In an experiment, homozygous dominant plants with purple flowers were crossed with homozygous recessive plants with white flowers. Mendel collected the seeds from this cross, grew F1-generation plants, crossed them to form a second generation, and then analyzed the plants of the resulting F2 generation. What results did he probably get?
|
1/2 the F1 and 3/4 of the F2 generation flowers were white |
||
|
1/2 the F1 and 1/4 of the F2 generation flowers were purple |
||
|
3/4 of the F1 and 9/16 of the F2 generation flowers were purple |
||
|
All of the F1 and F2 generation flowers were purple. |
||
|
All of the F1 and 3/4 of the F2 generation flowers were purple |

In a given species of plant, some have purple flowers and others have white flowers. A homozygous purple variety is crossed with a homozygous white variety. All of the F1 have purple flowers. When the F1 are allowed to self-fertilize the F2 appear in a ratio of 9/16 purple and 7/16 white. What does this ratio tell us?

In the pea plants that Mendel studiod, purple/violet lowers are dominant to white flowers and yellow poas are dominant to green peas. The alleles designated for each phenotype are W for purple/hiolet flowers, w for white flowers, G lor yellow peas, and g for green peas. 1) You are provided two plants with the genotypes GgWw and g9ww. Indicate their corresponding phenotype. (1 point). 2) Now you must cross these plants together to yield an F1 generation. Write out the...
