, the yellow color of the seeds A dominates over the green a, and the smooth shape of the seeds B – over the wrinkled b. Pea plants obtained from green smooth seeds are pollinated with pollen from plants obtained from yellow wrinkled seeds. The hybrid offspring consisted of 1/4 yellow smooth seeds, 1/4 yellow wrinkled, 1/4 green smooth and 1/4 green wrinkled. Determine: 1) the genotypes of the parents; 2) what offspring can be expected from an analyzing crossing of hybrids with yellow smooth seeds.
1) Genotypes P: (women) aaBb, (husband) Aabb;
2) from the analyzing crossing of hybrids with yellow smooth seeds, the following offspring can be expected: plants with yellow smooth seeds, green smooth, yellow wrinkled and green wrinkled in a ratio of 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.
