Mendel 's inheritable 'factors ' influences

Options

A. both phenotype and genotype
B. Phenotype only
C. genotype only
D. neither phenotype nor genotype

Answer

### Step-by-Step Solution:

1. **Understanding Mendel's Inheritance Laws**:
- Mendel proposed three fundamental laws of inheritance: the Law of Dominance, the Law of Segregation, and the Law of Independent Assortment. Each of these laws describes how traits are inherited from one generation to the next.

2. **Law of Dominance**:
- This law states that in a heterozygous individual (having two different alleles for a trait), the dominant allele will mask the effect of the recessive allele. Thus, the phenotype (observable traits) will reflect the dominant allele.

3. **Law of Segregation**:
- According to this law, during the formation of gametes (sperm and eggs), the two alleles for a trait segregate from each other. This means that each gamete carries only one allele for each trait. When fertilization occurs, the offspring will inherit one allele from each parent.

4. **Law of Independent Assortment**:
- This law states that the alleles for different traits are distributed to gametes independently of one another. This means that the inheritance of one trait will not affect the inheritance of another trait.

5. **Influence of Genotype and Phenotype**:
- The genotype (the genetic makeup) influences the phenotype (the physical expression of traits). Changes in genotype can lead to changes in phenotype, demonstrating that both factors play a crucial role in inheritance.

6. **Conclusion**:
- Therefore, Mendel's inheritable factors influence both the genotype and phenotype, as they are interconnected in determining the traits of an organism.

### Final Answer:
Mendel's inheritable factors influence both phenotype and genotype.
