Dominant allele that is always shown in the phenotype, never hidden Recessive allele that can be hidden in phenotype by dominant trait phenotype physical display of a trait genotype actual genetic makeup homozygous both alleles are the same (TT or tt) heterozygous alleles are different (Tt) chromosomes bundles of genes (humans have 23 pairs) sex chromosomes determine gender (XX is female, XY is male) autosome chromosome that isn't X or Y cross to breed the 2 rabbits gene part of DNA that codes for one trait answers to whole study guide: Genetics Study Guide Vocabulary/abbreviations you should know: 1. Dominant gene that will dominate the recessive gene, will hide it if in heterozygous genotype 2. Recessive gene that is dominated by the dominant gene, will be hidden by the other 3. Phenotype physical display or expression of trait 4. Genotype actual makeup of genes (TT, Tt, etc.) 5. Homozygous both alleles are same (TT, tt) 6. Heterozygous 2 different alleles (Tt) 7. Chromosomes extremely long molecule of DNA, humans have 23 pairs of these 8. Sex chromosomes X and Y chromosomes, ones that determine gender 9. XX female 10. XY male 11. Autosome nonsex chromosome 12. Punnett square tool for predicting likelihood of offspring having certain traits 14. Sexlinked (or Xlinked) trait trait on X chromosome, recessive allele more likely to be displayed by male than female (because female needs to receive 2 X's with recessive gene and male only needs to receive one) 15. Cross (as in cross a brown rabbit with a white rabbit) produces offspring 16. TT, Tt, tt homozygous dominant, heterozygous, homozygous recessive 17. Gene segment of DNA, codes for single protein 18. Carrier individual who has one copy of recessive allele (usually one that codes for a disease or bad trait); heterozygous so does not display recessive trait 19. II 5 (use of Roman and Arabic numerals to identify individuals in pedigrees) this means 2nd generation, 5th person born in that generation (like in the packet we looked at on Tuesday) 20. Gregor Mendel Austrian monk who worked with pea plants, first to identify and describe laws of genetics 21. Law of independent assortment describes the fact that most genes are inherited separately or independently 22. Law of segregation describes fact that in formation of gametes, each pair of chromosomes separates; different alleles separate so Hh mother can pass on either H or h, but not both 23. Allele different "choices" or version of same gene like blue or brown eyes 24. Gamete – sex cell, egg or sperm 26. Zygote fertilized egg, can grow into new individual 30. Why can’t we predict exactly how many males and how many females will be in any litter of puppies? can only predict using probabilities from Punnett square, cannot predict with 100% certainty what will happen Also, be able to work problems using Punnett squares. You should be able to calculate probabilities (chances) of each phenotype and genotype in offspring.
