Explanation:
Mendel's experiment involved crossing a pure white flowered recessive pea plant with a dominant pure red flowered plant. Based on the principles of inheritance, the first generation of hybrids from this cross should show all red flowered plants.
Principles of Inheritance:
1. Dominant and Recessive Traits: In genetics, traits can be either dominant or recessive. Dominant traits are expressed when an individual has at least one copy of the dominant allele, while recessive traits are only expressed when an individual has two copies of the recessive allele.
2. Law of Segregation: According to Mendel's law of segregation, during the formation of gametes, the alleles for each gene segregate from each other so that each gamete carries only one allele for each gene.
3. Homozygous and Heterozygous: Homozygous individuals carry two copies of the same allele (e.g., RR for red flowers or rr for white flowers), while heterozygous individuals carry one copy of each allele (e.g., Rr).
Mendel's Experiment:
Mendel crossed a pure white flowered recessive plant (rr) with a dominant pure red flowered plant (RR). The dominant allele (R) for red flowers would mask the expression of the recessive allele (r) for white flowers.
The genotype of the F1 generation would be Rr, with the dominant allele (R) from the red flowered parent and the recessive allele (r) from the white flowered parent.
Phenotype of the F1 Generation:
Since the dominant allele (R) masks the expression of the recessive allele (r), all the plants in the F1 generation would have red flowers. This is because the red flower trait is dominant over the white flower trait.
Therefore, the correct answer is option 'B' - all red flowered plants.
