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> :
<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)
Well considering birds follow humane rules, their selection and environment around them being thriving could effect their songs in a positive way. While a bird with a low selection of environmental stuff around them would effect their songs in a bad way giving off a more down manner.
