关于基因学testcross

Design a female fly with brown eye (BW) color (keep all other traits as wild-type), and
design a male fly with ebony body color (E; keep all other traits as wild-type). Mate
the two flies.
比例是1:1
请问如何拿到的?

其实这是一个flylab的experiment来得
http://biologylab.awlonline.com/
based on那个问题
那到以下是result
Parents
(Female: BW) x (Male: E)
Offspring
Phenotype Number Proportion Ratio
Female: + 5015 0.5038 1.015
Male: + 4940 0.4962 1.000
Total 9955
2 FLYj 就是两个苍蝇
1个是brown eye (BW) color
另外一个
ebony body color
然后交配
+的意思是wild type
wild type也就是默认的trait
现在就是要想办法如何用test cross来解释ratio 1 ? |
