Today class we will be learning about Mendel's second experiment.
I already know that a dominant homozygous parent will beat out a recessive homozygous parent any time, but what would the heterozygous parents do?
Ooo, I know!
You see John, Mendel crossed true-breeding plants. Both plants were homozygous. One plant made yellow and round peas and the other made wrinkled green peas.
The first group of offspring aka F1 the peas were all yellow and round. This how he found out that yellow and round peas are donminant and green and wrinkled peas are resessive
That is right. He also found out that the genotype in each F1 plant is RyYy. F1 plants were all heterozyous for both shape and color. The next group of offspring aka F2 produced 556 seeds. 315 were round and yellow, 32 were wrinkled and green, and 209 had a combination of phenotype therefore combination of alleles that were not found in either parents
