yellow round grains, yellow wrinkled grains, green round grains, green round grains; The genotypes are: yyrr yyrr yyrr yyrr; The ratio of gametes is: 3:

Anonymous users2024-02-06Hehe, this involves two laws, one is the law of separation and the other is the law of free combination. "The ratio of round grains to zou grains is 3:1, and the ratio of yellow to green grains is 1:
1" can be concluded that in the parent, the colors are yy and yy, so that the yellow is 3:1 to green, and the round wrinkles are rr and rr, so that the round wrinkles can be 1:1.
Then the parents are yyrr and yyrr. Then F1, there are yyrr, yyrr, yyrr, yyrr, yyrr, yyrr, yyrr, "let the yellow round pea in F1 cross with the green Zou pea" yellow round grain, yr, there are yyrr, yyrr, two kinds. Green corn grains only yyrr.
I don't know how to count the rest of this, after all, I haven't been in contact for many years. I don't know how to calculate 3:1:
1. I don't think it's right.

Anonymous users2024-02-05The genotype of the yellow round grain in F1 is YYR 1 3 is YYRR 2 3 is YYR The genotype of the green wrinkle is YYRR The segregation ratio of the F2 phenotype is Yellow Round:Yellow Wrinkle:Green Circle:
Green wrinkle = 2:1:2:
1 This ratio is calculated as the ratio of all yellow round grains in F1 to green wrinkled grains. The title of the book is to calculate the hybridization of a plant with yellow round grains and green wrinkled grains, and there are two kinds of hyyrr and yyrr hybridization, and the result is 1:1
1:1 yyrr hybridizes with yyrr yellow circle:green circle = 1:
1. I don't have a lot of time, if you have any questions, you can ask the Life Sciences team directly, they will be very enthusiastic to help you.

Anonymous users2024-02-04Gamete segregation ratio: The proportion of gametes carrying different alleles due to the separation of alleles when heterozygotes form gametes. The gamete ratio of one pair of alleles is 1 1, and the gamete ratio of two alleles is 1 1 1 1 The phenotype refers only to traits related to segregation, such as the roundness and wrinkles of peas, the long wings and residual wings of fruit flies, etc.
Genotype refers to the sum of the genetic makeup in a cell or organism, or the combination of genes that control a trait. Well, I'll tell you the answer when I think about it.
1.The eardrum of the human ear is a thin, elastic membrane like the membrane of the drum, and when sound waves pass through the ear canal to the eardrum, the eardrum vibrates and transmits this (vibration) to the cochlea >>>More
Dude, the Tao Te Ching is not a classical Chinese text, especially the first chapter, which is the general outline of the Tao Te Ching, which cannot be translated in modern Chinese, and you have to rely on your own comprehension to understand it, everyone looks at it and understands things differently, you want a ready-made, basically impossible. Even if there is a so-called translation, it has long since changed its taste, and what you see is not the most standard, or even irrelevant.
Step 1: Write the chemical equation for the reaction.
For example: cuso4+bacl2=cucl2+baso4 Step 2: Write the substances that are easy to ionize with water and easily in ionic form (only strong electrolytes can be written), and insoluble substances or substances that are difficult to ionize and gases are still expressed by chemical formulas (including weak electrolytes and non-electrolytes, which cannot be written as ionic equations). >>>More
