Answer #1

i) The ratio of males to females in a population is called the sex ratio. So with respect to Samonella poisoning, sex rario of infection is =296/567=0.52 i.e if 52 males are infected then 100 females will be infected.

ii) now the proportion of male salmonella cases =296/45346 =0.0065

And the proportion of female salmonella cases =567/45346=0.0125

iii) percentage of male salmonella cases =(296/45346)*100=0.65%

Percentage of female salmonella cases =(567/45346)*100 =1.25%

Simple Dominance with 2 genes A gene in cats causes them to be black (dominant) or brown (recessive). A second gene causes cats to be agouti (have stripes on their hairs) or non-agouti (solid colored hairs). If you did a dihybrid cross between two black haired agouti cats, what fraction of the offspring would be expected to have each phenotype? If a dihybrid black agouti cat mated with a brown cat that was heterozygous for the agouti gene, what fraction...
