Across
- 4. the process by which plants and animals give rise to offspring and which fundamentally consists of the segregation of a portion of the parental body by a sexual or an asexual process and its subsequent growth and differentiation into a new individual
- 6. having the two alleles at corresponding loci on homologous chromosomes different for one or more loci
- 10. the observable characteristics or traits of an organism that are produced by the interaction of the genotype and the environment : the physical expression of one or more genes
- 14. how different genes independently separate from one another when reproductive cells develop.
- 18. in a heterozygote, one trait will conceal the presence of another trait for the same characteristic. Rather than both alleles contributing to a phenotype, the dominant allele will be expressed exclusively.
- 22. temperature, food, pollutants, population density, sound, light, and parasites
- 23. money, property, etc., that is received from someone when that person dies
Down
- 1. a register recording a line of ancestors
- 2. a square diagram that is composed of a grid of usually four boxes and is used to calculate and depict all the combinations and frequencies of the different genotypes and phenotypes among the offspring of a cross in accordance with Mendelian inheritance
- 3. during the production of gametes the two copies of each hereditary factor segregate so that offspring acquire one factor from each parent.
- 5. A trait resulting from an allele that is independently and equally expressed along with the other
- 7. The trait that first appears or is visibly expressed in the organism
- 8. producing little or no phenotypic effect when occurring in heterozygous condition with a contrasting allele
- 9. all or part of the genetic constitution of an individual or group
- 11. the observable characteristics or traits of an organism that are produced by the interaction of the genotype and the environment : the physical expression of one or more genes
- 12. bred from members of a recognized breed, strain, or kind without admixture of other blood over many generations
- 13. to determine all or part of the genetic constitution of
- 15. The trait that is present at the gene level but is masked and does not show itself in the organism is called the recessive trait.
- 16. an animal or plant that is produced from two animals or plants of different kinds
- 17. a part of a cell that controls or influences the appearance, growth, etc., of a living thing
- 19. any of the alternative forms of a gene that may occur at a given locus
- 20. a branch of biology that deals with the heredity and variation of organisms
- 21. more important, powerful, or successful than most or all others
