Usually, if a gene that affects a particular genetic trait is NOT located on a sex chromosome, then consequently (click all that apply) it is an autosomal gene. a diploid cell should have at least two copies of this gene during G1 phase. this gene will be absent from the genomes of gametes. this trait should appear with roughly equal frequency in males and females. this trait must be “dominant.”
