Correct option is A
The Correct Answer Is: (A) Tall
Explanation:
According to Mendel's experiments on pea plants, when he crossed tall pea plants (T) with short pea plants (t), all the F1 progeny in the first generation were tall.
According to Mendel's experiments on pea plants, when he crossed tall pea plants (T) with short pea plants (t), all the F1 progeny in the first generation were tall.
This result showed that the tall trait is dominant over the short (dwarf) trait. Mendel concluded that each pea plant has two alleles for a trait, one inherited from each parent, and the dominant allele (T) expressed itself in the F1 generation.
Information Booster:
- Mendel used the terms dominant and recessive to describe the traits he observed.
- The tall allele (T) is dominant, while the short allele (t) is recessive.
- When crossing homozygous tall (TT) with homozygous short (tt) plants, the F1 progeny inherit one allele from each parent, resulting in the genotype Tt (heterozygous).
- In the F1 generation, only the dominant trait (tall) appears, even though the recessive allele (short) is present in the genotype.
- Mendel’s findings led to the formulation of the principles of inheritance, such as the Law of Dominance.
- The Law of Segregation states that alleles separate during gamete formation, ensuring that each offspring inherits one allele from each parent.
Additional Information:
- Short: it is recessive and was masked by the dominant tall allele.
- Dwarf: "Dwarf" is an alternate term sometimes used to describe short traits.
- Medium: Medium height does not appear in Mendel’s experiments with pea plants, as the traits follow a dominant-recessive inheritance pattern.
