haploid X 23 in humans X 23 in humans diploid X 23 in humans Inheritance = The interaction between genes inherited from Mom and Dad.
Inheritance of blood types Mom = AB Dad = AB A or B A or B Gametes: Dad A or B Chance of each phenotype for each offspring 25% AA 50% AB 25% BB AA A or B AB Mom AB BB
Genotype Phenotype Genes code for proteins (or RNA). These gene products give rise to traits… It is rarely this simple. CB 14.6
CB 15.9 X/Y chromosomes in humans
CB 15.10 Sex-linked traits: Genes on the X chromosome A= normal ; a= colorblind No one affected, female carriers 50% of males affected, 50 % female carriers 50% affected, female carriers
CB 6.9 an Animal Cell Mitochondria
Endosymbiotic Theory - proposed origin of mitochondria and chloroplasts from free-living bacteria to cellular organelles CB 26.13
CB 47.6 Only the egg provides mitochondria to the offspring. mitochondria
CB 13.5 Mom provides 50.000275% and Dad provides 49.999825% of DNA to offspring. … because Mom provides 100% of mitochondrial DNA
Traits coded for by mtDNA are inherited only through mother mitochondria CB 47.6
Mitochondrial DNA comparisons can be used to trace ancestry:
The mutation rate in human mtDNA is one nucleotide change per 20,000 years. OR A difference of one nucleotide between two people indicates a common relative 10,000 years ago. Fig 4
