IN THE TEST CROSS
UNKNOWN HYBRID IS CROSSED WITH HOMOZYGOUS DOMINANT PARENT
UNKNOWN HYBRID IS CROSSED WITH HETEROZYGOUS PARENT
UNKNOWN HYBRID IS CROSSED WITH HOMOZYGOUS RECESSIVE PARENT
NONE OF THE ABOVE
T H MORGAN EXPERIMENTALLY VERIFIED CHROMOSOMAL THEORY OF INHERITANCE BY USING Drosophila melanogaster BECAUSE
IT COMPLETES ITS LIFE CYCLE IN ABOUT TWO WEEKS
IT PRODUCES LARGE NUMBER OF PROGENIES IN SINGLE MATING
MALE IS DISTINCT FROM FEMALE
ALL OF THE ABOVE
ONE TRAIT CAN BE INFLUENCED BY MORE THAN ONE GENES,THIS IS THE CASE OF
PLEIOTROPY
POLYGENIC INHERITANCE
CODOMINANCE
ALL OF THE ABOVE
Coat color in a dog breed is determined by incomplete dominance where three colors are produced (Brown, tan and white), and the brown coat allele (B) has incomplete dominance over the white coat allele (b). Which offspring ratio would be expected from a cross between a brown dog and a white dog?
A. 2 BB: 2 Bb
B. 4 Bb
C. 1 BB: 2 Bb: 1 bb
D. 2 BB: 2 bb
A cross between a red flower and a white flower produces red and white spotted flowers. Which type of inheritance pattern is indicated by these results?
A. polygenic
B. codominance
C. multiple alleles
D. incomplete dominance
Human blood type is determined by multiple alleles (A, B, and O). Which ratio would result from a cross between a man with Type AB blood and a woman with Type O blood?
A. 50% Type A, 50% Type O
B. 75% Type A, 25% Type B
C. 50% Type A, 50% Type B
D. 100% Type O
Which principle best explains why the gametes only each contain a single allele?
A. Mendel's Law of Dominance states that dominant alleles must separate from recessive alleles in gamete formation.
B. Mendel's Law of Inheritance states that only one allele is inherited from each parent and the dominant allele is inherited first.
C. Mendel's Law of Segregation states that alleles must segregate during gamete formation in order to create haploid sex cells need for reproduction.
D. Mendel's Law of Independent Assortment states that each trait is inherited separately and the resulting gametes each only contain the DNA for a single trait.
A. Cell Theory
B. Law of Segregation
C. Law of Probabilities
D. Law of Independent Assortment
