A coin flip can be used to the selection of alleles that leads to the genetic/physical makeup of offspring. Like a coin toss involves a 50/50 probability between heads & tails, the probability of offspring for inheriting either one of each parents alleles for each gene is also 50/50. Each parent has two alleles for each gene and passes one on to its offspring at random. The coin flip represents heredity. A baby's physical traits are produced based on probability determined by the traits of the parents. :-)
An allele causes a trait by either being dominant orrecessive or example, allele A will occur over allele a because it is dominant.
No allele can give an advantage
Allele frequency is the proportion of a specific allele in a population compared to other alleles at the same gene locus. It provides insight into the genetic diversity within a population and helps in understanding evolutionary processes such as genetic drift and natural selection.
No, a heterozygous genotype, which consists of one dominant and one recessive allele (e.g., Aa), will typically express the dominant trait, not the recessive one. However, if both parents are heterozygous (Aa), there's a possibility for offspring to inherit two recessive alleles (aa), which would express the recessive trait. Thus, while a heterozygous individual cannot express a recessive trait, such traits can appear in their offspring if the right allele combinations occur.
Mutation can create new alleles, therfore can change allele frequencies in a population.

Allelic diffrence in future generation can occur through chromosomal aberrations and mutaions.
through dominate and recessive genes
Recombination between linked genes can still occur because crossing over during meiosis allows for exchange of genetic material between homologous chromosomes. This process promotes genetic diversity by creating new combinations of alleles that can be inherited independently of each other. Additionally, the frequency of recombination between linked genes can be influenced by factors such as chromosomal structure and distance between the genes.
When cartographers represent the three-dimensional Earth in two dimensions what is likely to occur is distortion.
Since there are 6 sides on each die, and you have 3 dice, you do 6x6x6. Which is 216 combinations.
For a mutation to affect evolution, it must occur in the DNA of reproductive cells (sperm or egg cells) so that it can be passed on to offspring. Mutations that occur in somatic cells (non-reproductive cells) do not directly impact evolution as they are not inherited by future generations.
Spider syndrome caused by a recessive autosomal allele.
No, organisms die.Evolution is the change in allele frequency over time in a population of organisms.

No, stable allele frequencies do not prevent microevolution. Microevolution involves changes in allele frequencies within a population over time, even if those frequencies are stable for a period. Evolution can still occur through mechanisms such as genetic drift, selection, and gene flow, even if allele frequencies are temporarily stable.
