Mandelian genetics

5. An organism having a pair of identical alleles of a gene for a particular trait
6. A cross between an organism of recessive phenotype with another organism of dominant phenotype but unknown genotype
8. Genetic composition of an individual; combination of alleles possessed by an individual
10. A cross between organisms of same generation for example the crossing between individuals in first filial (F1) generation
11. A hereditary unit consisting of a specific nucleotide sequence in DNA that determines specific phenotype of an organism.

1. An allele which express its phenotype even in heterozygous form // An allele that masks the effect of recessive allele paired with it
2. An organism having TWO different alleles of a gene for a particular trait.
3. The observable characteristics of an organism determined by genotypes
4. Specific position on a homologous chromosome where a gene is located
7. An allele that only express its phenotype when present in the homozygous form // An allele that its effect is masked by dominant allele paired with it
9. Alternative forms of a gene for a trait occupying the same locus on homologous chromosomes
