A rare genetic disease which is due to a recessive allele (a) and that is lethal when homozygous, occurs within a specific popul
valkas [14]

Answer:

40 individuals

Explanation:

The homozygous recessive percentage is equal to q2.

Recessive genotype frequency, q 2 is 1/1000000  = 0.000001  

therefore, q = \sqrt{q2}  = \sqrt{0.000001 }  = 0.001 =  allele "a" frequency  

and p + q = 1, thus, p = 1 – q = 1 – 0.001 = 0.999  

thus, the frequency of allele a = q = 0.001  and the frequency of allele A = p = 0.999

Carriers are heterozygous and are equal to 2pq.  

So, 2pq = 2  x 0.999 x 0.001 x  20,000 = 39.96 (round of to 40)

Hence, 40 individuals will be expected to carry the recessive allele.

1) Students in a science class created Eco columns to mimic a small ecosystem. Grass seeds were planted in 50 grams of potting s
bazaltina [42]

B) The grass height was the dependent variable.

E) Intermediate numbers of insects had the greatest positive impact on grass growth.

<h3>How insects affect the plant growth?</h3>

The grass height was the dependent variable because it depends on the nitrogenous waste of insects and presence of water. The numbers of insects had the greatest positive impact on grass growth because they provides nutrients to plant in the form of nitrogenous water so we can conclude that option B and E are the correct options.
