Genetics and Heredity Quiz

the alleles of two different genes get sorted into gametes independently

A fertilized egg resulting from the fusion of two haploid gametes

The laws of inheritance describe how traits are passed from parents to offspring, while the laws of dominance describe the interaction between alleles

<p>Homozygous refers to having two identical alleles for a particular gene, while heterozygous refers to having two different alleles for a particular gene. They are expressed in the offspring of a cross between two individuals.</p> Signup and view all the answers

<p>Incomplete dominance occurs when the phenotype of a heterozygous individual is an intermediate blend of the two homozygous phenotypes, while codominance occurs when both alleles are expressed equally in the phenotype of a heterozygous individual. Multiple alleles refer to the presence of more than two alleles for a particular gene.</p> Signup and view all the answers
