Answer:
Speciation was allopatric or peripatric, but would depend on the number of individuals that dispersed from the original populations.
Explanation:
The new species can be formed in one of the three ways that are allopatric, peripatric, and parapatric speciation.
The allopatric speciation gives rise to new species due to the geographical barriers present between them and the peripatric speciation occurs when a small population enters into a new habitat.
In the given question, species A is more closely related to species B as to species C. This could be due to the allopatric speciation or peripatric speciation but it would depend on the number of the individuals of the population that dispersed to a different elevation which provided a new niche.
Thus, the selected option is correct.
If a red-flowered plant is crossed with a pink flower plants, the genotype ratio would be 1:1 for RR and Rr, and 1:1 for red and pink flower phenotypes.
<h3>Monohybrid crossing</h3>
Red trait has the genotype RR.
Pink trait has the genotype Rr:
Crossing both:
RR x Rr
RR Rr RR Rr
Thus, only RR (red flower) plants and Rr (pink flower) plants are produced.
Genotype ratio = 1RR : 1Rr
Phenotype ratio = 1 Red flower : 1 Pink flower

#SPJ1
Option a answer is xylem , option b answer is parenchyma and option c answer is mertimatic and option d answer is phloem
its called diploid is a two celled chromosome.
Answer:
C. rr
Explanation:
The dominant genotype will always be denoted by the capital version, or in this case R.
The round pea shape is dominant to the wrinkled pea shape, which means that, in the Punnett Square, the combinations of RR, Rr, rR, will all come out to be round pea shape.
The last box, rr, would be the one that gives the wrinkled phenotype.
In this case, by ratio, wrinkled phenotype show up 25%
by ratio, round phenotype show up 75%.
