A commonplace in genetics is the relationship between recombination frequency and crossover value. Generally speaking, ______.

A:recombination frequency may be directly obtained according to phenotypic ratios, but crossover value cannot be directly obtained according to phenotypic ratios B:crossover value may be replaced by recombination frequency or chiasm frequency you get from the observation under microscope when genetic distance is considerably short C:crossover value may be replaced by recombination frequency when genetic distance is as a medium value, not too long and not too short D:recombination frequency will be very different from crossover value when there is a third locus in between the two loci you analysed

类MyClass的定义如下：
class MyClass

public：
MyClass（　）
MyClass(int i)value=new int(i)；
int*value；
；
若要对value赋值，则下面语句正确的是( )。

A:MyClass my；my.value=10； B:MyClass my；*my.value=10； C:MyClass my；my.*value=10； D:MyClass my(10)；

如下程序的输出结果是( )。
public class Test

void printValue(int m)

do
System.out.println("The value is"+m);

while(--m ＞ 10 )

public static void main(String args[])

int i=10;
Test t= new Test（　）;
t.printValue(i);

A:The value is 8 B:The value is 9 C:The value is 10 D:The value is 11

已知Value是一个类，value是Value的一个对象。下列以非成员函数形式重载的运算符函数原形中，正确的是

A:Value operator+(Value v，inti)； B:Value operator+(Value v=value，inti)； C:Value operator+(Value V，int i=0)； D:Value operator+(Value v=value，int i=0)；
