What does being diploid mean for eukaryotes?most have 2 copies of all genes on chromosome, and 2 alleles of most genes on genome How did Mendel determine that pairs of factors must control genes?F2 had 3/4 yellow and 1/4 green An individual gene can have variation. These variations are called:alleles Why does meiosis occur?creates genetic diversity What is the key difference between meiosis and mitosis?in mitosis, the sister chromatids are identical together in meiosis, the divisions ...

The Drosophila embryo is patterned along its dorsoventral axis by a gradient of extracellular ligand. This ligand is called A) Dorsal B) Cactus C) Toll D) Pelle E) SpatzleE In the Drosophila embryo, the bicoid and oskar mRNAs are localized to the anterior and posterior poles of the embryo respectively. This localization depends upon nucleotide sequences located in which part of the RNA molecule? A) protein coding sequence
