If it's a microscope it should be on the low power setting (10x) and you should only use the course adjustment knob which is the bigger one.
Answer:
1. genetics
2. constant
3. genetic drift
4. Modern synthesis combines the ideas surrounding evolution and natural selection with those of genetics.
5. A genotype is the genetic makeup of an organism. It describes the DNA that underlies a trait. There are dominant and recessive alleles and heterozygous and homozygous genotypes. A phenotype is the physical manifestation of that genotype.
6. The most common type of mutation is a deleterious mutation. Natural selection acts to remove this allele from the population.
7. The most common type of observed mutation is a neutral mutation. This mutation doesn't impact natural selection in any noticeable way since it doesn't impact the fit of that organism. Since neutral mutations convey no advantage, they generally must spread in a population through drift. Many also will disappear through drift.
8. During sexual reproduction, each organism is provided a copy of chromosomes from each parent, and this allows for new combinations of DNA.
9. This isn't an example of genetic drift because there's a genetic component to the ability to withstand severe temperatures. Therefore, this is an example of natural selection, related to surviving extreme environmental conditions
Explanation:
Answer:
b. a segment of a DNA molecule.
The picture is what the punnet square looks like. Capital S represents short hair and lowercase s represents long hair.
The genotypic ratio is 2:2 (Ss 50% and ss 50%)
The phenotypic ratio is 2:2 (short hair 50% and long hair 50%)
