A carrier of a genetic disorder who does not show symptoms is most likely to be to transmit it to offspring?
A carrier of a genetic disorder who does not show symptoms is most likely to be heterozygous for the trait and able to transmit it to his offspring. The term heterozygous refers to a pair of gene with one dominant trait and one recessive trait.
What might a series of helpful variations in a species result in?
According to the theory of evolution, it works like this: Every once in a while, an organism develops (having genes slightly different from its parents) that's different from its parents. If that difference is helpful to the survival of that organism or its children, which is very unusual, then that organism is likely to have more surviving offspring than others. It is said to be favored for survival. Over the course of many generations, we assume that the variation that increases surviving offspring will come to be the dominant (regular) characteristic in the population. Remember: evolution only happens to populations, not to individuals (except in fiction).
What happens when a dominant and recessive allele are both present?
The resulting offspring will have the dominant trait. It depends on if the dominant is hetero or homo...if it was homozygous then your offspring will have a hetozygous trait showing the dominant trait (to clear this up if you are confused lets say we are talking about brown eyes(BB-dominant) vs blue eyes(bb-recessive)--a homozygous would give you a brown eyed child with Bb and but if the person is heterozygous Bb and gets with a recessive you have a chance of getting Bb or bb giving you a possibility of a brown or blue eyed child)...wow i just made that way more confusing than it had to be
What are the various possible consequences of the overproduction of offspring?
The overproduction of offspring causes competition for limited resources such as food, water and space. Some individuals are better suited for the environmental conditions and they are more likely to survive and reproduce. Those who are less adapted will not survive or they may migrate to another area. This is known as natural selection.The overproduction of offspring can also increase the chances of diseases spreading in a population. The waste products of the population may also reach dangerous toxic levels. If the number of individuals exceed carrying then the population will crash.
What are the 4 key principles of natural selection?
1. Overproduction - more offspring are born than survive 2. Genetic Variation - there is variation in the population 3. Struggle to Survive - organisms with suitable variations will survive and reproduce 4. Differential Reproduction - suitable variations are passed on to offspring
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 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 the genotype of the offspring that do 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 is the percentage of the possible types of offspring had the same genotype as the parents?
Since there is no information on the genetic make up of the parents only a generalized set of answerscan be given.The chance of an offspring being genetically identical in every way to either or both of its parents is virtually nil.The percentages of individuals that match the genetics of the parents for a few traits can be determined through the use of a punnet square.For example considering a single trait where one parent is homozygous dominant and the other is homozygous recessive zero offspring will have the genotype of either parent.If the parents are heterozygous for a single trait 50% of the offspring will have the genotype of the parents for that trait.The more gene pairs considered the less likely an offspring identical to the parents is possible.
What percent of the offspring will most likely have brown fur?
for what animal. it all depends on the dominant gene (allele) and recessive. the genotype of the parents needs to be set up in a Punnett square and with that data you can determine the probability that an animal will have brown fur
What is receiving physical characteristics from a parent called?
That is most likely called the phenotype, as apposed to the genotype of the offspring.
What is probability how does probability relate to genetics?
Probability is what chance something has to happen. The Punnett Square is a way how to predict in genetics how likely an offspring is to have a trait passed on from parents, or in other words find out the probability of a trait being in the phenotype or the genotype.
Relate probability to the study of genetics?
Probability is what chance something has to happen. The Punnett Square is a way how to predict in genetics how likely an offspring is to have a trait passed on from parents, or in other words find out the probability of a trait being in the phenotype or the genotype.
How do genetics use the principles of probability?
Probability is what chance something has to happen. The Punnett Square is a way how to predict in genetics how likely an offspring is to have a trait passed on from parents, or in other words find out the probability of a trait being in the phenotype or the genotype.
How could the botanist best determine whether the genotype of the green-pod plant is homozygous or heterozygous?
The botanist could perform test crosses between the green-pod plant and a known homozygous recessive individual. If all offspring show the dominant green pod trait, the green-pod plant is likely homozygous. If the offspring display a mix of green and yellow pods, the green-pod plant is most likely heterozygous.
What is the transmission of characteristics from parents to offspring?
heribable
If some of the offspring of a test cross have the recessive trait then the genotype of the individual being tested is?
most likely to be 50% it makes more sense, you can also get 75%.
