What does it mean that an allele is "dominant" as opposed to being "recessive?" Whether an allele is dominant or recessive depends on: a. Whether it is inherited from the mother or the father. b. How common the allele is, relative to other alleles. c. Whether or not it is on a ...
Random mating prevents change in allele frequency(as described in Hardy Weinberg law) in a population when other evolutionary forces are not acting; though that does not happen in nature. Why is random mating important to Hardy Weinberg?
The molecular target of the acaricide amitraz is considered to be the octopamine receptor (OAR). Changes in the OAR sequence gene could be responsible of the cattle ticks becoming resistant to amitraz. A putative octopamine receptor was cloned and sequenced from a susceptible and an amitraz ...
The proportion of an allele in the gene pool as compared with other alleles at the same locus is termed as gene frequency.
One is purely green dominant, expressed as “GG,” each “G” representing an allele; the other is completely blue recessive, “gg,” which means this parent is actually blue in color. Since any offspring they have gets one allele from each parent, all of their offspring would have colorat...
Fixation refers to the case where one allele among several remains the only one in a population after the loss of the others. The effects of genetic drift are seen more readily or are greater in small populations because the genetic diversity is lost more quickly, and individuals are more ...
What is a silent allele? A silent gene formally designatesa rare (non-polymorphic, with frequency below 1%) recessive allele. Therefore, its presence can be unnoticed, even in large samples. ... Only when incompatible results are obtained (like apparent opposite homozygosity), the silent allele...
Provides a quick introduction of point mutation, which is a gene mutation that changes a single nucleotide base pair of DNA or RNA.What Is Point Mutation? - A point mutation, also called base-pair substitution, is a gene mutation that changes a single nucleotide base pair of DNA or RNA. ...
