The correct answer is insertion!
a G was added in the third sequence!
hope this helps!!
        
             
        
        
        
Answer:
Genetic information is passed from generation to generation through inherited units of chemical information (in most cases, genes). Organisms produce other similar organisms through sexual reproduction, which allows the line of genetic material to be maintained and generations to be linked

Answer:
The ratio of blue to white offspring in the progeny is 4 blue : 12 white. 
Explanation:
<u>Available data:</u>
- The dominant allele K is necessary to synthesize blue flower pigment 
- K is inhibited by the dominant allele D 
- Plants with the genotype K- D- will not produce pigment (and their flowers will be white) 
 Cross: testcross for (Kk Dd) plants 
Parental)   KkDd     x     kkdd
Gametes) KD   kD   Kd   kd      
                  kd   kd   kd   kd
Punnet square)        KD        Kd       kD       kd
                       kd     KkDd   Kkdd   kkDd   kkdd
                       kd     KkDd   Kkdd   kkDd   kkdd
                       kd     KkDd   Kkdd   kkDd   kkdd
                       kd     KkDd   Kkdd   kkDd   kkdd
- Whenever D is present, it inhibits the expression of the K gene, so every plant with the dominant D allele will be white. This plants´ genotype is kkD- or K-D-.
- Whenever D is absent and K is present, every plant with genotype K-dd will be blue.
- The recessive form for K and D genes will express white-flowered plants, with genotype ddkk
F1) Progeny genotype: 4/16 KkDd, white-flowered plants
                                       4/16 Kkdd, blue-flowered plants
                                       4/16 kkDd, white-flowered plants
                                       4/16 kkdd, white-flowered plants
      The ratio of blue to white offspring in the progeny is 4 blue : 12 white. 
      Blue-flowered plants: 4 Kkdd
      White-flowered plants: 4 KkDd + 4 kkDd + 4 kkdd
 
        
             
        
        
        
Answer:
Sister chromatids are identical copies derived from the replication of a parental chromosome. They remain attached to each other at the centromere. They are genetically identical, barring rare mutations and crossing over with homologous chromosomes.
