Select the correct answer.
a family has a y-linked disease that affects the father. what is the chance of a male offspring inheriting the same disease?
a 100%
b. 50 %
c. 25%
d. 0%

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.

its probably to later but whats the question
