What effect does stabilizing selection have on variation in a population?
Stabilizing selection reduces variation in a population by favoring the average phenotype, while selecting against extreme phenotypes. This can lead to a decrease in genetic diversity within the population as individuals with extreme traits are less likely to survive and reproduce. Over time, stabilizing selection tends to maintain a stable, intermediate phenotype.
Does selection operate on the genotype or the phenotype?
Selection operates on the phenotype, which is the observable characteristics of an organism. Organisms with certain phenotypic traits that increase their fitness are more likely to survive and reproduce, passing on their advantageous traits to the next generation.
How does DNA percentage work in determining genetic relationships between individuals?
DNA percentage is used to determine genetic relationships between individuals by comparing the amount of shared DNA. The higher the percentage of shared DNA between two individuals, the closer their genetic relationship is likely to be. This can help determine how closely related individuals are, such as siblings or cousins.
Would you expect there to be more children with the dominant phenotype or recessive phenotypewhy?
There would likely be more children with the dominant phenotype because it only requires one copy of the dominant allele to express the dominant trait, whereas the recessive phenotype requires two copies of the recessive allele.
What is the phenotype of TtCc?
The phenotype of TtCc would depend on what traits the genes T and C control. In general, if T and C are dominant alleles and control visible traits, the individual would likely exhibit the dominant phenotype for those traits. If T and C are recessive, the individual would need to be homozygous recessive (ttcc) to exhibit the recessive phenotype.
What phenotype frequency in a population changes after each generation which would most likely be causing this?
Genetic drift, natural selection, and gene flow are factors that can cause changes in phenotype frequency within a population after each generation. These changes occur as a result of random chance events, differential survival and reproduction of individuals, and the introduction of new genetic material from outside sources, respectively.
What is the difference between a likely event and a likely event?
the same
what causes the Phenotype frequency in a population to change after each generation. Which would most likely be causing this?
competition between organisms
How do you describe the difference between most likely and least likely?
likely and unlikely
The following seed phenotype a showed up in a generation of plants. Which alleles are recessive?
To determine which alleles are recessive in the seed phenotype, you would need to compare the phenotype of the plants with known dominant phenotypes. Typically, if a phenotype appears in a generation that resembles the parents but differs from the dominant traits, those traits associated with the appearance of phenotype "a" are likely recessive. Observing the inheritance patterns in subsequent generations can further clarify which alleles are recessive based on the phenotypes that re-emerge when homozygous recessive individuals are bred.
What is the difference between a likely event and an unlikely event?
It is more LIKELY to have a likely event than a UNLIKELY event.
Which gene mutation is less likely to result in a phenotype change and why?
phylogeny
What is the major difference between creative person and non creative person?
A major difference is that creative individuals tend to think outside the box, embrace new ideas, and approach problems from different angles. They are also more likely to take risks and explore new possibilities, whereas non-creative individuals may prefer routine and conventionality.
What was the phenotype of the offspring that did not share of the parents phenotype?
If both parents have the same phenotype, but the offspring did not share that phenotype, then it is likely that the parents have a dominant phenotype, but the offspring has a recessive phenotype, which means that the offpring's genotype would be homozygous recessive, and it's parents' genotypes would be heterozygous. For example, the parents may both have the genotype Bb, which gives them black fur. Approximately 25% of their offspring should have the genotype bb, which gives them the phenotype of white fur.
Differences between two sample averages are most likely to be statistically significant if?
difference is large
