Is the distribution of alleles present in the gamete nuclei after crossing over the same as that which was present without crossing over?
No, the distribution of alleles in the gamete nuclei after crossing over is generally different from that present without crossing over. Crossing over involves the exchange of genetic material between homologous chromosomes during meiosis, leading to new allele combinations. This process increases genetic diversity by creating recombination events that result in gametes with different allele distributions compared to those formed without crossing over.

What codominance is and give an example of codominant alleles explainiing why they are codominant.?
Codominance is a genetic phenomenon where two different alleles for a trait are expressed equally in the phenotype of an organism. An example of codominant alleles is the ABO blood group system, specifically the A and B alleles. When an individual inherits both the A and B alleles, their blood type is AB, displaying characteristics of both types without blending, which illustrates that neither allele is dominant or recessive. This results in both A and B antigens being present on the surface of red blood cells.
Explain segregation of alleles using pea plants?
if the pea plant has 2 recessive alleles then the plant is gonna come out short.but if it has 1 recessive and one dominant allele then the plant turns out tall, because the dominant allele can be present without the recessive allele.
What is the function of wire crossing without joining?
The wire that do not touch each other are dawn without blobs.
How do dominant lethal alleles persist in populations even though their fitness is essentially zero?
Huntington's disease, where the lethal allele expresses itself very late in an individuals life. Persons carrying the dominant lethal allele does not become aware of the disease until after their reproductive age. Thus, they pass the lethal allele to their children without knowing and the allele persists.
What statements is true of sex linked allele's?
Sex-linked alleles are genes located on the sex chromosomes, typically the X chromosome in humans. Because males have one X and one Y chromosome, they express any allele present on their X chromosome, making them more susceptible to X-linked recessive disorders. Females, having two X chromosomes, can be carriers of recessive alleles without expressing the trait if the other X carries a dominant allele. This difference in inheritance patterns can lead to varying expression of traits between genders.
Suppose that two alleles on one homologous chromosome are A and B and the other homologous chromosomes's alleles are a and b How many different genetic types of gametes would be produced without cro?
Four different genetic types of gametes would be produced without crossing over. These would be AB, ab, Ab, and aB.
Which of the following assort independently. a chromosomes b genes on the same chromosome c multiple alleles d co-dominate alleles?
the answer is C multiple alleles. The above answer is wrong. My son has the same question on his Biology homework. He chose the answer, multiple alleles and it was wrong. I believe the correct answer is, chromosomes!
If Laurie has albinism but neither of her parents exhibits this inherited condition the trait must be?
Recessive. This trait can skip generations, because it requires two recessive alleles (ex. aa vs Aa), and can be present in heterogeneous alleles (Aa) without showing a recessive phenotype.

What is a binary distribution?
A binary distribution is a distribution of software using executable binaries, without source code, or another term for Bernoulli distribution.
