The term genetic mutation described a change of the sequence of a DNA molecule. Genetic mutations source an enduring change in the classification of base pairs which is DNA-building blocks that creates up a gene. Mutations can affect a single base pair or it can affect a larger segment even as well as multiple genes. When mutations are inbred from a parent they are existing in almost every cell of the body. This in contrast with acquired mutations that can occur at any time in a person’s life and are present in only in a subset of cells in the body. Developed mutations can be caused by environmental factors such as ultraviolet radiation from the sun, or when a cell itself makes a mistake in copying its DNA during cell division. The DNA sequence can be altered in different ways and each type of mutation can have varying effects on the health of a cell, tissue and/or individual.

In cocker spaniels, black color (b) is dominant over red (b), and solid color (S) is dominant over spotted (s).
Levart [38]

Answer:

<h2>e) 3/4 </h2>

Explanation:

As given;

Black (B) is dominant over red (b), so B is dominant over b.

Solid (S) is dominant over spotted color(s), so S is dominant over s.

Offspring of BBss and bbss individuals are:

Gametes of parent BBss are Bs, Bs and gamete of bbss are bs, bs

offspring are : all Bbss

Cross between these offspring is; Bbss×Bbss

Gametes of parent Bbss are: Bs and bs  as given that the genes are linked.

Bs, bs × Bb, bs

Offspring are = BBss, Bbss, Bbss, bbss

Black spotted (B_ss) = 3/4

muminat
<h2>Tropomyosin</h2>

Explanation:

This protein is most likely:  Tropomyosin.

Sacromere is the structural unit of myofibrils i.e. the fibres of the muscles.

Tropomyosin is the muscle protein that function in contraction of muscle filaments.They are arranged laterally along the myofilament. When the researcher is observing the sacromere, she is observing the muscle fibre.  So, the protein that lines the periphery along the thin filament is more likely to be tropomysin.
