You are a botanist looking at the plant color in a new breed of Snapdragon. The two parent plants are Blue and Green and when yo
irakobra [83]

Answer:

Incomplete dominance is the inheritance pattern where the dominant allele did not mask the recessive allele completely and form a mix of both alleles. Here the inheritance is the incomplete inheritance. The ratio of F2 generation is 1:2:1.

Given:

R1R1 = 42

R2R2 = 39

R1R2 = 86

Total R1 alleles = 2*42+86 = 170

Total R2 alleles = 2*39+86 = 164

Total alleles = 334

Frequency of allele R1 = 170/334 = 0.51

Frequency of allele R2 = 164 / 334 = 0.49

Expected number of each phenotype:

Total population = 167

Blue = R1R1 = 0.51 * 0.51 * 167 = 43.44

Green = R2R2 = 0.49 * 0.49 * 167 = 40.10

Cyan = 2*R1*R2 = 2*0.51*0.49*167 = 83.46

Phenotype     Observed(O)    Expected (E)    O-E      (O-E)2     (O-E)2/E

Blue                 42                   43.44               -1.44       2.0736     0.0477

cyan                86                   83.46                 2.54     6.4516     0.0773

green              39                    40.1                    -1.1       1.2100      0.0302

Total              167                     167                                               0.1552

Chi-square value = 0.155

Degrees of freedom = no. of phenotypes – 1

Df = 3-1 = 2

Critical value = 5.99

Chi-square value of 0.155 is less than the critical value of 5.99. So we accept the null hypothesis.

In hemoglobin, the transition from t state to r state (low to high affinity) is triggered by:_________
Elena L [17]

In hemoglobin, the transition from t state to r state (low to high affinity) is triggered by Bisphosphoglycerate (BPG)

  • Bisphosphoglycerate (BPG), also known as 2,3-Disphosphoglycerate (2,3-DPG), aids in the transition of hemoglobin from a high-oxygen-affinity to a low-oxygen-affinity state.
  • 2,3-BPG binds to hemoglobin, causing oxygen to be unloaded. Furthermore, 2,3-BPG reduces hemoglobin's affinity for oxygen. As hemoglobin is unloaded in our tissues, 2,3-BPG binds to it, promoting oxygen unloading.
  • When we increase the concentration of 2,3-BPG in our blood, the oxygen binding curve shifts to the right. This means hemoglobin will have a lower affinity for oxygen and will be able to deliver more oxygen to our body's tissues and cells.
