There are 3 possible genotypes: NN, MN, or MM. In a group of 500 people, the frequency of genotype NN is 40%. How many individua

Readme [11.4K]

235 are the Individual numbers that would expect to have the MN type of genotype.

There are two equations necessary according to Hardy-Weinberg Equilibrium:-

<em>p</em> + q = 1

p² + 2pq + q² = 1

Let,

NN= p

NM=2pq

MM=q

So, according to the question, the frequency of genotype NN is 40%

40% of 500 = $\frac{500*40}{100} = 200$ Numbers of individuals

Frequency of individuals <em>p </em>= $\frac{Numbers of individuals}{Total populations}$ = $\frac{200}{400} = 0.4$

Find <em>p</em>² by taking the square root of <em>p</em>.

√(<em>p</em>) = √(0.4)

= 0.632

So, <em>pp + qq = 1 </em>

<em>qq</em> = 1 - <em>pp </em>= 1 - 0.63

q = 0.37

The allele frequencies in the population are known, now finding the frequency of heterozygous genotype.

By Multiplying<em> 2 × p ×q </em>to get heterozygous genotype

<em>2pq = 2 × 0.63 × 0.37` = 0.47</em>

<em>2pq = 0.47</em>

<em>So, 2pq × total population = 0.47 × 500 = 235, NM genotype.</em>

Mineral matter and organic matter together make up about 50 percent of soil. What two substances make up the other 50 percent?

ale4655 [162]

The particles that make up soil are categorized into three groups by size: sand, silt, and clay. Sand particles are the largest and clay particles the smallest. Although a soil could be all sand, all clay, or all silt, that's rare. Instead most soils are a combination of the three.

The relative percentages of sand, silt, and clay are what give soil its texture. A loamy texture soil, for example, has nearly equal parts of sand, silt, and clay.

SOIL HAS STRUCTURE

Soil structure is the arrangement of soil particles into small clumps, called "peds". Much like the ingredients in cake batter bind together to form a cake, soil particles (sand, silt, clay, and organic matter) bind together to form peds. Peds have various shapes depending on their “ingredients” and the conditions under which the peds formed: getting wet and drying out, freezing and thawing--even people walking on or farming the soil affects the shapes of peds.

Ped shapes roughly resemble balls, blocks, columns, and plates. Between the peds are spaces, or pores, in which air, water, and organisms move. The sizes of the pores and their shapes vary from soil structure to soil structure.
