Since after crossing a red and a white flower produced pink flowers, the red color trait shows an incomplete dominance and has a genotype of Rr.
Using the Punnett to determine the cross between pink and white flowers:
| R | r |
r | Rr | rr |
r | Rr | rr |
The results indicate that the cross between pink and white flowers will produce a ratio of 1:1
Rr x rr
All of the above, select all
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)
Answer:
B. true, because immunity is nonexcludable, and everyone can simultaneously enjoy the "herd immunity."
Explanation:
When a lot of people get vaccinated against a disease, the chances of spreading of that disease drastically decreases in the population. Even if someone is not vaccinated against that disease, their chances of contracting it are low because other people are vaccinated and hence its incidence rate in population is low. This phenomena is called as herd immunity. For example: 19 out of 20 people should be vaccinated against measles to protect the non vaccinated ones.
Herd immunity benefits the entire public and is considered a classic public good. It is nonexcludable which means that someone can not be excluded from being benefited by it. Two people residing in the same population will reap the benefits of herd immunity even if the degree of benefit might be different.
