Understanding Plant Genetics in Tomato Plants

When considering the genetic traits of tomato plants, it's important to understand the principles of dominance and recessiveness in genetics. In this case, the normal plant height (A) and red fruit color (B) are dominant traits, while dwarfism and yellow fruit color are recessive traits.

When crossing plants with the genotypes AAVV and AAVv, we can determine the potential outcomes based on Mendelian genetics.

Genotypes and Phenotypes: - The genotype AAVV represents a plant with normal height and red fruit color, while AAVv represents a plant with normal height and red fruit color but carrying the recessive allele for yellow fruit color.

Possible Offspring: - When crossing these two genotypes, the Punnett square can be used to determine the potential genotypes and phenotypes of the offspring.

Punnett Square: ``` | A | A | V | V | ------------------- A | A | A | V | V | A | A | A | V | V | V | V | V | V | V | V | V | V | V | V | ```

Outcome: - All the offspring from this cross will have the genotype AAVV, resulting in plants with normal height and red fruit color.

In conclusion, the plants obtained from crossing the genotypes AAVV and AAVv will all have normal height and red fruit color, as both of these traits are dominant.
