Heredity Meiosis/Mitosis Protein Synthesis Punnet Squares and Pedigrees

Final Jeopardy!!! Draw a picture of protein synthesis, you need to include: A nucleus Ribosome mRNA Amino Acid Protein Chain

Row 1, Col 1 If Brown fur (B) is dominant in rabbits, give the genotype for a heterozygous brown rabbit. Bb

1,2 How many chromosomes does the human body have? 46

1,3 Proteins are long strands of what? Amino acids

1,4 In a pedigree, what shape Identifies males and what shape Identifies females? Square – Males Circle - Females

2,1 If Brown fur (B) is dominant, give the genotype of a homozygous recessive white rabbit. bb

2,2 ATG is a section of DNA. What would the codon and anti-codon look like for that 3 base code? Codon – UAC; Anti-codon - AUG

2,3 What are the two types of RNA? (I need the names!) Messenger (mRNA) and transfer (tRNA)

2,4 On a pedigree, what does a shaded in circle or square mean? That the person has the genetic trait.

3,1 If you crossed a heterozygous tall plant with a homozygous short plant, what percentage of the offspring would be short?

3,2 What is formed during Meiosis and how many chromosomes are in each of them? Sex cells; 23 chromosomes in each

3,3 What are TWO differences between DNA and RNA? DNA – double strand, has T as a base RNA – single strand, has U as a base

3,4 What is karyotyping? Taking an image of a person’s chromosomes or a visual map of a person’s chromosomes

4,1 What is the difference between purebred and hybrid and what is Another name for each? Purebred – same alleles; heterozygous Hybrid - different alleles; homozygous

4,2 Genetically, why do we get one allele from our mom and one allele from our dad? Because we get half of our chromosomes from each parent, so we get one allele for each gene from each parent.

4,3 What happens in Transcription and where does it occur? mRNA is made in the nucleus

4,4 Brown hair is dominant, blond is recessive. Draw a punnet Square for a blond dad and a Homozygous brown haired mom. What is the probability their children will have blond hair? Offspring – all Bb, 0%

5,1 What discovery did Mendel make when going from the P, F1 and F2 generations. That the recessive short allele is hidden in the F1 generation, but reappears in the F 2 generation.

5,2 What is different about the chromosomes in Meiosis I compared to Meiosis II? Meiosis I – the chromosomes are doubled and line up across the cell in pairs before dividing into two daughter cells. Meiosis II - the chromosomes are split in half and are then separated into 4 sex cells.

5,3 What happens during translation? Where does it occur? tRNA reads the mRNA and finds the correct amino acids to link together to form a protein in a ribosome

5,4 How many people have the recessive Hitchhiker’s Thumb trait (tt)? What genotype must the mother have (I-2)? 5 people, Tt
