Mendel’s approach to answering scientific questions was highly focused. He chose just a handful of traits to study‚ seven to be exact‚ and by doing so was able to more easily keep an accurate mathematical record of each of the traits and how they carried to subsequent generations. The approach that he took‚ looking at a lesser quantity of traits‚ gave him an advantage because he was able to realize a higher quality of information from his research. The simplicity of it gave him more control over

How do we know we know what each individual gene does? One way to investigate the function of a gene is to just remove the gene and analyze what happens to the organism. Let’s say we have a gene of unknown function in the human genome‚ an unidentified gene. First‚ compare it to other genes to see what similar sequences they have‚ if they code some similar sequences they might code for similar functions. However‚ if the gene the unidentified gene codes for something different we have seen before this

Evidence for evolution includes: 1. The oldest to newest fossils clearly demonstrate without exception an overall progression of life forms from basic to more complex. If there was no evolution there would be no progression of species complexity over time. There are species that have existed relatively unchanged for millions of years referred to as living fossils. This is not evidence against evolution‚ only evidence that the traits of those particular species have been very successful for survival

11 Genetic and Environmental Influences on Human Development 11.1 Introduction We may often wonder about the reasons and forces which shape our personality and character. Each one of us has a specific kind of nature which takes that particuler form because of the effect of two major factors. The first is the genetic make-up which we inherit from our parents‚ and the second influence comes from the various experiences we have in our interaction with our surrounding environment. This includes

segregation and the law of independent assortment. The law of dominance stated that in a heterozygous condition‚ the dominant allele will dominate over another allele. This means that the dominant trait or phenotype will be present. The law of segregation states that for any trait or phenotype‚ the parent alleles will separate and only one allele from each parent will pass to the offspring. (O’Neil‚ 2011) The law of independent assortment states that different pairs of alleles are passed to each
