What else can I help you with?
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.
What is the name of any of the two variants of a gene?
alleles
How many sets of same gene for every characteristic do offspring receive?
Two.
How many alleles do parents contribute to their offspring during reproduction?
Parents each contribute one allele for each gene to their offspring during reproduction. This means that offspring inherit two alleles for each gene, one from each parent.
A pink snapdragon has two genes that determine its color there is a white gene W and a red gene R the parent snapdragons only pass along one gene for color to an offspring What color will offspring be?
If the parent snapdragons pass along a white gene (W) to the offspring, then the offspring will be white. If the parent snapdragons pass along a red gene (R) to the offspring, then the offspring will be red.
How many of the offspring would be short?
It depends on the genetics of the parents. If both parents carry a short gene, then all the offspring would have a chance of being short. If only one parent carries the short gene, then approximately half of the offspring would be short.
If a cow with horns is bred to a polled bull will her offspring be polled?
Yes, the offspring has a 50% chance of being polled. The polled gene is dominant over the horned gene, so if the bull does not carry the horned gene, the offspring will not have horns.
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 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.
A gene is said to have multiple alleles if it has more than how many alleles?
A gene is said to have multiple alleles if it has more than two different forms or variants (alleles). This means there are more than two variations of the gene present in a population.
How are the 2 forms of a gene distributed to the offspring?
The two forms of a gene, one from each parent, are distributed to offspring during meiosis when sex cells are formed. Each parent contributes one allele of a gene to the offspring, determining the genetic make-up and traits of the offspring.
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.
