What are characteristics passed from parent to offspring called?
genetic traits
What could cause a mutant fly embryo to develop two tail ends but no head?
This is called bicoid mutant phenotype, and is caused by a maternal effect gene which is a gene that, when mutant in the mother, results in a mutant phenotype of the offspring regardless of the offspring's genotype.
What does Mendel's hypothesis of inheritance state?
i dont know all about it but he says that the mother and the father both pass genes to their offspring even though they may not show for example their fathers blue eyes but they show their mothers green eyes. the blue eyes is a recessive gene they will pass to their offspring. so it may skipa generation and come back because the offspring carry that gene. no gene is lost until it has passed 2 generations without a mother or father having it of the offspring have it.
Meiosis aids in evolution because it does what?
Meiosis is when the male gene and the female gene combine chromosomes to make a child or offspring. This increases the diversity of genes in an individual, and allows that diversity to spread through the population, thus effecting evolution.
Do variations in populations lead to new species?
Variations in offspring are acted upon by natural selection: some offspring will be slightly more proficient at producing new offspring than others. This means that some alleles will promulgate throughout the population gene pool at a faster rate than others, resulting in a shifting frequency of incidence in the population gene pool. This is what evolution is: shifting allele frequencies in the population gene pool.
How many sets of the same gene for every characteristic do offspring?
Two.
How does the number of offspring affect the process of evolution?
Evolution is the change in allelic constitution of a population gene pool over time. As organisms reproduce, some variants reproduce less, others more, causing some alleles to increase their frequency in the gene pool, while other allele frequencies decline. It is the differential reproductive success of variants in the population that drives this change.
What is the name of any of the two variants of a gene?
alleles
How do you find possible phenotypes of offspring?
Mendel Diagrams. If the offspring gets a dominate gene from both parents, the offspring will exhibit traits from the dominate gene. If the offspring gets a dominate gene from one parent and a recessive gene from another, the offspring will exhibit traits from the dominate gene. If the offspring get a recessive gene from both parents, the offspring will exhibit traits from the recessive gene.
How many sets of the same gene for every characteristic do offspring receive?
Two.
How many sets of same gene for every characteristic do offspring receive?
Two.
Why did you color the offspring plant a different color than the tall parent plant?
Because the offspring has both the Tall gene and the short gene
Why is a son who receives the allele for combinations from his mother always colorblind?
Since the mother would be considered a carrier, the gene will be produced in the offspring. the son will receive that gene and will be colorblind.
How do the offspring of sexual reproduction compare to the parent?
The offspring has half of each of their parents' gene
What is the Mode of inheritance hemophilia?
Transmitted by a dominant gene. If that gene is inherited from either parent, the offspring will develop HD. If the gene is NOT inherited, then the offspring will not have HD- AND cannot pass the gene to their offspring.
How do you know if the recessive gene will be the recessive in the offspring?
If the recessive gene is present in both of the parents.
How many characteristics does each gene contral?
2 genes control each characteristic of an offspring. x
