Mendel's experiments discovered that one parent's trait disappeared in the F1 generation, only to reappear in one quarter of the F2 generation. Which of the following best explains this pattern of inheritance? A sperm or egg carries only one allele for each inherited trait because allele pairs segregate during gamete production.
There are alternative forms of genes that account for variation in inherited characteristics.
If the two alleles of an inherited pair differ, then one determines the organism's appearance and is the dominant allele.
For each characteristic, an organism inherits two alleles, one from each parent.
