When Mendel crossed together two contrasting homozygous individuals, the phenotype of the hybrid in the F1 cross appeared to be that of:
- A
Recessive parent
- B
Dominant parent
- C
Indifferent
- D
Half dominant & recessive
Dominant parent is correct.
When Mendel crossed two contrasting homozygous individuals, all the offsprings of G1 generation were of dominant phenotype.
For example, crossed between round and wrinkled seeded plants produced plants with round seeds in F1 generation.STB- Pg 184.
Recessive parent – The phenotype of the hybrid in the F1 generation would not be that of the recessive parent when crossing contrasting homozygous individuals.
Dominant parent is correct.
When Mendel crossed two contrasting homozygous individuals, all the offspring of the G1 generation were of the dominant phenotype.
For example, crosses between round and wrinkled seeded plants produced plants with round seeds in the F1 generation. STB-—Pg. 184.
Indifferent – The F1 generation would show a clear dominant or recessive trait, not an indifferent phenotype.
- Half dominant & recessive – The F1 generation would not show a combination of both traits; it would show the dominant phenotype.
