In some allele combinations, dominance does not exist.

Although not all combinations have a dominant allele, dominance does play a role in determining the phenotype when present. In some cases, both alleles may be expressed equally or result in a unique trait differing from the dominant alleles. It's essential to consider the influence of both dominant and recessive alleles in genetic inheritance.

What are all the possible combinations of allele that each F1 parent can pass on to the Offspring?
did
What information would tell you if a cross showed complete dominance?
If a cross between two organisms shows complete dominance, all individuals in the first generation (F1) will display the dominant trait. This indicates that the dominant allele is fully expressed, masking the recessive allele. To confirm complete dominance, further crosses involving the F1 generation can be conducted to observe the phenotypic ratio of the offspring.
When both alleles are expressed in an offspring this is called?
codominance. In codominance, both alleles contribute to the phenotype and are fully expressed in the offspring. This results in a distinct phenotype that is a combination of the traits associated with each allele.
Is the following sentence true or false all genes show simple patterns of dominant and recessive alleles?
False. Not all genes show simple patterns of dominant and recessive alleles. Some genes may exhibit co-dominance, incomplete dominance, multiple alleles, or polygenic inheritance, among other variations in genetic inheritance patterns.
When a red snapdragon is crossed with a white snapdragon all of the offspring are pinkwhat kind dominace does this show?
This shows incomplete dominance, where neither allele is completely dominant over the other. In this case, the pink color is a blend of the red and white alleles, resulting in an intermediate phenotype.

How do you determine the possible gametes in a dihybrid cross?
In a dihybrid cross, you first determine the possible gametes for each parent by independently sorting the alleles for each gene. Then, you combine all the possible gametes from one parent with all the possible gametes from the other parent to determine all possible genotypic combinations in the offspring.

What is a chart that shows all possible allele combination resulting from a genetic cross?
A Punnett square is a diagram used to predict the possible genotypes of offspring in a genetic cross. It displays all possible combinations of alleles that parents can pass on to their offspring.
What is an fixed allele APEX?
an allele present in all members of a population- APEX
What is and example of in complete dominance?
Complete dominance is when the presence of one allele ensures that the trait of the other allele is not displayed. For example, if B codes for black fur and b codes for white fur, a rabbit with Bb will have black fur. This is because the B shows complete dominance over the b - meaning that black fur will result. If this was incomplete dominance, a rabbit with Bb would have a mix - so grey fur. If it was codominance, a rabbit with Bb would have black and white patches, dots or splotches.
What is a fixed allele.?
An allele present in all members of a population
What type of allele is in all of the sperm nuclei?
Haploid alleles, which are single copies of each gene, are found in the sperm nuclei. This is because sperm cells are produced through meiosis, a cell division process that results in cells with half the number of chromosomes as the parent cell.
What type of allele is in the all of the egg nuclei?
the dominant allele is in all egg nuclei.
