Mendel demonstrated the dominance of the tall allele by crossing homozygous tall pea plants with homozygous short pea plants, resulting in all tall offspring, showing the tall allele is dominant.
Mendel demonstrou a dominância do alelo para altura cruzando plantas de ervilha homozigóticas altas com plantas homozigóticas baixas, resultando em descendentes exclusivamente altos, indicando que o alelo alto é dominante.
| Front | Mendel investigated the genetics of peas. He did not know about genes but shows that inherited characteristics can be dominant or recessive.
Explain how Mendel used homozygous tall and homozygous short pea plants to show that the tall allele is dominant |
|---|---|
| Back | -Mendel crossed homozygous tall and homozygous short pea plants and produced all tall offspring
-Therfore all the offspring had a heterozygous genotype with one tall and one short allele showing that the tall allele is dominant |
