What phenotypic ratio would you expect as a result of a test cross between a dihybrid organism and one that is homozygous recessive for alleles at two independent loci?
a. 3:1
b. 9:3:3:1
c. 1:1:1:1
d. 1:2:1
e. 9:4:2:1
Answer:
c. 1:1:1:1
Explanation:
When a heterozygous individual for two genes is test crossed with a double homozygous recessive individual, the progeny is obtained in 1:1:1:1 phenotypic ratio. This occurs as the heterozygous dominant individual forms four types of gametes in 1:1:1:1 ratio while the homozygous recessive individual would form only one type of gamete having one recessive allele for each gene.
For example, a test cross between TtRr (tall and red) and ttrr (short and white) would produce a progeny in following ratio=
1 tall, red: 1 tall, white: 1 short, red: 1 short, white
Here, T= tall, t= short, R= red, r= white
Which complementary DNA strand pairs correctly with the strand above?
A. 5’ CTAGCTAG 3’
B. 5’ GATCGATC 3’
C. 5’ CUAGCUAG 3’
D. 5’ CATCGATC 3’
Each base pair forms a "rung of the DNA ladder" by joining two complementary DNA nucleotide bases. Two linked strands of DNA form a double helix, which is a structure that resembles a twisted ladder.
Because they are complementary base pairs, adenine binds to thymine while guanine attaches to cytosine. The complimentary bases may unite to form a bond.
This aids in holding the DNA molecule's two antiparallel strands together to form the helix. The complimentary base pairing rule refers to this.
Cytosine pairs with guanine, while adenine pairs with thymine. The two strands are so complimentary to one another.
For instance, a complementary DNA strand will have the nucleotidesequence 5' CTAGCTAG 3' for a DNA strand with the nucleotide sequence 3' GATCGATC 5'.
Therefore, According to this rule, nucleotides A and T and bases G and C are always equally abundant in DNA.

Answer: e. 2.5 ml
Explanation:
According to the dilution law,
where,
= concentration of stock solution = 20X
= volume of stock solution = ?
= concentration of required solution= 1X
= volume of required solution= 50 ml
Thus 2.5 ml much of a 20X tricaine stock solution is needed to dilute in order to make your solution.
