Genetics Practice Problems‚ book #1 1. In peas‚ the gene for tallness is dominant to the gene for shortness. What offspring phenotypes and genotypes would be expected from the following crosses‚ and in what proportions? a. Heterozygous x heterozygous b. Heterozygous x homozygous tall c. Homozygous tall x homozygous short 2. If blue eye color in man is recessive to all other colors‚ could: i. Brown eyed parents have a blue eyed child

Sex linked genetic disorders Fragile x syndrome Sex-linked traits are genetic characteristics determined by genes located on sex chromosomes. Genes are pieces of DNA on chromosomes that carry information that are responsible for inheriting traits. Different forms of the same gene are called alleles. One allele for a certain trait is inherited from a mother and one from a father. These traits are passed down from parent to their offspring by sexual reproduction. Fragile X syndrome (FXS) or Martin-Bell

Hard engineering refers to the construction of physical structures to defend against erosive power of waves To protect a coast from erosion‚ people have built seawalls in front of a cliff or along the coast. A seawall is usually made of concrete. It acts as a buffer and absorbs energy of breaking waves especially during storms where the waves are strong‚ thus protecting the coast. A seawall shields and protects the coast from the direct impact of the incoming waves‚ thus reducing erosion. However

this machine is responsible for sparking an interest in how things work. My love for practical sciences‚ in addition to my innate fascination with technology used for practical and real purposes‚ has enabled me to discern my love for mechanical engineering. As a chubby 11 year old‚ I remember sitting glued to Discovery channel. An episode of the show ‘How it’s made’ featured the process used to create a gumball machine. Awestruck I learnt about the intricate parts that made this miraculous machine

Blood tests have revealed startling information about two of her three adult sons. Even though they were conceived naturally with her husband‚ who is definitely their father‚ the tests state that she is not their biological mother. How could she have given birth to someone

Genetic Information Resources Genetic information is complex and overwhelming and there are many resources available via the internet containing detailed facts on the subject. For this assignment‚ I will summarize information that is available from various genetic websites and who might find these types of sites useful. I will also select two abnormalities of sex chromosomes and two gene-linked abnormalities from Chapter 2 of our text entitled Child Development (Santrock‚ 2014) and use the information

Description of how genetic variation and genetic drift affects extinction of various species. http://highered.mheducation.com/sites/9834092339/student_view0/chapter20/simulation_of_genetic_drift.html http://anthro.palomar.edu/synthetic/synth_5.htm Genetic drift has many factors that can be linked to the extinction of a species. Genetic drift is a change in allele frequency which can rise or fall over time. Genetic drift lowers genetic variation every generation. The strength genetic drift depends on

How did the Drosophilia melanogaster impact Genetics? Thomas Hunt Morgan used Drosophila melanogaster for studying heredity. Morgan used the Drosophila melanogaster‚ known as the fruit fly‚ because it feeds on decaying fruit. It is small‚ about 3 mm long‚ and easy to raise in the laboratory; a thousand can be collected in a one-quart glass milk bottle. Moreover‚ it is fertile all year long and very prolific‚ producing a new generation every twelve days‚ or thirty generations per year. Not only

Mechanical engineering is a discipline of engineering that applies the principles of engineering‚ physics and materials science for analysis‚ design‚ manufacturing‚ and maintenance of mechanical systems. It is the branch of engineering that involves the production and usage of heat and mechanical power for the design‚ production‚ and operation of machines and tools.[1] It is one of the oldest and broadest engineering disciplines. The engineering field requires an understanding of core concepts
