If the frequency of one allele in a population is 0.7, then the frequency of the alternate allele is 0.3.
Allele frequency is determined by dividing the number of times the allele of concern is seen in a population by the total number of copies of all the alleles at that specific genetic locus in the population.
In case all the allele occurs at the same frequencies in sperm cell and eggs cell, and gametes bond together accidentally to produce zygotes, then the Possibility that any two alleles will combine to form a particular genotype equals the product of the allele frequencies.

By burning chemicals, also coal has been pollution since way back but since its used for electricity theyuse it anyways
Answer:
This question lacks options, the options are:
A) Saliva converting the starch molecules in crackers into simple sugars
B) Digestive enzymes breaking down proteins into smaller fragments
C) bacteria converting lactose into simple sugars in the intestines
D) teeth grinding an almond into smaller pieces in the mouth
The answer is D
Explanation:
A physical change is a change that occurs to a substance without altering its chemical composition. A physical change involved a change in the substance's shape, texture, color, state etc. but not the chemical content of such substances.
In this question involving the processes that occur in digestion, a typical example of physical change is "teeth grinding an almond into smaller pieces in the mouth" because the teeth only changes the shape and texture of the almond. It does not affect the chemical composition of the almond fruit. This is also called mechanical digestion.
Note that, other options involving digestive enzymes breakdown are chemical changes because the enzymes breakdown the chemical components of each substance.
Autosomal trisomies and monosomies are rare in humans because zygotes with these chromosomal aberrations are rarely viable. Hope this helps! Mark brainly please!
