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.
