A list of the cell fibers from largest to smallest would read:

1. microtubules – is a microscopic tubular structure that is present in numbers in the cytoplasm of cells. These are usually aggregated to form complex structures.

2. intermediate filaments – are cytoskeletal components that is usually found in the cells of vertebrate species and other organisms like plants, fungi, unicellular organisms.

3. Microfilaments – are filamentous structures that can be found in the cytoplasm of eukaryotic cells and it will form part of the cytoskeletons. They are composed primarily of polymers of actin. But in cells, they usually interact with other proteins.

A vestigial-winged, hairy male is crossed with a wild-type female, homozygous at both genes. This F1 generation is crossed to pr

loris [4]

Answer:

The expected proportion of F2 individuals which are homozygous recessive at both genes is 1/16

All of the F1 generation will have the normal phenotypes for both genes

There will be no homozygous individuals in the F1 generation

Most of the F2 generation will have the normal phenotypes for both genes

Explanation:

A winged hairy male is crossed with a wild type female which is homozygous

Let the allele for vestigial trait be v

allele for wild trait be w

allele for hairy trait be h

Allele for non hairy be n

The genotype of parents would be

vvhh * wwnn

Thus in F1 generation all the offsrping will have normal phenotypes for both genes

In F2 generation

vwnh * vwnh

Out of 16 offspring only one wil be homozygous recessive i,e

wwnn

Rest all 15 will have normal phenotypes.

Hence, the correct answer is

The expected proportion of F2 individuals which are homozygous recessive at both genes is 1/16

All of the F1 generation will have the normal phenotypes for both genes

There will be no homozygous individuals in the F1 generation

Most of the F2 generation will have the normal phenotypes for both genes
