Imagine that individuals with a certain allele (B) have much greater reproductive success than those without the allele. However, individuals with the B allele also have shorter life spans than those without the allele. How would you predict the allele frequencies in the population will change through subsequent generations

Allelic frequency

Explanation:

The B allele will become more common only if the individuals reach reproductive ages

Since the individuals with allele B have much greater reproductive success therefore once they reach the reproductive age, success to reproduce new individuals will be higher

The offsprings will carry on the allele(B allele) and pass on to the next generation

Even if the parental individuals die because of shorter life span the offsprings produced in each generation will pass on the allele to their subsequent generation  

Schools are being forced to embrace computers. unlike their "digital immigrant" teachers, these students are "digital natives", born into a world where technology is an integral part of everyday life. almost every student has access to a multitude of computers, laptops and tablet devices. it would be crazy to assume an assignment would  notbe written on computer in this day and age.many schools now have a 1-to-1 computer policy, and many districts and states in the united states have mandated computers or ipads across the state for every student,  including los angeles, the second largest school district in the country.but the thing is, when they tried it in la, it wasn't the success they hoped for. that's because the tablets weren't used as much as they expected. rather, it appeared there was a gap between the digital native's love of technology and their use of it in the classroom.this conflicted relationship with computers is also underscored by much of the literature on education. it is also highlighted in professional development and conferences such as  edutech.
