Answer:

0.4

Explanation:

Narrow sense heritability is a form of heritability (the other one is broad sense) that is used to describe the percentage of trait variance that is caused as a result of additive genetic factors. It is represented as h² = Va / Vp

Where Va = additive genetic variance

Vp = phenotypic variance

In this case, to get the narrow-sense heritability of pumpkin weight in this population

We have the following

mean weight of original pumpkin patch = 10lbs

weight of a group of original pumpkin = 15lbs

the average weight of offspring pumpkin = 12lbs

Hence we have h² = Va / Vp

= (12 - 10) ÷ (15 ÷ 10)

= 0.4

It would better your city. The city would look way nicer and a lot of people would probably enjoy a recycling program. For the reasons of having reused items so the dump won't be as bad and it would give more jobs and be a healthy way of discarding old paper and bottles. It could easily help out your city. The recycling program would be a great idea and I hope it could happen.  


I hope this is what you wanted.....
