genetics

3. chromosome / Two chromosomes in a pair – normally one inherited from the mother and one from the father
6. the presence of a single set of chromosomes in an organism's cells
8. / a study of genes
10. / the production of offspring.
12. / one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
14. recombination /a process by which pieces of DNA are broken and recombined to produce new combinations of alleles
15. of independent / assortment how different genes independently separate from one another when reproductive cells develop.
16. /The presence of two identical alleles at a particular gene locus
17. / a reproductive cell of an animal or plantd
18. / The basic unit of heredity passed from parent to child.

1. /the union of two gametes
2. /having three or more sets of chromosomes
3. / An individual formed by mating between unlike forms, usually genetically differentiated populations or species.
4. / the relationship between two versions of a gene
5. / a trait that is expressed only when genotype is homozygous
7. /The observable characteristics in an individual resulting from the expression of genes
9. /The presence of two different alleles at a particular gene locus
11. the presence of two complete sets of chromosomes
13. of segregation /describes how pairs of gene variants are separated into reproductive cells
17. /a scoring of the type of variant present at a given location in the genome
