Answer:
p represents the frequency of the dominant allele (in decimal form) of a gene
q represents the frequency of the recessive allele (in decimal form) of a gene
These 2 alleles are different; one is dominant, one is recessive.
p^2 = the frequency of homozygous dominant individuals in the population (decimal form)
2pq = the frequency of heterozygous individuals in the population (decimal form)
q^2 = the frequency of homozygous recessive in the population (decimal form)
Giemsa stain shows the staining of centromeres.
- C-banding, which involves denaturing the chromosomes in a saturated alkaline solution followed by Giemsa staining, is a technique specifically used to identify heterochromatin.
- Different banding methods can be selected when identifying chromosomes. Chromosome banding is an important technique used in chromosome karyotyping to distinguish between normal and defective chromosomes for clinical and scientific purposes.
- The most common dye-based chromosome banding methods are Giemsa (G), reverse (R), and centromere (C). G-banding stains trypsinized chromosomes, whereas R-banding uses hot acidic saline to denature the chromosomes prior to Giemsa staining.
- It contains a significant amount of AT-rich satellite DNA. Just as G-banding represents AT-rich sections of chromosomes, so does Q-banding.
Therefore, centromeres is the correct answer.

<u>Answer:</u>
All cells have same genes, but different genes are active in different cells
<u>Explanation:</u>
Most living organisms are made up of different kinds of cells specialize in performing various functions like nerve cells perform different functions than blood cells. But all the cells are composed of same set of genetic information.
Since biochemical function is found out mainly by some specific enzymes, different sets of genes must be turned on and off in the various cell types to perform different functions. This is how cells differentiate for different functional capabilities.
True because of the fact that index fossils help correlate and date from its origin and date of existence. basically, it is a fossil that is kept and annalized.
