5. If you have the same two alleles for a trait, you are __________ or ______________ for that trait Homozygous or purebred

6. For Purple People Eaters having a long tail(L) is incompletely dominant to having (N)no tail, what type of tail would a PPE have if its genotype was LN Medium or short tail

7. What are the chances the offspring of a short tailed PPE and a long tailed PPE will have long tails? Short tails? No Tails? Long tails 50% Short 50% No tail 0%

8. In PPE’s Red noses and White Noses are co-dominant over green noses, show a Punnett square for a pink nosed PPE mating with a heterozygous white nosed PPE and give the probabilities for each possible phenotype Pink 25%, White 50%, Red 25%

20. Process in which DNA copies itself? DNA replication

21. Cell division that begins with DNA replication Your toss will be multiplied for each correct answer you write Mitosis, Meiosis and Binary Fission

22. Process in which DNA transfers its code to RNA Transcription

23. Make a chart showing three structural differences between DNA and RNA DNA has a different sugar RNA uses Uracil instead of Thymine RNA is single stranded, DNA is double stranded

24. Passing of traits from parents to offspring Heredity

25. Cell Division that produces genetically identical cells Mitosis

26. Cell division that only occurs in germ cells Meiosis

27. Cell division that produces gametes (sperm or egg cells) Meiosis

28. Cell division that involves crossing over, the exchanging of genes on homologous chromosomes; helps to ensure genetic diversity and uniqueness Meiosis
