What is the probability that two heterozygous parents would have an offspring that produced round seeds?
The probability is 3/4 or 75%. If both parents are heterozygous for the seed shape trait (e.g., Rr), there is a 50% chance that each parent will pass on the dominant allele (R) for round seeds to the offspring. The probability of inheriting the dominant allele from both parents and producing round seeds is therefore (1/2) x (1/2) = 1/4 or 25%. Since there are two possible ways to inherit the dominant allele (from either parent), the total probability is 2 x (1/4) = 1/2 or 50%.
How does probability apply to heredity?
Probability applies to heredity with the inheritance of certain genes and alleles that together make up heredity. The question has to do with probability in that each parent cell can contribute one half of its genes. Because it splits through meiosis a parent cell can have one of two parts. The other parent cell has the same possibility of splits. Therefore, one half times one half is one fourth. That is the probability of each gene being passed on.
How does probability help explain the results of a genetic cross?
Genetics often involves dominant and recessive alleles. For instance, blue eyes are recessive and brown eyes are dominant.1 Each parent contributes one allele. If you get two blues, then your eyes are blue. If you get one or two browns, then you eyes are brown. That means that, given a random contribution from your parents, you have a 25% probability of blue eyes. It also means that, even though you have brown eyes, you could be carrying the blue allele, and two parents with brown eyes could have a blue eyed child. ------------------------------------------------------------------ 1Its more complicated than that, since eye color is actually polygenic, involving more than one allele. This example was simplified to answer the question.
Both parent organisms have brown fur Bb what is the probability that an offspring will have brown fur?
75%
What is the probability that the black parent of a black offspring was homozygous for black coat?
Well you see black people are useless. Whoever made the black child is obviously an ape of some sort.
What is the probability that he produces a gamete with the allele for attached earlobes?
The probability is 50% as there are two types of alleles inherited for an individual trait, with one allele being received from each parent.
Why deos A mother has one allele for dimples and one allele for no dimples What is the probability that she produces a gamete with the allele for dimples?
The probability that the mother produces a gamete with the allele for dimples is 50%. This is because each parent only passes on one of their two alleles for a given trait to their offspring, and in this case, the mother has a 50% chance of passing on the allele for dimples.
What is the probability of a gametes getting one of the parent's two alleles for a gene?
The probability of inheriting two alleles from the same person is 0%. The probability of inheriting an allele from each parent is 100%. You need more information for a more exact answer.
What gamete can be made of BB?
A gamete containing a BB genotype will carry one B allele from each parent. This gamete will contribute one B allele to offspring during fertilization.
A homozygous dominant parent will produce a gamete with?
A homozygous dominant parent will produce gametes with the dominant allele only. Each gamete will carry one copy of the dominant allele.
A gamete contains how many allele?
There is only one allele for each trait that goes into a gamete. This happens after meiosis as well. This process allows for DNA to be the same over time as reproduction continues.
Does a gamete only receive one allele or another from a pair?
A gamete receives one of two genes from one parent and one of two genes from the other parent.
What is Mendel's Principle of Segregation?
Mendel's Principle of Segregation states that during the formation of gametes, two alleles for each gene segregate from each other so that each gamete carries only one allele for each gene. This explains how offspring inherit one allele from each parent.
In a hybrid plant if every allele combination has two alleles what is the probability of one allele?
The probability of inheriting a specific allele in a hybrid plant would be 1/2 or 50%, as each parent contributes one allele and there are two possible alleles for a specific gene. Each offspring has an equal chance of inheriting either allele from the parent.
Mendel's law of segregation states that an organism inherits two alleles for any given trait one from each parent?
Mendel's law of segregation states that each organism carries two alleles for a trait, one from each parent, and during gamete formation, these alleles segregate randomly into separate gametes. This results in each gamete carrying only one allele for a given trait.
What process causes gametes to have only one allele?
In sexual reproduction each parent contributes only one allele to the offspring. This is why meiosis takes diploid cells and makes them haploid. The process meiosis separates the homologous pairs, separating the alleles from each other. Thus, each gamete produced has only one allele for each trait. When the male gamete (sperm) fuses with the female gamete (egg) and fertilization takes place, the resulting zygote has two alleles; one from the father and one from the mother.
What type of allele is known for skipping a generation?
Recessive alleles are known for skipping a generation. This is because the phenotype associated with a recessive allele is only expressed when an individual inherits two copies of the recessive allele, one from each parent. If one parent carries the allele but does not exhibit the trait, it can appear to "skip" a generation before being expressed.
