Answer:
<h2>Incomplete dominance</h2>
Explanation:
As given here;
Two pure line of four-o'clock plant, one having red flower and other having white flower, when they are crossed, they produce all pink progeny.
So, lets red as RR and white as rr
Cross between RR and rr
Here all offspring are Rr ( Pink ).
It's the result of incomplete dominance, in complete dominance the offspring is the intermediate of both the parents.
F2 generation:
As cross between Rr and Rr
progeny are: RR, Rr, Rr, rr
RR =red
Rr= pink
rr= white
So, red: pink: white = 25:50:25
An organ is a group of tissues working together to develop a function
Homologous recombination occurs wherever there are long regions of the same or similar nucleotide sequence in two dna molecules.
<h3>What is The role of recombination?</h3>
Long jumps through a broad genotype space are caused by recombination. Recombination can substantially facilitate the investigation of novel phenotypes because different portions of this space include distinct novel phenotypes. However, these big jumps frequently ruin a parental, well-adapted genotype. This is a fundamental issue in understanding the role of recombination in evolutionary innovation.
These details demonstrate that the problem is far less serious than one might anticipate based on data from proteins and regulatory circuits. First, because it exchanges system pieces that are consistent with a given phenotype, recombination has far smaller impacts than mutation. Second, previous recombination exposure of a system can greatly boost the system's recombination robustness. It may result in the preservation of the great majority of recombinants
