Answer:
Each parent organism contributes one copy of its alleles in a seemingly random fashion to its offspring, as meiosis to create gametes (egg or sperm cells) reduces the number of genes by half. Therefore, each gamete contributes only one allele.
Explanation:
During meiosis process each parent contribute haploid gamete with an alleles for a specific gene in a random fashion to its offspring, Therefore, each gamete contributes only one allele.
What is allele ?
Alleles are the forms of a gene which carry a trait, it is present in a pair in a specific location on a particular chromosome and control the same trait.
Alleles of an organism makes the genotype.
If a pair of alleles are similar for a trait, then the genotype is homozygous.
If the pair of alleles are different for a trait, then the genotype of the organism called as heterozygous.
Similarly in a heterozygous genotype, the allele which express its character called dominant allele and the other one which wont express called recessive allele.
For example, the human blood group ABO.

Reginald Punnett sought to apply the insights obtained by Mendel to explain the laws of inheritance in a structured fashion. What's a Punnett square and how is it used? 3. You're conducting a science experiment crossing two different purebred mouse strains, which each contain a different variation of the same gene, for two generations. What do you expect to see as the phenotypes of the first generation? The second generation? 4. How closely do Mendel's insights into dominant and recessive traits match up with the ratios that Punnett calculated in his Punnett squares?
