Answer:
0.25%
Explanation:
20 people start the new population. So there are 20 genes or 40 alleles for the recessive disorder phenylketonuria. 2 out of 40 alleles are recessive for the condition hence frequency of the allele = 2/40 = 0.05
Frequency of the allele does not change when the population increases so it is in Hardy-Weinberg equilibrium. According to it, if q is the frequency of recessive allele, q² = frequency of the recessive condition
Here, q = 0.05 So,
q² = (0.05)² = 0.0025
In percentage, it is 100 * 0.0025 = 0.25% 
Hence, incidence of phenylketonuria in the new population is 0.25%

Answer:Texas cichlid (Herichthys cyanoguttatus)
Explanation:
Texas cichlid (Herichthys cyanoguttatus, ex. Cichlasoma cyanoguttatum) is a large, good looking and at that rather aggressive cichlid fish. In the wild it inhabits in rivers of Texas (for example, Rio Grande, due to which the fish got its name Rio Grande cichlid) and in North Mexico.
