Question

In a particular flower, being tall (T) is the dominat gene while being short (t) is the recessive gene

Answer 1

It looks like you're describing a classic example of Mendelian genetics, where traits are inherited based on dominant and recessive alleles. In this case, being tall (T) is the dominant trait, while being short (t) is the recessive trait.

Here are a few key points that might help you understand this concept better:

1. **Genotype and Phenotype**:
- The **genotype** refers to the genetic makeup of an individual (e.g., TT, Tt, or tt).
- The **phenotype** is the observable characteristic (e.g., tall or short).

2. **Homozygous and Heterozygous**:
- An individual with two dominant alleles (TT) is **homozygous dominant**.
- An individual with one dominant and one recessive allele (Tt) is **heterozygous**.
- An individual with two recessive alleles (tt) is **homozygous recessive**.

3. **Punnett Square**:
You can use a Punnett square to predict the genetic outcomes of a cross between two plants. For example:
- If you cross a homozygous tall plant (TT) with a homozygous short plant (tt), all offspring will be Tt (tall).
- If you cross two heterozygous tall plants (Tt x Tt), the possible genotypes of the offspring will be:
- 25% TT (tall)
- 50% Tt (tall)
- 25% tt (short)

4. **F1 and F2 Generations**:
In a breeding experiment, the first generation of offspring (F1) typically shows the dominant phenotype. When these F1 individuals are crossed to produce a second generation (F2), you may observe both phenotypes in a specific ratio, depending on the genotypes involved.
