Genetic inheritance - AQA Our genes are inherited from our parents, and the different combinations of these genes make us unique. Visit the Learn Genetics website to go on an animated tour of the basics. Cell division that occurs only in the ovaries (oogenesis) and testes (spermatogenesis) and results in the production of gametes; 2 consecutive divisions; produces 4 new daughter cells each containing half as many chromosomes as the mother cell (haploid, n); nonidentical to mother cell; important for reproduction and genetic variability, Cell division that occurs in body cells (autosomes/non-sex cells); 1 cell division; produces 2 identical daughter cells with 46 chromosomes (diploid, 2n); used for growth tissue repair, genetic consistency in all body cells, Occurs in seminiferous tubules of the testes; Spermatocytes (diploid, 46 chromosomes) become spermatids (haploid, 23 chromosomes, nonmotile), then during spermatogenesis they become streamlined, develop a tail and are then called spermatozoa, Occurs in the ovaries; Oogonia (2n, diploid) become secondary oocytes (n, haploid), it then stops during Metaphase 2 during ovulation and then resumes it when it is fertilized (becomes an ovum), A person's physical appearance, determined by their genotype, The genes a person inherits from their parents, determines their physical appearance (phenotype), Pairs of genes that determine certain traits such ass eye color, Carry pairs of genes (alleles); Alleles that occupy the same location on the homologous chromosome govern the same trait, The gene that masks the expression of the second allele and is expressed (A), The gene that is masked by a dominant allele and is not expressed (a), When the homologous chromosome carries two identical genes, ex. More complex organisms, including humans, produce specialised sex cells (gametes) that carry half of the genetic information, then combine these to form new organisms. Study the life cycles of the cell and how they interact with the environment. [The sporophyte is the diploid, multicellular stage of the plant that produces haploid spores by meiosis.]. The chromosomes now have genes in a unique combination. Widow's Peak, Mid-Digital Hair, ABO Blood Groups, PTC Tasting, Autosomal Dominant; A and B genes are dominant over the O gene, Sickle Cell Anemia; Heterozygous offspring exhibits some signs (some cells are sickled while others are not) and function normally unless in low oxygen conditions and are resistant to malaria, When both alleles are present in an individual and both are expressed; Due to multiple alleles where some genes have more than two alleles, such as Blood Types; Type AB blood has both I^A and I^B present; Type O blood has ii, Most common blood type (45% of population), Least common blood type (4% of population), Located on the X Chromosome; Males only need one recessive gene to express the trait; ex. Which blood type do universal receivers have? You may remember this shot from the video pod cast. Chromosomes are found in the nucleus of a body cell in pairs.

What is an error that occurs when pairs of homologous chromosomes or sister chromatids fail to separate during meiosis? Errors in meiosis are the cause of chromosomal abnormality. In what stage of meiosis do homologous chromosomes separate? The result is 4 haploid daughter cells known as gametes or egg and sperm cells (each with 23 chromosomes 1 from each pair in the diploid cell). A final brief section contrasts sexual reproduction with asexual reproduction. During meiosis, the chromosomes of each pair usually cross over to achieve genetic recombination Explain how haploid and diploid cells differ from each other. The transmission of traits from parents to offspring is called heredity. The parental (P) generation is represented on the _____________ & _____________ of the punnet square. Cells divide only once. Calculate the wavelength of Mendel found that paired pea traits were either dominant or recessive.When pure-bred parent plants were cross-bred, dominant traits were always seen in the progeny, whereas recessive traits were hidden until the first-generation (F1) hybrid plants were left to self-pollinate.
