Answer:
destructive force breaks down features of earth's surface/ constructive forces build up features of earth's surface
Answer:
100% black
Explanation:
<em>The allele for black is dominant over that of the grey fur.</em>
Let B represents the allele for black color and b for grey color.
Homozozygous black rabbit will have the genotype: BB
Heterozygous black rabbit will have the genotype: Bb
If the two are crossed;
BB x Bb
Offspring: BB, Bb, BB, and Bb = 2BB and 2Bb
2BB = Black fur
2Bb = Black fur (heterozygous)
Both BB and Bb offspring are black phenotypically.
<em>Hence, all the offspring will appear black, a phenotypical ratio of </em><em>100% black.</em>
The Sun's magnetic field goes through a cycle, called the solar cycle. Every 11 years or so, the Sun's magnetic field completely flips. This means that the Sun's north and south poles switch places. Then it takes about another 11 years for the Sun's north and south poles to flip back again.
hope this helps!
Answer:
d. Expressivity refers to the range of expression of a given phenotype.
e. Penetrance refers to the percentage of individuals that expresses the mutant phenotype.
Explanation:
Penetrance is the probability of a gene being expressed. Sometimes, phenotype is not observed even when the dominant allele is present. It is a result of various genetic and environmental factors coming together.This phenomenon is called as incomplete or reduced penetrance. For example: polydactyly trait is produced by a dominant allele but its penetrance is low in general population hence few people show this trait.
Expressivity is the variation in phenotypic expression when an allele is penetrant. Same genetic combination for a trait can have different expressivity in the same population. This phenomenon is also a result of genetic and environmental factors acting together. For example: people who do end up showing polydactyly trait may show it to different degrees. Some might have one extra finger, some might have two. Some might have a stub, some might have a full grown finger.
