Скачать или смотреть Test cross or Back cross to identify the genotype of dominant trait, Inheritance

Test cross, Back cross inheritance, Dominant recessive cross, Monohybrid cross, Cross between heterozygous tall plant and homozygous recessive dwarf/short plant.
How to know the unknown genotype of dominant trait.
Homozygous recessive is crossed with unknown genotype variety.
If the phenotype result is 50% of each variety the unknown is heterozygous
If the phenotype result is 100% only one variety then unknown is homozygous
In a species of pea plant, height is controlled by one gene.
The allele for tall is dominant to the allele for short.
A test cross is done to identify the genotype of a tall pea plant.
The table shows the possible phenotypes of the offspring and a description of the genotypes of the tall parent pea plant.
If a large number of offspring are produced, which rows are possible?
