Vocabulary: meiosis trait gene genotype phenotype punnett square homozygous alleles heterozygous dominant recessive mutation Law of Segregation Law of Independent Assortment
_______________1. This is a tool to display the possible results of a genetic cross. It allows you to predict possible outcomes of a cross.
_______________2. This is a characteristic passed from one generation to another.
_______________3. This is a trait that is always expressed if present in even 1 gene.
_______________4. This makes sex cells-reduces chromosome number to ½ the diploid number.
_______________5. This is when the genes are different … Bb
_______________6. This is when both pairs of a gene are the same…BB or bb
_______________7. A law of Mendel that says a parent’s genes separate during meiosis and only 1 allele is given to the offspring for each trait
_______________8. This is the genetic makeup for a trait- expressed as letters BB, Bb or bb
_______________9. A Law of Mendel that says traits are inherited independently from each other.
_______________10. This is a trait not expressed unless it is seen in both genes.
_______________11. These are the different forms of a gene. Ex. Eye color may be brown or blue
_______________12. The way a trait is expressed as a result of the genotype, what we see - blue eyes
_______________13. A change of DNA that produces a change in the proteins of an organism
_______________14. A segment of DNA that has the information to build a protein
Need a bit of “extra” help? Try these activities... complete and turn in.
http://learn.genetics.utah.edu/content/begin/dna/ for extra credit on this page view “What is DNA?” and “What is a Gene” then build a DNA molecule. Next, transcribe and translate a gene. Complete this activity hint: “MET” is the starting amino acid and has the code AUG... you will drag the orange met amino acid circle to the starting position (this is not the 1st base!) Write the sequence of bases in your mRNA or amino acids that you put together on a sheet to turn in.
*You can complete the “Who’s your Daddy” activity (intermediate) for extra credit
Study guide part 1: Reflection Questions
1. Which determines the other—phenotype or genotype? Explain.
2. In pea plants, the gene for purple “P” flowers is dominant over the gene for white “p” flowers?
What is the genotype of a heterozygous purple-flowered pea plant?
What is the genotype of a white-flowered pea plant?
3. How is the product of meiosis different from that of mitosis?
A squirrel normally has 40 PAIRS of chromosomes in its cells.
After MITOSIS occurs, how many pairs of chromosomes would be in each of the squirrel’s body cells?
After MEIOSIS occurs, how many pairs of chromosomes would be in each of the squirrel’s sex cells?
4. Respond to this: “Because the offspring develops inside the female, it will be more like her.”
5. Some offspring display more traits of their fathers and some display more of their mothers. If each parent donates one gene for each trait, how can this happen?
6. Hanging earlobes (H) are dominant over attached earlobes (h). Complete a Punnett square showing the possible offspring from an Hh male and an hh female. Then answer the questions.
- What are the chances of these parents having an offspring with hanging earlobes?
- With four offspring, will two definitely have hanging earlobes and two attached earlobes? Explain.
-If an offspring has attached earlobes, can we assume its genotype is hh? Explain.
-If an offspring has hanging earlobes, can we assume its genotype is Hh? Explain.
7. Occasionally a trait not observed in either parent appears in an offspring. How this can happen?
8. Which parent actually determines the sex of an offspring? Explain.
9. If a baby had the potential to be homozygous dominant, heterozygous, or homozygous recessive for a trait. What must be true about the genotypes of both of their parents for each trait?
10. Explain the relationship between DNA, Genes, Alleles and chromosomes.
11. Describe Down’s Syndrome.
12. Sickle Cell Anemia is a recessive disorder. Describe how what this condition does and how it occurs.
13. Color Blindness is a sex linked genetic disorder. What does this mean?
Usually sons inherit this trait through their mothers, explain how it works
