List and explain the four components of Mendel’s hypothesis that led him to deduce the law of segregation. • Alleles make different characters • Two alleles inherited • Dominance and recessive • Alleles segregate in gamete formation First‚ alternative versions of genes account for variations in inherited characters. A gene exists in different versions. Second‚ for each

Chapter 10 Foundations of Genetics Lecture Notes 1 Foundations of Genetics Mendel and the Garden pea The father of modern Genetics is Gregor Mendel. Gregor Mendel (1822-1884) was an Austrian monk who lived in a monastery where the experiments with the garden pea were performed. Mendel’s work with the garden pea was the fundamental study which unveiled the laws that govern genetics and heredity. Mendel was the first to use the scientific method in a very systematic and analysed his results

whether you or your son has this disease‚ your doctor will likely examine your (your son) genital area and proceed some tests such as hormone testing‚ chromosome analysis. This disorder is not inherited because it occurs as a result of a random error in gamete production process. Klinefelter syndrome often isn’t diagnosed until adulthood; however‚ there are many treatments that can help the patients minimize problems such as testosterone replacement therapy‚ breast tissue removal‚ educational support…

Dystrophyn is an important muscle protein which is produced in a gene in the X chromosome. Hence‚ it is a sex linked disorder that affects only boys. The boy‚ if he inherits

monohybrid and dihybrid cross. The ability to test these ratios stems from the use of Mendel’s law of segregation which states that during meiosis allele pairs will separate in gametes so one of each allele is present in a gamete. (Garey‚ et al‚pg 8-13) These single alleles are then combined with the other parental gamete forming a new somatic cell. Another important law is the law of independent assortment which means that different gene pairs will separate independently of each other allowing two
