Revision Mind Map for Genetics
Combination of alleles (BB - Homozygous Dominant, Bb - Heterozygous , bb - Homozygous recessive)
Physical expression of genotype/trait
Variation or different forms of a gene
Sections of DNA/Chromosomes that codes for a particular trait.
Long strands of DNA found in the nucleus of cells 46 chromosomes/or 23 pairs
Genetic code, Double helix shape/structure. Nucleotides - 1 base, 1 phosphate, 1 sugar. 4 bases = ATGC.
2 Parents (Male and Female), Slow Process, Variation in the offspring will survive in change in environment. Few offspring. Needs/Uses energy.
1 parent, fast, less energy, more offspring, no variation/clones. Offspring will all die if environment change.
Makes Gametes (Sperms + Eggs, Sex cells). DNA doubles - Cells Split - Cells split again. 8 chromosomes diploid #/double. 4 chromosomes haploid #/half.
Received from parents, DNA/Genes, Passed onto offspring via Gametes
Non - Inheritable
Caused by the environment, Cannot be passed onto offspring
