use structure mendels principles of heredity are listed on this page in a bulleted list. read the list carefully and answer the question below. ✔ two offspring from the same parents can have different phenotypes. how is this possible?

Explanation:

Mendel's principles include the law of segregation. During gamete formation, alleles segregate. Parents are often heterozygous. When they produce gametes, different combinations of alleles can be passed on. For example, if parents have the genotype \(Aa\), they can pass \(A\) or \(a\) to offspring. If one offspring gets \(AA\) (assuming another gene interaction or simple dominance - for a single - gene trait with dominance) and another gets \(aa\) (through segregation and combination), their phenotypes (if \(A\) is dominant) will be different.

Answer:

This is possible because of Mendel's law of segregation. Parents (often heterozygous for a trait) produce gametes. During meiosis (gamete formation), alleles segregate. Different combinations of alleles (from the segregated gametes) can result in different genotypes in offspring. If there is a dominant - recessive relationship (a common scenario in Mendelian genetics), different genotypes (\(AA\) vs \(aa\) for a simple single - gene trait with \(A\) dominant) will lead to different phenotypes.
