Final Report from Passaic High School

Genetic Project Passaic High School: Final Report

First we want to thank Steven's Institute of Technology and the staff involved in this great collaborative project. And we also want to thank all the participants' schools around the world. For us the bilingual/Transitional Biology class was very exciting to be part of it with all of you! We were able to complete the project on time as it was designed. The most important idea or scientific procedure for us was the integration of the WWW as a resource in our learning process. The outcome was excellent! And definitely we will recommend it to other science-math students in our school. Our suggestions to the leader of the project is: To Keep Up The Good Work! Mr. N.Holzman, and for the project itself we will add other variant like gender & nationality since we are a multi-ethnical school and we did so. We are greatly satisfied with final outcome! The procedure we use after we collect the data and merge it with other schools was Excel for the total sum, percentages, and convert it in to a graphic for better picture and understanding. The highest percentages was for Earlobes 66%/34%, white forelock w/20%/80%for dominant vs recessive traits. Color Blind was treated as a sex Linked. Which got us in other interesting fact of human genetic . if a sex linked trait is due to a recessive allele, a female will express the phenotype only is she is homozygote.Because males have only one locus , the term heterozygous, homozygous, are irrelevant for describing their sex linked genes. Any male receiving the mutant allele from his mother will express the trait. And by the way thanks for the site that provided us with the information, Cards with the numbers, and color for the color Blind test it were very helpful. In the general analysis we went over the Law of Probability and the third law of Mendel . The law of segregation operates according to the rule of probability. According to the rule of multiplication, the probability of a compound event is equal to the product of separates probabilities of the independent single event. Which help us to explain why some dominant traits were less frequents than their contra part recessive traits? The solutions are not always straightforward because of complicating variations. The recessive trait was expressed in the phenotype because the one parent must be heterozygous (Tt,tt) and the other was recessive homozygous and that also explain the 50/50 which require more quantity of data for the final explanation. An allele is classify as dominant if a single copy is sufficient to significantly affect the phenotype .We can't no assumed that a dominant allele will be more plentiful than it recessive allele in a population, without forgetting natural selection, and Hardy Weinberg Theorem. We concluded that despite intrinsic constraints involved in using humans for genetic research, Mendelians analysis applied to advance the understanding of our own inheritance.
