This will take awhile to complete. Tackle a 3 or 4 pages each day.

• Click on Classical Genetics  and read  the first 14 pages (page links on right panel).
• At the bottom of the screen you have many additional resources to explore (animation, video, etc...).  Please do explore these for each of the 14 pages.

RNA, Protein, DNA... Remember the order of these molecules in the Central Dogma of Biology? (In other words... what makes what?)

Describe the blending theory of inheritance. 

Why is this theory (blending) incorrect?

State the sex of each plant flower structure:

• carpal
• anther
• pollen
• ovule

Describe a reciprocal cross.

Will a red male and a white female give you the same results as a white male and a red female?

Where was Mendel from?

What new type of math allowed Mendel to find patterns in inheritance?

Mendel's Findings: A First Look at Phenotypic Ratios

What is a true breeding strain of pea plant?

Know the terminology for making a traditional Mendelian cross.

True breeding plants (P generation) produces hybrids in the ___ generation. Cross two of these hybrids and you produce the next generation called ____.

When it comes to the trait controlling the shape of a seed, which form is dominant? wrinkled or smooth?

Which one was being masked in the F1 generation? smooth or wrinkled

Mendel's Conclusions: Alternate Alleles and Dominance

Which cross is the self-cross? P cross, F1 cross or F2 cross

Define gene.

Define allele.

Define Law of Segregation.

By figuring out the Law of Segregation, Mendel basically discovered _____.  
[Mitosis, Meiosis, nondisjunction, photosynthesis, New Jersey]

Mendel's Conclusions: Segregation and Recombination

What letters (genotype) go with the following:

• true breeding smooth
• true breeding wrinkled
• hybrid (F1) smooth
• a wrinkled one from the F2 generation

Which one(s) is (are) homozygous?  SS, Ss, ss

Which one (above) is heterozygous?

Distinguish between genotype and phenotype.

Remember you always have two alleles (one on each homologous chromosome). As long as one of those alleles is dominant, it really doesn't matter what the other one is (dominant or recessive). SS has the same phenotype as Ss.
