Blue-eyed mice interbreed and produce progeny with a 2:1 ratio of blue to non-blue. When blue is crossed with nonblue, a 1:1 rat
loris [4]

Explanation:

The results are explained if the trait blue eyes is dominant (B) over non-blue (b) and the dominant allele B is lethal in homozygous individuals.

<u>The possible genotypes and phenotypes are:</u>

  • Homozygous dominant (BB): lethal
  • Heterozygous (Bb): blue eyes
  • Homozygous recessive (bb): non-blue eyes

When blue (Bb) is crossed with non-blue (bb) the resulting offspring is 1/2 blue (Bb) and 1/2 non-blue (bb).

When non-blues interbreed (bb X bb) all progeny is non-blue (bb).

Both eukaryotes and fungi have a membrane-bound nucleus.
This is the reason why fungi are sometimes classified as eukaryotes. This means that their nucleus is protected by a thick layer of membrane.

Label all of the components of this DNA structure with the following terms: Phosphate sugar backbone, nitrogenous base, hydrogen
Hunter-Best [27]

Answer:

Phosphate sugar backbone:                                                                                              

The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.

Nitrogenous base:                                                                                              

Nitrogen bases are the molecules that make up the steps of the ladders. There are four different nitrogen bases, namely; Guanine, Thymine,Adenine and Cytosine.

Pyrimidines are compounds that make a single 6-sided ring. Examples of pyrimidines are Cytosine and Thymine.

Purines on the other hand make 5-sided and 6-sided rings. Examples of purines are Guanine and Adenine.

The nitrogen bases are helped together through hydrogen bonds.

Hydrogen Bonds:

A weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.
