Genetics

4. each variant for a character e.g. round or wrinkled seed shapes
6. an alternative version of a gene
8. an allele which has no noticeable effect on an organism's phenotype
11. occurs when two alleles of the same gene are both fully expressed in an individual's phenotype
14. having inherited two different alleles of a particular gene — one from each biological parent
15. cells that have 1 set of chromosomes (1n)
17. an observable physical or chemical characteristic in an organism that be determined by both genotype and environmental factors

1. having inherited two identical alleles of a particular gene or genomic marker from both biological parents
2. cells that have 2 sets of chromosomes (2n)
3. reproductive cells that join together in sexual reproduction to form a new organism
5. the basic unit of heredity made up of a specific sequence of DNA
7. the genetic constitution of an organism (dependent on the DNA sequence within genes)
9. an allele which determines an organsim's phenotype
10. the single cell formed when a female egg cell and a male sperm cell combine during fertilisation
12. a heritable feature that can vary e.g. seed shape
13. the transmission of genetic info from parent to offspring
16. ________________ chromosomes - a matched pair of chromosomes
