Abstract:
It was studied for the heredity laws of keratin membrane and sugar content in semi-leafless vegetable pea. The results showed that keratin membrane character is controlled by two genes. F1 displays large keratin membranes in all fresh pods; F2 has three phenotypes, i.e. large keratin membrane, small keratin membrane and no keratin membrane with the ratio of 9:6:1. Sugar content is quantitative character fitting normal distribution. 'Xucai 1', a new semi-leafless vegetable pea variety with high yield and quality was successfully bred according to the laws. Its fresh pods taste delicious. Its extremely developed tendrils can be sold as top grade Longxu vegetable. The tender stems and leaves are also high quality vegetable.

Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal chance to...
