The answer is 0.42.
According to the Hardy-Weinberg equilibrium:
p + q = 1
p² + 2pq + q² = 1
where p is a frequency of a1 allele, q is a frequency of a2 allele, p² is a frequency of a1a1 genotype, 2pq is a frequency of a1a2 genotype, q² is a frequency of a2a2 genotype.
If <span>70% of the gametes produced in the population contain the a1 allele, then:
p = 70% = 0.7.
If p = 0.7 and p + q = 1, then q = 1 - p = 1 - 0.7 = 0.3
So, the proportion of </span>the flies that carry both a1 and a2 (a1a2 genotype) is:
2pq = 2 * 0.7 * 0.3 = 0.42
Answer:
It is important to understand the difference between rotations and revolutions. When an object turns around an internal axis (like the Earth turns around its axis) it is called a rotation. When an object circles an external axis (like the Earth circles the sun) it is called a revolution.

Answer: The correct answer is- to see what new traits might appear next.
As per the information in the question, pigeon breeder selects the offspring of pigeons with spotted bodies.
Spotted body is a trait that would be depicted by two different alleles ( such as one for black and other for white color).
As both the alleles for the color are represented in the pigeon offspring, therefore, it is a case of co-dominance ( let us take its genotype as Bb, where 'B' is allele for black and 'b' for white color).
When pigeons with spotted bodies are cross bred, they can produce pigeon with spotted and non spotted ( such as black 'BB', white 'bb', or spotted 'Bb' ) body depending upon the allele that is passed to the offspring.
Thus, pigeon breeder selects the spotted bodies pigeons and then breed those offspring to see what new traits might appear next.
