Q: In a cross between a homozygous tall plant and a homozygous short plant, what will be the height of the F1 generation? (2019)
Solution: The height of the F1 generation will be tall, as tall is the dominant trait.
Steps: 5
Step 1: Understand the terms 'homozygous tall' and 'homozygous short'. Homozygous tall means the plant has two tall genes (TT), and homozygous short means it has two short genes (tt).
Step 2: Identify the dominant and recessive traits. In this case, tall (T) is the dominant trait, and short (t) is the recessive trait.
Step 3: Cross the two plants. When you cross a homozygous tall plant (TT) with a homozygous short plant (tt), the offspring (F1 generation) will inherit one gene from each parent.
Step 4: Determine the genotype of the F1 generation. The F1 generation will have the genotype Tt, which means they have one tall gene and one short gene.
Step 5: Identify the phenotype of the F1 generation. Since tall (T) is dominant over short (t), the F1 generation will display the tall phenotype.
