Why do zygotes have different allele combinations from the gametes they result from?
When two gametes fuse to make a zygote, cross bridges form between the DNA from the two gametes. During cell division, the two gametes then separate, with some of the parts of gamete 1 being transferred to gamete 2 and vice versa. This recombination allows genetic diversity to occur.
A gamete with ABCDE alleles will therefore "recombine" with a gamete with FGHIJ alleles to make, for example, ABHDJ cells. The new sequence will be replicated in subsequent cells.

How many different non repeating allele combinations can appear in the gametes of a person with the genotype AABBCc?
There can be 4 different non-repeating allele combinations in the gametes of a person with genotype AABBCc: ABC, ACB, BAC, and BCA.
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.
What type of individual can produce gametes with two different alleles?
An individual that can produce gametes with two different alleles is typically heterozygous for a particular gene, meaning it possesses two different alleles at that gene locus (e.g., Aa). During meiosis, these alleles segregate, allowing for the formation of gametes that carry either one allele or the other. As a result, such an individual can produce gametes with different genetic combinations.
During the formation of gametes in a hybrid tall plantthe allele and the short allele stay together?
During the formation of gametes in a hybrid tall plant, the alleles for tall and short height do not stay together. They segregate and assort independently during meiosis, resulting in a random combination of alleles in the gametes. This allows for a variety of possible genetic combinations in the offspring.
According to the principal of segregation What will the gametes of a heterozygous individual be?
According to the principle of segregation, a heterozygous individual (with one dominant allele and one recessive allele, such as Aa) will produce gametes that carry only one allele for each gene. In this case, the gametes will be either A or a, resulting from the separation of the alleles during meiosis. Therefore, half of the gametes will carry the dominant allele (A) and half will carry the recessive allele (a).

What two types of gametes could result from AABb allele combination?
The two types of gametes that could result from the AABb allele combination are AB and Ab. This is because during meiosis, homologous chromosomes separate and randomly assort, leading to different combinations of alleles in gametes.
What type of individual can produce gametes with two different alleles?
An individual that can produce gametes with two different alleles is typically heterozygous for a particular gene, meaning it possesses two different alleles at that gene locus (e.g., Aa). During meiosis, these alleles segregate, allowing for the formation of gametes that carry either one allele or the other. As a result, such an individual can produce gametes with different genetic combinations.
In the process of meiosis which step explains the probability that a particular allele will be in a gamete?
The step that explains the probability that a particular allele will be in a gamete is the Law of Independent Assortment during meiosis I. This law states that alleles of different genes segregate independently of one another during the formation of gametes, leading to various combinations of alleles in the resulting gametes.
What gametes can be formed by an individual with the genotype Aa?
An individual with the genotype Aa can produce two types of gametes: one carrying the A allele and one carrying the a allele. This individual will produce equal numbers of gametes with the A allele and gametes with the a allele due to Mendel's law of segregation.
During the formation of gametes in a hybrid tall plantthe allele and the short allele stay together?
During the formation of gametes in a hybrid tall plant, the alleles for tall and short height do not stay together. They segregate and assort independently during meiosis, resulting in a random combination of alleles in the gametes. This allows for a variety of possible genetic combinations in the offspring.
What happens to alleles when gametes form?
When gametes are formed through a process called reproduction, where a male's gamete combines with a female gametes' cell and produces a zygote; the alleles for that are varied in different fertilized zygotes. For example a zygote could have two different alleles from the gene from the male and the female; G and g, thus it would be heterozygous. However at the same time another zygote could have the gene of GG which would be homozygous and pure green.
How many different kinds of gametes can a DdGgww individual form?
A DdGgww individual can form 4 different kinds of gametes. This is because during gamete formation, each allele pair segregates independently of the other pairs, following the principle of independent assortment.

What are the 4 gamete combinations?
The four gamete combinations arise from the segregation of alleles during meiosis. If considering a dihybrid cross (e.g., AaBb), the combinations are AB, Ab, aB, and ab. This occurs due to the independent assortment of the alleles for different traits, resulting in these four unique gametes. Each combination represents a different allele configuration that can contribute to offspring genetic variation.
