What are three specific mechanisms by which sexual reproduction shuffles existing alleles? How does this benefit populations? Give one specific example. What is the basis for sex determination in various organisms? Why did genders evolve? Wouldn't it be more advantageous to have asexual or hermaphr...
Codominance: In this interaction, both alleles will be expressed. Answer and Explanation:1 Alleles are the variants of a gene. For example, garden peas have a gene that codes for colour. This gene has 2 alleles or variants - white or purple... Learn...
they are a low level toxin. The purpose of lectins is to discourage other animals from eating that life form. By triggering a negative reaction in the predator, that life form is then viewed as an undesirable food source. Hence, aiding its future survival. ...
up to four different alleles at a given locus, and have been shown to be responsible for genetic traits, susceptibility to disease, and response to drug therapies; fragment analysis can distinguish between these when dye-labeled nucleotides are used in pl...

If a first antiepileptic drug fails to control a child's epilepsy, what are the chances of success with the next drug? This study was carried out to determine how often a child's epilepsy is controlled and remits if a first antiepileptic drug (AED) fails to control seizures. We used the...
It talks about DNA profiles that examine peaks related to loci, specific locations on the chromosomes, and on how mixed profiles can confuse which alleles come from whom.GeddesLindaEBSCO_AspNew Scientist
aThe AMEL gene that encodes for female amelogenin is located on the X chromosome and AMEL gene that encodes for male amelogenin is located on the Y chromosome. The female has two identical AMEL genes or alleles, whereas the male has two different AMEL genes. This can be used to determine ...
Here, we used a global citizen-science database on bird attractiveness covering nearly all extant bird species, to show that there are specific visual features that drive our aesthetic appeal for some bird species over others. First, our aesthetic attraction is highest for smaller birds with ...
