To describe: A genetic explanation for the inheritance pattern of a sickly yellowish trait.
Introduction: According to Mendel's first law of dominance, each gene has two alleles that code for a specific trait. Among these two alleles, one is always dominant, which means that it will always show, while the other allele is recessive meaning its presence can be masked by the dominant allele.
To suggest: A simple test for the inheritance pattern of a sickly yellowish trait.
Introduction: The cross between individuals possessing two pairs of contrasting traits (four alleles) is known as a dihybrid cross. It involves a cross between two true-breeding or pure parents.
To explain: The relationship between chloroplasts and the reduced photosynthesis, sickliness, and yellowish appearance of a plant.
Introduction: The plant organelle chloroplast allows the plant to perform photosynthesis or to make its own food or energy.
