A population has a gene locus with two alleles, A1 and A2. Tests show that 30% of the gametes produced in the population contain the A1 allele. If the population is in Hardy-Weinberg equilibrium, what proportion of the flies carry both A1 and A2?

The question is incomplete as it does not have the options which are:

0.7 0.09 0.21 0.42 0.49

0.42

Explanation:

Hardy Weinberg equilibrium states that a population doe not evolve if no evolutionary force act on the population as the population remains in equilibrium.

The principles considered dominant allele as P and recessive allele as q. The sum of allele frequency will be p+q = 1 and the genotypic frequency will be P²+2Pq+q²=1.

2pq represents the population which is heterozygous that is having both the alleles.

In the given question, since the allele frequency of A1 is 30% or O.30, Therefore using p+q=1,   the frequency of A2 allele will be 1-p= 0.70.

Now 2pq will be 2x (0.30 x 0.70)

= 2x .210

=. 420

Thus, 0.42 is the correct answer.

Characteristic expected of mineral from lava at earth's surface

phaneritic textures in which phaner means visible so phaneritic textures are standard of impertinent volcanic rocks. these rocks crystallized gradually under the surface of earth. when the magma cools deliberately then the ores have chance to develop and produce long crystals.

In fact it is not just nuclear fusion and fission that  can  transform  matter  (or mass)into energy. any time  energy  is produced, some small amount of  matter  or mass isconverted into energy.
