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 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.
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.
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.
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.
Can all the gene pairs from one parent can congregate in one gamete and those from the other parent in the other gamete?
No
How does the chromosome content of a parent cell compare with that of a gamete?
The gamete will have 50% of the genetic material of the parent. This is then fused with the other parent's 50% to give the offspring the whole 100%.

What is gamete for heredity?
if you are asking what one is, a gamete is a sex cell that has half the number the number of chromosomes from one parent. during fertilization, two gamete(one from each parent) combine. they are formed during meiosis.
Why do gamete contain less chromosome than parent cells?
The gamete is supposed to join with another gamete, and combine their chromosomes into a single cell.
How many different allele combinations would be found in the gametes produced by a pea plant whose genotypes are RrYY?
It depends on the allele combinations of the other pea plant parent. If the other pea plant parent also has a genotype of RrYy, then there are 16 combinations. If the other parent has genotype RRYY, then there are only 4 allele combinations. If the other parent has a genotype of RrYY, then there are 8 allele combinations in the gametes. If the other parent has a genotype of RRYy, then there are also 8 possible combinations in the gametes. Finally, if the other parent has the genotype rryy, then there are 4 gamete combinations.
Which parent's gamete decides the gender of a child?
The Father's.
How many allele do you get from each parent?
23 from each parent
