In a study, competition among plants
are normal. Hence, all plants required a few basic elements like the light,
water, nitrogen, or phosphorus, depending upon the species and the location. Evidence
that can conclude that competition do really happen in plants is that some plants
release toxins into the soil, in their dropped leaves which wipe out the competition
for soil nutrients (such as weeds). And when it come an area with many trees in
close proximity such as a forest, height is also indicative of competition for
light.
Answer:
Genetic variation that alter gene activity or protein function can introduce different traits in an organism. If trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection).
Answer:
3:1
Explanation:
To find out the phenotypic ratio, we need to do a Punnet Square.
We know that R and I are the dominant alleles that produce red flowers, and r and i are the recessive traits.
<u> ║R ║ r</u>
<u>I ║RI║Ir</u>
<u>i ║Ri║ir</u>
The genotype ratio would be 3 because the dominant traits are present three times (RI, Ir, and Ri) and 1 for the recessive trait since it only appears once in the Punnet Square (ir). In conclusion, the phenotypic ratio form the roses are 3:1
