In a population of pea plants, 36 plants are homozygous for the dominant trait of yellow peas (yy), 48 plants are heterozygous for the yellow pea trait (yy), and 16 plants have green peas (yy). what is the frequency of the dominant allele (y) in the population? a. 0.40 b. 0.55 c. 0.60 d. 0.75

The correct answer would be C. 0.60

It can be calculated with the help of Hardy-Weinberg equation i.e

p² + q² + 2pq = 1

Also, p + q = 1

Number of homozygous dominant (YY) = 36

Number of homozygous recessive (yy) = 16

Number of heterozygous dominant (Yy) = 48

Total number of plants = 100

Now, frequency of homozygous dominant (YY) = 36/100 = 0.36

Therefore, p² = 0.36

So, p = √0.36 = 0.60

Hence, frequency of dominant allele (Y) = 0.60

answer: c. two haploid cells

explanation:

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
