Document Summary
Taillessness in manx cats- dd (dd lethal) Co-dominance or no-dominance- neither allele masks the other and are both expressed. Incomplete dominance or partial dominance- an allele is expressed in a dose dependent manner. Sex linked- expression of a gene that is located on the x chromosome. Sex limited- trait is limited to gender. Sex influenced- trait influenced by gender, an allele that is dominant in one sex is recessive in the other sex. Crossing over: occurs during initial meiosis. Mutation: insertion, deletion, substitutions of nucleotides. Myostatin- overlooks the growth and development of an organism because of its muscle growth. Hypertrophy- increase in cell size (sheep & cattle)
