Interpretation of some of the words used in genetics
To understand genetics easily,
you need to have a clear idea of the following terms.
1. Factor or Gene: A fragment of a DNA molecule that carries the basic structural and functional unit of an organism's heredity and the characteristics of an organism from generation to generation.
2. Locus: The specific location of genes on the chromosome. The alleles of a particular gene are located in the same locus of homologous chromosomes.
3. Allele or Allelomorph অপ A specific gene-pair located at a specific locus of a homologous chromosome pair.
It can be the same religion (eg TT) or the opposite religion (eg Tt). When there are two opposite alleles, one is a manifest allele (i.e. -T).
4. Homozygous:
In case of homosexuality, it is called hemaezaigas. For example- BB = black fur, bb = brown fur etc.
5. Heterozygous: Heterozygous organisms are heterogeneous if the two alleles that control a particular trait in an organism are abnormal. Such as T ab
6. Dominant character: H1 heterozygous organisms occur in a pair of opposite hemispherical organisms (TT and tt) when hybridization occurs.Features say. For example, F1, if the genus pea has one gene for both long and short symptoms and (Tt) only long features are revealed.
7. Receiving charaeter: In heterozygous organisms, when two elements of opposite properties are together, only one feature is revealed, the other
8. Phenotype: External symptoms of organisms controlled by genotype. It reveals the size, shape, color, etc. of the organism. Two creatures with identical phenotypes
9. Genotype: The formation of a pair of genes that control the symptoms of an organism is called genotype. The genotype of an organism is known from its predecessors or descendants.
10. Dibybrid cross: Hybridization or cross by looking at two pairs of opposite characteristics of an organism. Such as kalevarna-chhetlemdhar
11. Test cross 4 F, or F, in order to know whether the offspring of the genus Hemazegigus or Hetarazegigus will have a genus of pure progenitors.
12. Back cross Back F1, one of the parent species with a heterozygous organism. Hybridization with members.
