Mutations in introns are less likely to affect phenotype then mutation in exons?
mutation in exons are less likely to affect phenotype then mutation in introns because mutaion in exons are silent mutation
Which gene mutation is less likely to result in a phenotype change and why?
phylogeny
Do most of the complex phenotype we observe come from a single gene?
No. A phenotype is what we see. The Human Genome Project has revealed that there are probably about 20,000-25,000 protein coding genes. There are most likely thousands more that have not been identified.
Organisms in which a circulating body fluid is distinct from the fluid that directly surrounds the bodys cells are to likely to have what system?
closed circulatory system!! blood fluid is DISTINCT from the body cells
What an organism looks like as a result of its genes?
For the sake of simplicity the discussion here will be of mendellian genetics. The way an animal looks (phenotype) may only represent a portion of it's genotype since dominant traits mask the expression of recessive ones. Behavior is not explained by genetics in many cases...the more complex the organism the more likely behavioral nuance is affected by elements beyond genetics.
Which type of inheritance is most likely to display a bell curve of phenotypes?
polygenic
Mutations in introns are less likely to affect phenotype then mutation in exons?
mutation in exons are less likely to affect phenotype then mutation in introns because mutaion in exons are silent mutation
Which gene mutation is less likely to result in a phenotype change and why?
phylogeny
What phenotype frequency in a population changes after each generation which would most likely be causing this?
Competition between organisms would most likely cause the phenotype frequency in a population that changes each generation.
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.
What is most likely to cause no difference in phenotype between two individuals?
There are many things that will cause no difference in phenotype between two individuals. One of these things is the water they drink.
What was the genotype of the offspring the did not share 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.
What does Distinct possibility mean?
very likely to happen
Can a child be afflicted with a dominant trait if both her parents have a normal phenotype Why or why not?
YES SOMETIMES THAT IS NOT LIKELY.
What is receiving physical characteristics from a parent called?
That is most likely called the phenotype, as apposed to the genotype of the offspring.
Do most of the complex phenotype we observe come from a single gene?
No. A phenotype is what we see. The Human Genome Project has revealed that there are probably about 20,000-25,000 protein coding genes. There are most likely thousands more that have not been identified.
what causes the Phenotype frequency in a population to change after each generation. Which would most likely be causing this?
competition between organisms
