What is it called when neither allele for a trait is dominant?
There are two cases where this can happen: Case 1: Codominance: Both alleles are equally present but are distinct. a good example of this is when you breed a white cow with a red cow. both white and red are dominant. when you look at the offspring, it is roan; it has both white and red hairs mixed in with each other. Case 2: incomplete dominance: Both alleles are equally present but are not distinct. a good example of this is is when you mix a white flower and a red flower and you get a pink flower
Two different forms of the same gene are called?
Alleles
Why does each parent organism in the f1 generation have four alleles listed in figure 6.17?
Each parent has two genes with two alleles so there are four alleles.
What is the gene pair consit of dominant alleles or to two recessive alleles?
homozygous
In Model 3 two of the light alleles were lost (through the death of the individual who had these two alleles) before reproduction occurred in the 1st generation how did this affect the distribution of?
In Model 3 two of the light alleles were lost (through the death of the individual who had these two alleles) before reproduction occurred in the 1st generation how did this affect the distribution of the three alleles in this small population?
When two alleles for one trait are present and neither allele overshadows the other is demonstrated.?
incomplete dominance
When two different alleles appear on on gene but only one of those alleles appears in the phenotype is demonstrated?

When two different alleles appear on one gene but only one of those alleles appears in the phenotype is demonstrated.?

When two different alleles appear on one gene but onely one of those alleles appears in the phenotype what is demonstrated?
complete dominance
When two different types of alleles appear on one gene but only one of those alleles appears in the phenotype what is demonstrated?

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.
When two different allels appear on one gene but only of those alleles appears in the phenotype is demonstrated?

Two different forms of the same gene are called?
Alleles
A husband and wife have two sons one boy has a straight thumb while the other has a bent thumb what causes the difference?
The brothers have different alleles. They received different alleles from their parents
When more than two different 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 a gene pair called when is consist of two dominant alleles or two recessive alleles?
Homozygous
