Gregor Mendel and His Peas Questions predicting how traits would be transfered from one 1. Mendel was the first person to succeed in doing what? _______________________________________ to the other The monastery 2. Where was his garden? ________________________________________________________________ 3. Why did he work on pea plants?_becuase the reproduce sexually _______________________________ seven 4. How many traits did he study? __________________________________________________________ to control variables 5. Why did he only study one trait at a time? _________________________________________________ 6. What where the characteristics of the two pea plants he crossed first? Monohybrid one tall & one small The tall and short plants were a part of the P generation 7. What generation were they called? _______________________________________________________ 8. After the cross, what were they called? ____________________________________________________ a F1 generation that Mendel called the hybrid tall 9. What were the characteristics of the plants in the first cross? (tall or short) ________________________ 10. What happened when he crossed the “hybrid” generation plants? Every one of the offspring in the F1 generation were tall Genes exist in alternative forms called alleles. 11. Genes exist in alternate forms called what? ________________________________________________ Each of Mendel’s pea plants had two alleles of the gene 12. Each plant has how many alleles for each trait? _____________________________________________ that determined height lowercase uppercase 13. What kind of letter is used for a dominant trait? __________________Recessive trait?_____________ The dominant allele is always written ﬁrst 14. Which allele is always written first? ______________________________________________________ Homozygous 15. If a genotype has two of the same alleles (letters), TT or tt, it is said to be what? ___________________ yess 16. Can two organisms look alike but have different genotypes? ___________________________________ Heterozygous 17. If a genotype has two different alleles (letters), Tt, it is said to be what? __________________________ Reginald Punnett 18. Who came up with a short handed way of finding expected genotypes? __________________________ 19. If you know the genotypes of the parents, what can you use to determine the possible genotypes of the A punnett square offspring? __________________________________________________________________________ the phenotype 20. If you know the genotype, you will also know the what? ______________________________________ Based on your reading, fill in the blanks genetic traits 21. Genotype is the _________________ of an organism. physical traits 22. Phenotype is the _________________ of an organism.
