Childhood Obesity: A New Epidemic The nature of society has changed greatly since the mid 20th century. With this change‚ the face and size of American youth has been altered. Increasing numbers of children ranging from infants to adolescents have become obese. Since the 1970’s‚ obesity in children age two to five and adolescents age 12 to 19 has more than doubled. However‚ the fact that the percentage of children between the ages of 6 and 11 who are obese has tripled is increasingly frightening

generation to determine their mode of inheritance; whether they are sex-linked or autosomal‚ and recessive or dominant‚ utilizing the Chi-square statistical test‚ which compares observed and predicted results‚ and to ultimately determine the genotype and phenotype of the parents. In this experiment‚ given the nature of a dihybrid cross‚ the following hypothesis was formulated. According to Mendel’s Laws of Inheritance‚ the F2 generation of a dihybrid cross involving two traits of a homozygous recessive

Mendelian Genetics * Pea plants have several advantages for genetics. * Pea plants are available in many varieties with distinct heritable features (characters) with different variants (traits). * Another advantage of peas is that Mendel had strict control over which plants mated with which. * Each pea plant has male (stamens) and female (carpal) sexual organs. * In nature‚ pea plants typically self-fertilize‚ fertilizing ova with their own sperm.

“Human genetic engineering is the alteration of an individual’s genotype with the aim of choosing the phenotype of a newborn or changing the existing phenotype of a child or adult. It holds the promise of curing genetic diseases like cystic fibrosis‚ and increasing the immunity of people to viruses. It is speculated that genetic engineering could be used to change physical appearance‚ metabolism‚ and even improve mental faculties like memory and intelligence”.

candidate genes‚ various forward or reverse genetic tools may be implemented to find candidate genes. Forward genetics implies that the phenotype or function is known and can be used to figure out which gene causes the specific phenotype or function. Reverse genetics starts from genes that have been identified from sequencing projects‚ but the function or phenotype is not yet known. Many genomic techniques are used in forward and reverse genetics. However‚ the ones I will be addressing in this paper
