Answer:
The male reproduction system.
Answer:
Parentals: PP (purple) and pp (white)
F1: Pp (purple)
Explanation:
When the two parental plants of differing phenotypes (purple or white flowers) cross, the F1 is 100% purple. This result suggests that the parentals were true breeding (homozygous), with purple flowers being the dominant allele.
When the F1 self pollinates, the F2 shows proportions very similar to 3/4 purple and 1/4 white (401/532 ≅ 3/4 and 131/532 ≅ 1/4). The 3:1 phenotypic ratio is typical of the offspring resulting from a cross between two heterozygous individuals.
The results make sense if the genotypes of the different generations are:
Parentals: PP (purple) X pp (white)
F1: Pp (purple)
F2: 1/4 PP, 2/4 Pp, 1/4 pp
Among reported cases through May 17, 90% were unvaccinated or their vaccination status was unknown. Fifty-five (6%) cases were acquired outside of the U.S. (international importations) and 825 (94%) were acquired in the U.S. Most cases (94%) were related to outbreaks and 75% were related to outbreaks in New York City and New York State.
Answer:
Erosion is the natural process by which soil / rock are removed from the Earth's surface by exogenetic processes such as wind or water flow, transported and deposited in other locations. Leaching is the removal of soluble material from soil or other material by percolating water.
The permeability of the postsynaptic neuron changes; consequently, its membrane potential is changed as well
