What else can I help you with?
Are dominant alleles naturally better for an organism?
No, recessive alleles are equally likely to be inherited (if your dealing with only those two types of alleles). BUT, dominant alleles are the ones that show up. That is precisely why they are called dominant. Compared to recessive alleles, dominant ones will overrule the others, making it the one inherited.
What causes a wide range of phenotypes for some traits?
Some traits, such as eye color and hair color, have multiple alleles that control different aspects of the phenotype. Because there are multiple different possible combinations of alleles, you get a wide range of phenotypes.
What do dominant and recessive alleles have in common?
Alleles are different types of a gene. Each gene controls a characteristic and they is usually a recessive allele and a dominant one. The main similarity is that they both control a certain characteristic!
How does a recessive trait show up as a visible trait?
Recessive alleles are only expressed in the phenotype if the organism is homozygous for the recessive allele (assuming diploidy). If the trait is sex-linked, then it will always show up in males if passed.
The standard for comparison in a experiment?
The standard for comparison in a experiment is known as a control variable. This is useful to any experiment and serves as a reference point used to draw conclusions.
What is the genotype of the control bulls he should use to test for the heterozygous genotype?
To test for heterozygosity, the control bulls should have a homozygous genotype. Using two bulls with the same homozygous genotype would be ideal for comparison when looking for heterozygosity.
The two or more related genes that control a trait are known as?
alleles
When than two alleles control a trait?
The presence of more than two alleles that control a trait is called multiple allele. An example of this is the group gene of ABO blood that has three alleles.
What is an organism that has two different alleles called?
There are three alleles, the dominant, uppercase 'T', and recessive, 't'. There is also codominance, which is when two separate alleles neither control and create something entirely diffierent ie: Straight haid allels, 'S', and curly hair allele, 'C', create wavy hair. The correct answer to this question is: Heterozygot. An organism with the same alleles at a gene locus is called a Homozygot. Hetero- often meaning "different" as in "Heterosexual -> different sex attraction " and "Homo-" often meaning "same" as in "homosexual -> same sex attraction".
How many alleles control blood type in humans?
2
Do alleles control phenotype?
Yes, alleles are variations of a gene that can affect the phenotype of an organism. The combination of alleles an individual carries determines specific traits or characteristics that are expressed.
When more than two different alleles control a trait?
This phenomenon is known as multiple allelism, where there are more than two different variations of a gene (alleles) that can affect a single trait. In this case, individuals can inherit one of several possible alleles for the trait. Examples include the ABO blood group system in humans, where there are three alleles (IA, IB, i) that determine a person's blood type.
What does your genotype control?
Genotypes control different physical characteristics. For example, Hair Color, Eye Color, etc.
What units found on a DNA molecule that contain control traits?
Alleles
How can the alleles that control that trait be described?
One dominate, one recessive
What has same alleles?
Two or more genes which control the same characteristic.
What are the two alleles that control the appearance of a trait?
Dominant and Recessive Alleles Diploid organisms typically have two alleles for a trait. When allele pairs are the same, they are homozygous. When the alleles of a pair are heterozygous, the phenotype of one trait may be dominant and the other recessive.
