The correct answer to your question is asthma attack:
- The asthma attack is triggered by respiratory tract infections like flu or pneumonia.
- The asthma attack is also triggered by cold due to the decrease in the diameter of bronchi.
- Emotional stress is well known to cause an asthma attack.

Pneumonia is triggered by cold and respiratory tract infections but the emotional stress factor is not being proved yet.

In organisms with large genomes, inversions are more likely to be tolerated if the breakpoints occur in: reciprocal translocatio

andre [41]

Answer:

Non-coding DNA.

Explanation:

Inversion is a type of chromosomal abnormality in which the sequence of a segment of a chromosome is inverted or rotated at an angle of 180 degrees. This type of abnormality can change the reading frame of the gene and can cause mutations.

But if the genome sequence is non-coding that is not involved in the formation of protein synthesis than even if the reading frame is inverted will not affect the phenotype of the cell. Also, the non-coding sequences are removed by the splicing mechanisms.

Thus, Non-coding DNA is correct.

In one type of plant, orange petals (O) are dominant over yellow petals (o) and tall stems (T) are dominant over short stems (t)

Answer No 1:

The set up of the punnet square is shown in the attached diagram. As the alleles assort independently hence the gametes formed will be OT,Ot,OT,Ot and OT,Ot,oT,ot. These will be the outcomes of the possible gametes formed. When these gametes are cross bred, the results are shown in the diagram attached.

Answer No 2:

The outcomes of each possible genotype are:

OOTT = 2/16

OOTt = 4/16

OOtt = 2/16

Oott = 2/16

OoTT = 2/16

OoTt = 4/16

Answer No 3:

The likelihood of each possible offspring phenotype is:

Orange petals with tall stem and orange petals with small stems present in ratio 12:4 i.e. 3:1.
