In tomato, the genes that determine the high growth of the plant (A) and the round shape of the fruit (B) are linked and localized on one chromosome, and the genes that determine the short growth and pear-shaped shape are in the autosome. A heterozygous tomato plant was crossed, which has a high growth and a round fruit shape, with a low pear-bearing plant. Determine the genotypes and phenotypes of the offspring of the parents, the gametes formed in meiosis, if there was no chromosome cross.
1) Genotypes of parents – AaBb and aabb. 2) Gametes: AB, AB; ab. 3) Genotypes and phenotypes of offspring: AaBb – tall round-fruited plants, aabb – dwarf pear-bearing plants.
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.
