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.
IRA contributions made before the IRS Regular Tax Filing Deadline (usually April 15th) can be counted for either the current year or for the prior year, you choose. IRA contribution limits in both 2011 & 2012 were $5,000 and if over 50 during the tax year, $6,000.ou may make partial contributions until your income hits $131,000 ($193,000 for married). If your income is above that, you cannot contribute to a Roth IRA. If you are interested, there is a workaround called the Backdoor Roth IRA if your income is above the limits.
