enlarged testes. There is no cure‚ but there is some evidence that treatment of the associated behavioral and educational problems can be beneficial. Fragile X syndrome is caused by a mutation of the FMR-1 gene on the X chromosome (hence‚ fragile X"). Its connection to the X chromosome makes it sex-linked. The FMR-1 gene contains a sequence that consists of a variable number of repeats of the trinucleotide CGG‚ (representing cytosine and guanine). The sequence occurs in a part of the gene that is translated

Are Human Being naturally good or evil? Fundamentally speaking‚ are humans naturally good or evil? This is a question that has been repeatedly asked throughout humanity.

Chromosome 6 This book is more or less two stories being told at the same time and then morphing together towards the end. It begins at a doctor’s office in New York with the main characters Jack Stapleton and Laurie Montgomery. They are presented with a case concerning the murder of a mob member‚ Carlo Franconi.

Chapter 12 (Part 2) Explain the principle of independent assortment and its relation to meiosis: The segregation of chromosomes in anaphase I of meiosis explains Mendel’s observation that each parent gives one allele for each trait at random to each offspring‚ regardless of whether the allele is expressed. The segregation of chromosomes at random during anaphase I explains Mendel’s observation that factors‚ or genes‚ for different traits are inherited independently of each other. Apply the

Out of these‚ 22 pairs of chromosomes will account for physical characteristics such as your height‚ hair colour‚ skin colour etc. Which means that 1 pair of chromosomes are responsible in your gender. In order to give birth to a male baby there must be a Y chromosome in the form of XY which is given by the sperm cell‚ it is in the absence of this chromosome that female babies are developed‚ producing an XX chromosome balance.

Experiments had established that the allele for yellow seeds were the dominant allele (Y) and green seeds were the recessive allele (y). There were two different ways as to how seed shape and seed color would be passed onto offspring. One was independent assortment‚ which says that the allele for seed shape and the allele for seed color present in each parent
