recessive genotype Question 4: this trait would be represented by a "B" or "D" or "Z"
Answer:
dominent
Question 5: traits
Answer:
different forms of a characteristic (dimples: present or absent)
Question 6: phenotype
Answer:
physical appearance of a trait (ex: dimples, no dimples)
Question 7: DNA
Answer:
contains your genes
Question 8: homozygous
Answer:
two alleles/letters for one trait that are the same (DD or dd)
Question 9: nucleous
Answer:
contains DNA and controls cell activities
Question 10: gene
Answer:
factor that controls a trait you exhibit
Question 11: mitosis
Answer:
cell reproduction - when one body cell becomes two
Question 12: heredity
Answer:
passing of physical characteristics from parents to offspring
Question 13: genetics
Answer:
scientific study of heredity
Question 14: alleles
Answer:
letters that represent the different forms of a gene (dimples: D=present, d=absent)
Question 15: heterozygous
Answer:
two alleles/letters for one trait that are different (Ex: Dd)
Question 16: the letters that represent different forms of a gene
Answer:
alleles
Question 17: genotype
Answer:
combination of alleles (letters): DD, Dd, dd
Question 18: Bb, Dd, and Zz would represent a
Answer:
dominant genotype
Question 19: two alleles/letters for one trait that are different
Answer:
heterozygous
Question 20: recessive
Answer:
trait that hides in the background (lowercase letter) can only be expressed in homozygous form (dd)
Question 21: dominent
Answer:
trait that overshadows and is expressed (capital letter)
Question 22: two alleles/letters for one trait that are the same
Answer:
homozygous
Question 23: ribosomes
Answer:
makes proteins using directions from DNA
Question 24: Law of Segregation
Answer:
two parts of a gene pair of alleles separate from each other in the formation of sex cells. Half of the sex cells carry one allele and the other half carry the other allele
Question 25: proteins
Answer:
building blocks of cells that control your specific characteristics
Question 26: combination of alleles
Answer:
geneotype
Question 27: Law of Independent Assortment
Answer:
traits are on independently of traits from parent to offspring
