what is the mRNA codon for GTC
A cross was made between a white male dog and two different black females.The first black female gave birth to eight black pups,the second female gave birth to four white and three black pups.What are the likely genotypes of male parent and two female parent?
Huntington disease is a rare dominant trait that causes neurodenegeration later in life. A man in his thirties, who already has three children, discovers that his mother has Huntington disease though his father is unaffected. What are the following probabilties?
Dihybrid Crossing based on Mendel's Principle
In pea plants, yellow seeds(Y) are dominant over green seeds(y) and round peas(R) are dominant over wrinkled peas(r). Cross a plant that is heterozygous for both traits with a plant thas is homozygous recessive for both traits. Draw a punette square to show all possible offspring and determine the genotypic and phenotypic ratios

2. The Baltimore classification system (named for the Nobel laureate David Baltimore) is one of several methods of categorizing viruses based on their methods of protein synthesis and nucleic acid replication. There are seven major viral categories under the Baltimore classification system,
A) Design a dichotomous key differentiating the seven viral categories from each other.
B) Single-stranded RNA viruses are divided into two categories—the sense, or +, strand, and the antisense, or -, strand. Explain the differences in how viral mRNA (necessary for the production of viral proteins) is synthesized between the two categories. (Figure 13.17 should be of assistance.)
C) Part of the Baltimore classification system is based on a discovery that led to Baltimore being awarded the Nobel Prize in Medicine in 1975. Describe the connection.
D) Which Baltimore viral category would you classify a virus with the unusual genetic material of a DNA strand attached to a RNA strand? Explain and defend your response.
