Across
- 6. The first filial, or hybrid, offspring in a series of genetic crosses
- 16. determines the probability of two or more independent events by multiplying the probability of one event by the probabilities of the other events
- 17. organisms that produce offspring of the same variety over many generations of self pollination
- 20. having two identical alleles for a given gene
- 25. The situation in which the phenotype of heterozygotes is intermediate between the phenotypes of individuals homozygous for either allele
- 27. stating that when two or more characteristics are inherited, individual hereditary factors assort independently during gamete production
- 28. situation where the phenotypes of both alleles are exhibited in the heterozygote because both alleles affect the phenotype in separate ways
- 29. genetic makeup, or set of alleles, of an organism
- 30. Gene interaction in which the phenotypic expression of one gene alters that of another independently inherited gene
- 31. Offspring resulting from interbreeding of the hybrid F1 generation.
- 32. the mating or crossing, of two true-breeding varieties
- 33. A diagram used in the study of inheritance to show the predicted results of random fertilization in genetic crosses observed
Down
- 1. individual who is heterozygous for a given locus for a recessively inherited disorder
- 2. rule of probability stating that the probability of any one of two mutually exclusive events occurring can be determined by adding their individual probabilities
- 3. A single gene with multiple phenotypic effects
- 4. range of phenotypes produced by a single genotype due to environmental influences
- 5. An allele whose phenotypic effect is not observed in a heterozygote
- 7. cross between two organisms that are heterozygous for a character
- 8. observable physical and physiological traits of an organism determined by genetic makeup
- 9. An additive effect of two or more genes on a single phenotypic character
- 10. situation where the phenotypes of the heterozygote and the dominant homozygote are indistinguishable
- 11. heritable feature that varies continuously over a range rather than in an either or fashion
- 12. organism that is heterozygous with respect to two genes of interest
- 13. Any detectable variant in a genetic character
- 14. An organism that is heterozygous with respect to a single gene of interest
- 15. stating that the two alleles in a pair segregate into different gametes during gamete formation
- 18. cross between two organisms that are each heterozygous for both characteristics
- 19. observable inheritable feature that varies among individuals
- 21. allele that is fully expressed in the phenotype of a heterozygote
- 22. having two different alleles for a given gene
- 23. phenotypic character that is influenced by multiple genes and environmental factors
- 24. The parent individuals from which offspring are derived in studies of inheritance
- 26. A diagram of a family tree showing the occurrence of heritable characters in parents and offspring over multiple generations
