Answer:

In the F1 generation

RR = 0%

Rr = 50% (or 0.5)

rr = 50% (or 0.5)

Explanation:

A pink flowering plant has the genotype Rr. It is heterozygous for the allele. The alleles for this gene appears to show incomplete dominance, as the heterozygous phenotype is a blend of the two homozygous genotypes.

A white flowering plant has the genotype rr. It is homozyogous for the white allele

A punnet square of the cross is shown.

The resulting punnet square shows that only Rr and rr genotypes are possible, at a ratio of 50:50 (or 1:1). Therefore, the genotype frequency of Rr is 50%, and rr is 50% in the F1 generation. This can also be written as 0.5. It is not possible to get a red plant, as the genotype RR can not come from this cross

Stels [109]

Answer:

The growers have not established an integrated commodity chain

Explanation:

Integration of commodity chain includes merging of different alternative practices of agriculture for the overall growth of the society. It may raising cattle like sheep, lambs, cow or horses, etc. or raising deer, buffalo, emus and elk and also doing various plantation of crops such as wheat, barley, rice, coffee, cotton, etc.

But the farmers have not been able to established the integrated commodity chain because of which the growth potential of the alternative agricultural practices like raising emus or buffalos or growing amaranth grains is limited.

Label the main steps in the cellular respiration model?
Angelina_Jolie [31]

Step 1: Glycolysis. In glycolysis, glucose—a six-carbon sugar—undergoes a series of chemical transformations. In the end, it gets converted into two molecules of pyruvate, a three-carbon organic molecule. In these reactions, ATP is made, and \text{NAD}^+NAD  +  N, A, D, superscript is converted to {NADH}NADHN, A, D, H.

Step 2:Pyruvate oxidation. Each pyruvate from glycolysis goes into the mitochondrial matrix—the innermost compartment of mitochondria. There, it’s converted into a two-carbon molecule bound to Co-enzyme A, known as acetyl CoA. Carbon dioxide is released and NADH is generated.

Step 3:Citric acid cycle. The acetyl CoA made in the last step combines with a four carbon molecule and goes through a cycle or reaction, ultimately regenerating the four carbon starting molecule.
