Often different genes can interact in a way that influences the same trait. In the Blue-eyed Mary (Omphalodes verna), for example, there exists a gene with alleles that determine the color of flowers: blue or magenta. Another gene, however, controls whether the flowers have color at all or are white.
The regular price of buying miles from American is about 3.17 cents per mile ($29.50 per 1,000 miles plus a 7.5% Federal Excise Tax) â before a $30 Processing Charge per purchase â but with the maximum bonus offer, itâll actually drop your price down to just 2.02 cents per mile!
I think the important to keep in mind is that miles are only worth as much as youâd otherwise be willing to pay for a ticket. In other words, if you redeem 100,000 miles for a ticket which would cost $10,000 in cash, youâre not actually getting 10 cents per mile of value.
