一、自由组合问题的解题规律自由组合问题是若干个分离问题的叠加.凡是属于自由组合规律的遗传题,都可以利用分离规律的相关规律来求解.解题时先将自由组合的问题分解成一个一个分离定律的问题,然后将结果有序组合.即先分解,再组合.二、自由组合问题的解题技巧1.熟练解决分离定律中的A_问题在分离定律问题的解决上学生感觉费时和经常出错的是A_的自交和A_的自由交配问题.熟练解决A_的问题,就可以提高做题速度和准确率.A_代
First, the free combination problem solving law Free combination problem is the superposition of a number of separation problems.All those belonging to the free combination law of genetic problems, can use the law of separation law to solve the problem. Into a law of separation of a problem, and then the results of an orderly combination, that is, the first decomposition, re-combination of two free combination problem solving skills 1. Skilled in resolving the A_ problem in the law of separation In the separation of law problem solving students Feeling time-consuming and often mistakes is A_ self-intersection and A_ of free mating problem.Software to solve the problem of A_, you can improve the speed and accuracy of the problem .A_ on behalf of
