What is it called when two different alleles of a gene are expressed?What do we call the term used to refer to an organism that has two identical alleles for a particular trait?Individuals with two of the same alleles for a trait are said to be ___ for that trait....
Alleles are two or more alternative forms of a gene that arise by mutation and are located at the same place on a chromosome. It is of various types like lethal alleles, multiple alleles, etc. Answer and Explanation: When there are more than two alle...

Sex mosaicism, also called gynandromorphism, refers to an accidental phenomenon in dioecious organisms (mainly animals) in which an individual phenotype includes both female and male characteristics. Despite the rarity of this phenomenon, elucidating the mechanisms of naturally occurring sex mosaicism sho...
Each of the various DNA sequences at one locus is called an allele: for instance, if there are three sequence variants present, then there are three alleles. Offspring inherit one homologous chromosome from each parent. Thus, a genotype comprises two alleles: the allele inherited from the ...
Gene which suppresses other gene's activity but does not lie on the same locus is called as View Solution The phenomenon in which genes have two or more alleles that are common in a population is known as View Solution Onion bulb shows white coloration instead of red - yellow pigmentation...
(alleles having the same mutation profile in the sequence selected in (a)) and the exclusion of one of the members of the said pairs; (e) the identification and the enumeration of the obligatory mutations or the so-called allele marker mutations, that is to say those which are required ...
In addition to those 3 alleles, there are additional alleles that specify weak expression of A or B antigens (phenotypically called as A2, A3, Aweak, Ael, B3, Bel, etc.). The molecular mechanisms responsible include mutations in the promoter/enhancer regions of the ABO gene that cause a ...
gene migration, happens multiple times. if the same change occurs by chance, it is called v. sometimes the change in allele frequency is so different in the new sample of population that they become a diffrent species. The original drifted population becomes founders and the effect is called ...
(1996) studied 315 siblings, most of whom were males, family members, and unrelated individuals from the United States and found an association of so-called long alleles (DRD4*7R and DRD4*8R) with novelty seeking; stratification was excluded as an explanation, on the basis of the sibling-...
