Answer:

Explanation:

quadrant to determine the population of plants. The quadrants is square in shape and its been marked with boundaries. It is place on a particular location to determine the number of plants.

Population of owl in 2000 =200 owl

Population of owl in 2004 =126 owl

Change in population = 200 -126=74 plants

There is a decrease by 74 in the number of plant.

prisoha [69]

To calculate the frequency of the heterozygote genotype (Pq) for this gene we must use the Hardy-Weinberg equation ( p2 + 2pq + q2 = 1 ). This equation relies on the Hardy-Weinberg principle, a model in population genetics that states that the frequency of the alleles in a population is never changing, only the combinations (the genotypes) are changing.

If there are only two alleles (variations) of this gene in a population, then their frequencies should add up to 1 (100%). From this, we can calculate the frequency of the q allele.

p +q=1

0,3 +q=1

q= 1-0,3

q= 0,7

Now hat we have the frequency of the q allele we can use the HW equation to calculate the frequency of the heterozygotes.

p^{2} + 2pq + q^{2} = 1

(0,3)^{2} + 2pq +(0.7)^{2} = 1

0,09 + 2pq +0.49= 1

2pq +0,58= 1

2pq= 1-0.58

2pq=0,42

The freqency of the heterozygotes in this population is 0.42

The F2 generation phenotypes resulting from the monohybrid cross of purebreds display a ratio of _____.
ki77a [65]
In the sentence "The F2 generation phenotypes resulting from the monohybrid cross of purebreds display a ratio of _____" the word that correctly completes the sentence is 3:1. In the monohybrid cross of purebreds, F1 generation will consist of heterozygotes with dominant phenotype. When F1 generation cross, the F2 generation phenotypes will be as following: 3 dominant phenotypes (1 dominant homozygote and 2 heterozygotes) and 1 recessive phenotype (1 recessive homozygote).
