In pea plants, yellow seeds are dominant to green. If a heterozygous y...
Yellow seeds in pea plants are dominant over green seeds. This means that if a pea plant has one allele for yellow seeds (Y) and one allele for green seeds (y), it will have yellow seeds because the yellow allele is dominant. On the other hand, for a pea plant to have green seeds, it must have two alleles for green seeds (yy).
When a heterozygous yellow seeded plant (Yy) is crossed with a green seeded plant (yy), we can use Punnett square analysis to determine the expected ratio of yellow and green seeded plants in the F1 generation.
Punnett Square Analysis:
- The parent plant with yellow seeds is heterozygous (Yy), so we represent its alleles as Y and y.
- The parent plant with green seeds is homozygous recessive (yy), so we represent its alleles as y and y.
The Punnett square for this cross would look like this:
Y y
---------------
y | Yy | yy |
---------------
From this Punnett square, we can see that there are two possible genotypes for the F1 generation: Yy and yy. However, since the yellow allele is dominant, both Yy and yy genotypes will have yellow seeds. Therefore, all the plants in the F1 generation will have yellow seeds.
Expected Ratio:
Since all the plants in the F1 generation will have yellow seeds, the ratio of yellow to green seeded plants in the F1 generation is 100% yellow (YY or Yy) and 0% green (yy). This can also be expressed as a ratio of 1:0 or simply 1.
Therefore, the correct answer is option D) 50:50.
