Answer:true example of environmental policy is on banning the use of plastic bags which initiate waste management as it initiate re-using
To solve this problem we first need to find the amount of gametes a fruit fly produces in a meiotic division. For this we will use the formula 
, where n represents the number of gene pairs. In our case then, 
= 2.2.2.2 = 16
So a fly produces 16 different combinations of gametes. If this fly crosses another one, we have a universe of possibilities of combinations given by the multiplication of the male and female gametes. In the case, then, it would be 16 x 16.
16 x 16 = 256
The genotype of a heterozygous individual is Aa, of a homozygous dominant is AA, and of a homozygous recessive individual is aa.
<h3>What is a dominant genotype?</h3>
A dominant genotype is a set of gene variants characterized to have dominant alleles that mask the expression of recessive alleles in heterozygous individuals in cases of complete dominance.
In conclusion, the genotype of a heterozygous individual is Aa, of a homozygous dominant is AA, and of a homozygous recessive individual is aa.

Answer is B. Pioneer communities contain few species, while climax communities have many species.
Pioneer species are the first species that start life in an area. Their growth is fast and soon replaced by next community. Whereas, climax communities are made of many species. They are stable is not replaced by any other community. They are supporting new life.
