Answer:

The frequency of the dominant allele is 0.7.

Explanation:

If the population is in Hardy-Weinberg equilibrium, the genotypic frequencies are:

p² = freq (AA)

2pq = freq (Aa)

q² = freq (aa)

where p is the frequency of the dominant A allele and q is the frequency of the recessive q allele.

The dominant phenotype of the trait occurs 91% of the time, so

p² + 2pq = 0.91

And therefore the recessive phenotype appears in 9% of the cases:

q² = 1 - 0.91 = 0.09

The frequency of the recessive q allele is thus:

q = √0.09

q=0.3

And because we only have two alleles, the frequencies of both must add to 1.

p + q = 1

p = 1 - q

p = 1 - 0.3

p = 0.7

fomenos
<h2>Answer with Explanation </h2>

If threads are layered from top to bottom brown green red. Green layer will come into focus first if you are using the microscope properly. Green colour has wavelength of 500-565 nm and frequency of 530-606 THz approximately. Due its properties it will come into focus first if you are using the microscope. If anything is covered by brown, red and green, it will appear only green color first by microscope due to its specific characteristics. The visibility of colors depend on the properties which it has.

STALIN [3.7K]

Answer:

Though huge, the Pacific is getting smaller. It was once much wider when all the continents were joined together in the supercontinent, Pangea. The Pacific ocean basin is getting smaller because the Atlantic Ocean is opening and North America and South America are moving westward.
