The recessive allele frequency for the population.
150 pigs have 300 alleles total
There exists 180 alleles for the recessive trait blue eyes.
Assign 'q' to the frequency of blue eye alleles
q = 180/300 = 0.6 Answer
Answer: yersinia pestis spreads from a bubo or from the lungs into the bloodstream. It can also happen if the Y. pestis bacteria get into the bloodstream after a person has direct contact with the meat or blood of an infected animal.
Explanation:
Answer:
a. Developing cells may express different parts of their identical genetic instructions.
Explanation:
Humans are multicellular organisms i.e. we possess many cells in our body. These cells increase as a result of division. Although all of the cells of humans develop from one fertilized egg (zygote), the human is born with many different types of cells because of a process called CELL DIFFERENTIATION.
Cell differentiation is a process in multicellular organisms where a cell becomes more specialized in function as it divides. The set of genes contained in each cell are not expressed simultaneously i.e. some genes are expressed while others are repressed. This is how cells with the same gene possess different functions. Therefore, according to this question, developing cells may express different parts of their identical genetic instructions to be of different types.
Divergent boundaries in the middle of the ocean contribute to seafloor spreading. As plates made of oceanic crust pull apart, a crack in the ocean floor appears. Magma then oozes up from the mantle to fill in the space between the plates, forming a raised ridge called a mid-ocean ridge.
