What type of allele dominance occurs when both the alleles are active and expressed?
When both the alleles are expressed, it is called co-dominance or mixed dominance.
What is meant by alleles?
Allele frequency, or gene frequency, is the proportion of a particular allele (variant of a gene) among all allele copies being considered. It can be formally defined as the percentage of all alleles at a given locus in a population gene pool represented by a particular allele.
The number of times an allele occurs in a gene pool?
The frequency of an allele in a gene pool is determined by counting the number of copies of that allele in a population. This frequency can change through evolutionary processes such as genetic drift, natural selection, mutation, and gene flow. Tracking allele frequencies helps scientists study population genetics and evolutionary dynamics.
What is meant by the allele frequency?
An allele frequency measures how common certain alleles are in the population. "The distribution of alleles in a population" -Apex
What factor determines whether the frequency of the new allele will increase?
Which factor might determine whether the frequency of the new allele will increase in a population where a mutation occurs?

What is a variation of a gene that occurs at the same place on homologous chromosomes?
An allele is a variation of a gene that occurs at the same place on homologous chromosomes. Alleles can differ in their DNA sequence and can result in different traits or characteristics being expressed.

In a certain population the dominant phenotype of a certain trait occurs 91 of the time what is the frequency of the dominant allele?
p^2+2pq=.91-->q^2=.09-->q=.3-->p=.7-->p^2=.49 p^2+2pq+q^2=1.49+2pq+.09=12pq=.42 the number of AA alleles =140-->49*2 + 42*1=140the number of AA alleles=60-->42*1 + 9*2=60 So the frequency of the dominant allele is equal to the number of dominant alleles over the total number of alleles.Therefore 140/200=.7.7 is frequency of the dominant allele
Explain segregation of alleles using pea plants?
if the pea plant has 2 recessive alleles then the plant is gonna come out short.but if it has 1 recessive and one dominant allele then the plant turns out tall, because the dominant allele can be present without the recessive allele.
What is meant by allele frequence?
How often a certain allele (or trait) occurs in a certain population.
What are alleles and how are they inherited from parent cells?
Alleles are alternative forms of a gene that can occupy the same position on a chromosome. When an organism inherits alleles from its parents, one allele is typically inherited from each parent. This process occurs during sexual reproduction, where each parent contributes one allele to the offspring.
What type of allele dominance occurs when both alleles are active and expressed?
Either Co-dominance, where different parts of the organism display the different alleles (i.e. red and white flowers), or a combination of the two alleles (i.e. red and white alleles make pink flowers)
What is allel frequency?
Allele frequency is the frequency at which a particular allele occurs in a population. For example, the genes for eye color involves many alleles: blue, brown, green, hazel. etc. Allele frequency refers to how often each expression shows up in a population, so for example in America the allele frequency for blue eyes may be 25%, hazel 15%, green 5% and brown 50%, with 5% left for other minor alleles. This would mean approximately 50% of the alleles for eye color in the American population are the "brown" variant.
