Genetics worksheet essay

Fill in the Punnett square below and give the ratios for each question beneath the Punnett Square. What is the genotypic ratio of the offspring in Question 3? Zero homozygous green to Four heterozygous green to Zero homozygous clear.

Your response must be at least 75 words in length. (Type your response in the blank area below; it will expand as needed.) In his experiments on pea plants, Mendel observed that these plants had traits such as seed color, flower color, wrinkled or round, and these traits were expressed as one or the other but not intermediate.

These factors in modern science may be equated to chromosomes and they are the ones that bear the genes and transfer them from parent to offspring as traits. These traits come in one form or another and not intermediate because one trait is dominant over the other which is recessive.

A dominant trait will be expressed in the physical characteristics of the offspring when either both the dominant genes are expressed as a pair in the offspring or when a dominant and the recessive gene make up the pair. The recessive gene will only be visible in the offspring’s physical traits when the recessive pair is present in the offspring.
