Dominance in genetics is a relationship between alleles of one gene, in which the effect on phenotype of one allele masks the contribution of a second allele at the same locus. The first allele is dominant and the second allele is recessive.For genes on an autosome (any chromosome other than a sex chromosome), the alleles and their associated traits are autosomal dominant or autosomal recessive. Dominance is a key concept in Mendelian inheritance and classical genetics.n Rr individuals the R allele masks the presence of the r allele, so these individuals also have round peas. Thus, allele R is dominant to allele r, and allele r is recessive to allele R. This use of upper case letters for dominant alleles and lower case ones for recessive alleles is a widely followed convention.
For example, suppose you made a $3,000 annual contribution to a Roth IRA early in 2003, then got a larger bonus than you expected and found that your permitted contribution was only $1,800. Your excess contribution was $1,200.If you didn't correct the excess contribution for 2003, you had to pay $72 excess contribution tax (6% of $1,200). And if you left the problem uncorrected beyond the end of 2004, you owe another $72.our excess contribution was $1,200. If you didn't correct the excess contribution for 2003, you had to pay $72 excess contribution tax (6% of $1,200). And if you left the problem uncorrected beyond the end of 2004, you owe another $72.
You can double-check the rules and limits in the Roth IRA guide and traditional IRA guide to find out if you meet the requirements. If you do make a contribution before the deadline, youâll have two tax years to choose from. Make sure to pick the 2014 tax year. Hereâs one last reminder.tâs also the best way to supplement your retirement plan through work. The IRS didnât change the 2015 IRA contribution limits. Itâs still at $5,500 ($6,500 for those 50 and over). It may not seem like much, but it quickly adds up when you max out your contributions every year.
