Those are DNA sequences. Each sequence of three bases in a DNA strand is called a codon. Each codon codes for a particular amino acid. So for example the codon AGC stands for the amino acids serine. The codon TGG stands for the amino acids threonine. The codon CTG stands for aspartic acid. So, the DNA sequence AGCTGGCTG codes for the amino acid sequence serine-threonine-aspartic acid. I hope the helps! :)

In tomatoes, a heterozygous plant with normal fruit and purple stems is crossed with a recessive plant having fasciated fruit an
Pani-rosa [81]

Answer:

Recombination frequency, P = 0.23.

If the recombination frequency is < 50%, genes are linked. A RF of 23% tells us that these two genes are in the same chromosome, close enough to be linked.

  • 1% of recombinations = 1 map unit
  • 23% = 23 map units

The genes for stem color and fruit type seem to be in the same chromosome, linked and 23 MP apart.

Explanation:        

In the present example, the genes for stem color and fruit type seem to be linked.

To know if two genes are linked, we must observe the progeny distribution. If individuals, whos genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1. If we observe a different distribution, that is that phenotypes appear in different proportions, we can assume that genes are linked in the double heterozygote parent.  

In this way, we might verify which are the recombinant gametes produced by the di-hybrid, and we will be able to recognize them by looking at the phenotypes with <u>lower frequencies in the progeny</u><u>.</u>    

The following distribution of offspring is observed:

  • normal fruit, purple stems 38.5%
  • fasciated fruit green stems 38.5%
  • normal fruit, green stems 11.5%
  • fasciated fruit, purple stems 11.5%

38.5% + 38.5% + 11.5% + 11.5% = 100%

N (total number of individuals in the progeny) = 100

  • number of individuals with normal fruit, purple stems 38.5
  • number of individuals with fasciated fruit green stems 38.5
  • number of individuals with normal fruit, green stems 11.5
  • number of individuals with fasciated fruit, purple stems 11.5

To calculate the recombination frequency we will make use of the next formula: P = Recombinant number / Total of individuals. The genetic distance will result from multiplying that frequency by 100 and expressing it in map units (MU).

P = Recombinant number / Total of individuals.

P = 11.5 + 11.5 / 100

P = 0.23  

We need to know that 1% of recombinations = 1 map unit = 1cm. Also, the maximum recombination frequency is always 50%.  This means that if the recombination frequency is < 50%, genes are linked. A RF of 23% tells us that these two genes are in the same chromosome, close enough to be linked. FR 23% = 23 UM.

Komok [63]

The mentioned case represents secondary succession.  

Secondary succession is one of the two kinds of ecological succession of plant life. Secondary succession refers to a procedure initiated by an incident, like harvesting, forest fire, hurricane, and others, which minimizes an already settled ecosystem to a lesser population of species.  

Thus, it can be said that the secondary succession takes place in preexisting soil on the other hand primary succession takes place in a place devoid of soil.  

Secondary succession is the ecological succession, which takes place after the initial succession has been disrupted and certain plant and animal species do prevail. It is usually faster in comparison to primary succession.
