What happen to water during hydrolysis?
hammer [34]
<span>In a hydrolysis reaction, water (H2O) is added to a bond and cleaves the bond holding molecules together, breaking polymers into 2 pieces. In total, you take a water molecule and split it among the two parts, H+ and OH-. These ions get added to either side with the higher affinity for the cation (H+) and anion (OH-). </span>

Red-flowering snapdragons are homozygous for allele R1. White-flowering snapdragons are homozygous for allele R2. Heterozygous p
lana [24]

Answer:

a) 1/2 red, 1/2 pink; b) all pink; c) 1/4 red, 1/2 pink, 1/4 white; d) 1/2 white, 1/2 pink

Explanation:

The flower color trait in snapdragons shows incomplete dominance: the heterozygous genotype produces an intermediate phenotype between the two different homozygous genoytpes.

<u>The possible genotypes and phenotypes are:</u>

  • R1R1 : red
  • R1R2: pink
  • R2R2: white

<h3>a. R1R1 X R1R2 </h3>

The R1R1 individual only produces R1 gametes. The R1R2 parent produces 1/2 R1 gametes and 1/2 R2 gametes.

<u>For that reason, the F1 will be:</u>

  • 1/2 R1R1 (red)
  • 1/2 R1R2 (pink)

<h3>b. R1R1 X R2R2 </h3>

The R1R1 individual only produces R1 gametes. The R2R2 parent only produces R2 gametes.

<u>For that reason, the F1 will be</u> :

  • 100% R1R2 (pink)

<h3>c. R1R2 X R1R2 </h3>

Both parents are heterozygous. This is a monohybrid cross, and from Mendel's Laws <u>we expect the following offspring:</u>

  • 1/4 R1R1 (red)
  • 2/4 R1R2 (pink)
  • 1/4 R2R2 (white)
<h3 /><h3>d. R1R2 X R2R2</h3>

The R1R2 parent produces 1/2 R1 gametes and 1/2 R2 gametes. The R2R2 individual only produces R2 gametes.

<u>For that reason, the F1 will be:</u>

  • 1/2 R2R2 (white)
  • 1/2 R1R2 (pink)
