Another layer of connective tissue, called the ____________ , extends inward from the epimysium and separates the muscle tissue
Lisa [10]
The layer of connective tissue, called the _perimysium_ , extends inward from the epimysium and separates the muscle tissue into small sections. these sections contain bundles of skeletal muscle fibers called _fascicles_ .
Additionally, bundles of contractile proteins called fibrils fill a muscle cell, called a fiber. Outside of each fiber, is the connective tissue endomysium. Bundles of fibers form fascicles, surrounded by perimysium. Bundles of fascicles and perimysium comprise the entire muscle organ, which is enclosed by epimysium.

Populations of the grasshopper Vandiemenella viatica possess different chromosomal fusions and inversions. Grasshoppers that are
svetlana [45]

Answer:

The options

a. New combinations of genes yielding genotypes of greater fitness

b. Few heterozygotes because of underdominance

c. Frequency-dependent selection, leading to fluctuations in fitness

d. Heterozygotes with greater fitness, owing to overdominance

e. A random assortment of genotypes because of genetic drift

The CORRECT ANSWER IS b.

b. Few heterozygotes because of under dominance

Explanation:

In genetics, underdominance (at times called "negative overdominance") is the opposite of overdominance.

It is the selection against the heterozygote, that leads to disruptive selection and divergent genotypes. It occurs in cases of inferior and reduced fitness (As in our case study, it is the different chromosomal fusions and inversions)

of the heterozygotic genotype to the dominant or recessive homozygotic genotype. It is unstable as it causes fixation of either allele.

Another example is the African butterfly species Pseudacraea eurytus, which makes use of Batesian mimicry to avoid predation. This species carries two alleles that gives a coloration that is alike to a different local butterfly species that is harmful to its predator. The butterflies who are heterozygous for this trait are observed to be intermediate in coloration and thus encounter an higher risk of predation and a decrease in the total fitness.
