Answer: 1. Gregor Mendell 2. Genetics 3. Phenotype 4. Homozygous 5. Predict
Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Genetics is the scientific study of genes and the heredity of how certain qualities or traits are passed from parents to offspring as a result of changes in DNA sequence.A phenotype refers to the observable physical properties of an organism; these include the organism's appearance, development, and behavior. An organism's phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.If the two alleles are the same, the individual is homozygous for that allele.A Punnett Square is a helpful tool that helps to predict the variations and probabilities that can come from cross-breeding.
