A large circle is drawn, with sectors of the circle identified to correspond to various stages of the cell cycle, such as the G1 (cell growth), S (synthesis) and G2 (cell growth) stages.

The 9:3:3:1 ratio can be modified if the loci are not simple dominant/recessive to each other, if there are gene interactions, or if the two loci are linked. A test cross gives a ratio of 1:1:1:1 for loci that assort independently. Take a look at this video, Mendelian Genetics and Punnett Squares, from Professor Dave Explains (2017), which gives a great summary of what we have covered so far!

Well, in those individuals with two of the same chromosomes (i.e., homogametic sexes: XX females and ZZ males), the chromosomes pair and segregate during meiosis I, the same as autosomes. Half of the offspring will receive two X chromosomes and become female, while half will receive an X and a Y and become male (Figure 10.3).

Transformation rescue refers to the incorporation of recombinant DNA molecule that contains a gene that is able to complement the mutated gene in another organism.

If you cross a homozygous, wiry-haired dog with a smooth-haired dog, what will be the genotype and phenotype of the F1 generation? If two dogs from the F1 generation mated, what would be the most likely ratio of hair phenotypes among their progeny?
