- Explain the importance of differential gene expression in developmentWhich of the following statements concerning genes are true? Select all that apply. A gene is a segment of DNA that determines a certain trait.A gene is a segment of DNA that determines a certain trait. An allele is a variation of a given gene. Genes contain information that codes only for proteins involved in the regulation of gene expression.Genes contain information that codes only for proteins involved in the regulation of gene expression. Genes are not responsible for the expression of traits.Genes are not responsible for the expression of traits. Allele variations are due to small changes in the nucleotide sequence within the gene that sometimes change the structure of a protein and ultimately its function.Allele variations are due to small changes in the nucleotide sequence within the gene that sometimes change the structure of a protein and ultimately its function.Which of the following is a correct order of events for limb development, from earliest occurring event to latest occurring event (for the three events in any given choice)? a.ZPA formation, Limb initiation/induction, Limb bud formation b.Limb placement, Fgf8 expression, ZPA formation c.Interdigital tissue regression, Fgf8 expression, Limb bud formation d.Limb placement, Interdigital tissue regression, Limb initiation/induction

Yes, all genes are either dominant or recessive B. No, all dominant genes are the best option but might not be expressed C. No, there are other factors that can determine gene expression D. Yes, all genes can be expressed if your cell wants to
