In pea plants, purple flower color, C, is dominant to white flower color, c. The table shows the frequencies of the dominant and recessive alleles in three generations of peas in a garden. Generation 1 has 200 flowers, generation 2 has 400, generation 3 has 400. Allele Frequency for Flower Color in Peas Generation p q 1 0.5 0.5 2 0.6 0.4 3 0.7 0.3 Which best describes the number of flowers? Generation 1 has more white flowers than generation 2. Generation 3 has more white flowers than generation 2. Generation 2 has fewer purple flowers than generation 1. Generation 1 has fewer purple flowers than generation 3.

Respuesta :

The correct answer is option D

Generation 1 has fewer purple flowers than generation as the allele frequency of purple flower in generation 1 is 0.5 while the allele frequency for white flower in generation 3 is 0.3


Answer:

Option D, Generation 1 has fewer purple flowers than generation 3 is correct.

Explanation:

Given -

Ration of color flower to white flower in generation I [tex]= 0.5:0.5[/tex]

Total Number of color flowers in generation I

[tex]= 0.5 * 200\\= 100[/tex]

Total Number of white flowers in generation I

[tex]= 0.5 * 200\\= 100[/tex]

Ration of color flower to white flower in generation II [tex]= 0.6:0.4[/tex]

Total Number of color flowers in generation II

[tex]= 0.6 * 400\\= 240[/tex]

Total Number of white flowers in generation II

[tex]= 0.4 * 400\\= 160[/tex]

Ration of color flower to white flower in generation III [tex]= 0.7:0.3[/tex]

Total Number of color flowers in generation III

[tex]= 0.7 * 400\\= 280[/tex]

Total Number of white flowers in generation III

[tex]= 0.3 * 400\\= 120[/tex]

Option D, Generation 1 has fewer purple flowers than generation 3 is correct.
