Cinnabar colored eyes (cn) and reduced bristles (rd) are autosomal recessive genes and lobe shaped eyes (L) is an autosomal domi
Morgarella [4.7K]

Answer:

The correct genotypic notation for a wild type with phenotypic characteristics: red eyes, long bristle and round eyes will be any of CNRDll, CnRdl, CnRDl or CNRdl if c, n, r and d are capable of independent assortment and CNRDl if they cannot.

Explanation:

The eye color and bristle size is coordinated by either recessive cn and dominant CN or Cn genes. The wild type in questions has red color eyes, which is a dominant trait coordinated by CN or Cn if c and n can undergo assortment independently or just CN if they cannot. The second characteristics of the wild type is long bristle. We were told that reduced bristle is coordinated by recessive rd Gene. Then the long bristle in our specimen wild type will have dominant genotypic notification of RD or Rd, depending if r and d can undergo assortment independently. The last trait is a round eyes, which is a recessive trait controlled by recessive allele l. Therefore, the combined characteristics of red eye color, long bristle and round eyes shape of the wild type will be CNRDl or any of CNRDll, CnRdl, CnRDl CNRdl depending on the segregation pattern of c, n, r and d.

What would be of most importance to goblet cells and other glandular epithelia?
konstantin123 [22]

The given question is incomplete as options are not provided, however the options  are as follows :

- Golgi bodies

-lysosomes

-microvilli

-multiple nuclei

Answer:

The correct answer is - golgi bodies.

Explanation:

Goblet cells and glandular epithelial cells are cells that produce and secretes a specific type of products that are termed as the mucin to protect the skin and layer mucous membrane they place.

These cells are characterized by a large amount of Golgi body and endoplasmic reticulum as they are involved in the exocytic pathway which means they secrete, glycoproteins, mucin, and other substances. Golgi bodies needed to modify, synthesis, and secretion.

Thus, the correct answer is - golgi bodies.

What combinations of alleles could result from a crossover between BD and bd chromosomes?
AysviL [449]

Answer:

Bb, Db , Bd and Dd

Explanation:

When a cross between two parents (having certain trait) is carried out , they share their alleles with each other to produce offspring with new traits. These offspring have gentically different allele combination as compared to their parents. A  genetic cross can be represented by a punnet square (as given below)

The cross between two parents with genotype "BD" and "bd" will result into the following offspring -

B D

b Bb Db

d Bd Dd
