Question
A fruit fly has two genes for eye color, but each of its sperm cells has only one. This illustrates
Options
A.independent assortment
B.linked genes
C.pleiotropy
D.segregation
Solution
Sol.(d) [Key Concept: Law of Segregation — Gamete Formation] This illustrates SEGREGATION (Mendel's Law of Segregation). Diploid organisms have two alleles for each gene, but haploid gametes (sperm, egg) contain only one allele of each gene pair. During meiosis, the two alleles of each gene separate (segregate) into different gametes. The principle states that allele pairs separate during gamete formation, and randomly unite at fertilisation.
