For a gene suspected of causing hypertension in humans, you observe the following genotype frequencies: a1a1 0.574; a1a2 0.339; a2a2 0.087. is this gene in hardy-weinberg equilibrium? why or why not? (assume that a difference of three percent or more in any of the observed versus expected frequencies is statistically significant.) see section 23.1 (page 458) .

This gene is in Hardy-Weinberg equilibrium

Explanation:

As per the second equation of Hardy-Weinberg equilibrium, sum of genotypic frequencies of all types with in a population must be equal to one

Frequency for genotype A1A1 ()

Frequency for genotype A2A2 ()

Frequency for genotype A2A1 ()

Now,

Substituting the given values in above equation, we get -

Hence, this gene is in Hardy-Weinberg equilibrium

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
