dominant traits are not always more common or more likely to occur because you could be living on a small island that doesn't get visitors and almost everyone has this recessive trait the recessive trait would be more likely to occur when a baby is born

Multiple alleles in human traits Most human traits are controlled by multiple genes, and thus multiple alleles. Simple crosses and dominance relationships learned in an i…ntroductory biology course cannot adequately describe most human traits. Extreme traits (which can be dominant or recessive) such as straight or curly hair have been sexually selected against, which is called stabilizing selection. For example, this is why most people are of an "average" height. Head hair style is controlled by both hair texture, width, and oil content. Wavy hair is usually shown by individuals in the middle ranges of all of these traits. Different cultures sexually select for different traits,and there may be advantages to different traits in different environments, which explains why different races have unique hair types. In my family (an eastern-european one where about 25% of us have wavy or curly hair), the straighter genes seem to dominate the wavier/curlier ones. The curly-haired folks who married poker-straight spouses have produced almost excluively straight-haired children; the straight-haired folks who married someone who also had straight hair but whose family also exhibited some wave produced a few curly-haired variants; and the curly-haired ones who married other curly-haired partners produced 100% curly-haired children.
Dominant traits- is a strong trait Recessive traits- is a weak trait
Yes. When looking at Gregor Mendel's laws of inheritance, the Dominant allele will always be inherited by the offspring, as it is more potent than the 'weaker' recessive allel…e (unless the recessive allele is present in both parents; this can be in the form of Aa or aa, but it must be present in both for the recessive allele to be present in the offspring). There are other cases, though, such as co-dominance, in which recessive alleles are more likely to be present in the offspring, but speaking in general terms, it is the Dominant (ex. AA / Aa) alleles that show up more commonly in offspring than the recessive (ex. aa) alleles.
no, because dominant is different from recessive, its impossible to have a dominant-recessive trait because the dominant is when only one copy of the gene is present, while in… the recessive a trait that must be contributed by both parents in order to appear in the offspring, in short the dominant is for single parent, while in the recessive is a product of two parents.
They're not necessarily, but they can be. When a recessive trait is more common, it likely because it was advantageous to have that trait so the species evolved to have more o…f it in the gene pool. Also, since dominant traits are expressed over recessive traits, natural selection has more of an effect on them.
1. freckles: dominant no freckles: recessive 2. dark eyes: dominant light eyes: recessive 3. free earlobe:dominant attached earlbe: recessive 4. polydactilism (6 fingers… or toes): dominant 5 fingers or toes: recessive 5. normal chin: recessivecleft chin: dominant 6. can roll tongue: dominant cannot roll tongue: recessive 7. cannot fold tongue: dominant can roll tongue: recessive 8. straight pinkie: dominant crooked pinkie: recessive 9. widow's peak: dominant straight hairline: recessive 10. separate eyebrows: dominant uni-brow: recessive
why do you think they're called dominant traits genius ^^very rude^^ Actually, some recessive traits are more common in a POPULATION.
Many recessive traits are more common than dominant traits, such as the recessive trait for having no freckles..
A dominant trait is a genetic trait which may cause a hereditary condition, a recessive trait disappears or goes in the background and only shows in a few generations.
First of all alleles code for different traits all across an organism. Simply looking at it, a dominant allele is a trait that essentially "dominates" or is expressed over a r…ecessive allele. In theory every organism (that is not asexual) receives one allele from its father and one allele from its mother. If both of these alleles are dominant (homozygous dominant) than the dominant trait is expressed, if one is dominant and one is recessive (heterozygous) than still the dominant trait is expressed. However, if the alleles for both traits are recessive (homozygous recessive) than the recessive trait will be expressed.
Hemophelia is a recessive trait. By Aline Garcia
A dominant trait occurs when either both alleles are dominant or one allele is dominant and the other is recessive. This is because a dominant allele overpowers a recessive al…lele. In order to have a recessive trait both alleles must be recessive.
A recessive trait would appear more often than a dominant trait for two reasons. First, the dominant trait may be lethal, so that only those individuals with the recessive gen…otype will survive. Second, the majority of the alleles for a particular trait in a population may be recessive. This is the case for the number of digits on human hands. Almost everyone has five digits per hand, which is the recessive trait. This is because the vast majority of alleles for that trait are recessive in most populations. Very few people carry the dominant allele for six digits per hand. However there are isolated island populations in which the majority of people have six fingers.
polydactyly is a dominant trait ( surprisingly)..but by process of selective marriage ( i am 4geting d term.. but most possibly its eugenics) it has been repressed such dat it… is nt usualy seen compared 2 pentadactyly
In diploid organisms, if there is one recessive and one dominant allele of a gene, then the phenotype will be determined by the dominant allele.
because when you have and dominant and recessive trait the dominant we always show up
