Document Summary
Sbe1 can have two diff dna sequences; resulting in smooth or wrinkled peas. The starch is packed in the pea so it doesn"t have space to be wrinkled : dominant. The recessive homo gene inactivates the enzyme; so water enters the pea and. If it was a heterozygous trait, it will still be smooth; r allele is dominant. Even though there is a recessive allele, the makes it wrinkled dominant allele takes up degraded enzymes and uses it again to keep the formation. Self-fertilization : taking the one trait and breeding it by letting it self-fertilize. Cross against a homozygous recessive phenotype for the trait in question. *uses a homozygous recessive trait to see if there"s any recessive trait in the gene* Can also tell if it is a true breeding organism. Can tell if it"s a heterozygous/ homozygous breeding trait. Probability of two or more independent events occurring together is the product.
