A mouse geneticist considers five homozygous recessive mutant strains of mice (1–5). All show pink eyes. Crosses were made using all possible pairs. WT indicates wild type eye color and M indicates mutant pink eyes. Complementation Test Table Mouse population Mouse 1 Mouse 2 Mouse 3 Mouse 4 Mouse 5 Mouse 1 M WT WT WT WT Mouse 2 M WT WT WT Mouse 3 M WT WT Mouse 4 M WT Mouse 5 M Based on these results, how many different genes were mutated in making these five lines?

A hybrid plant species is an allopolyploid with 2n = 20 chromosomes in its somatic cells. It was formed by combining gametes from two different diploid species, followed by chromosome doubling that resulted in a fertile hybrid. One parent species produces gametes with n = 6 chromosomes. What is the chromosome number in the gametes of the other parent species?
