Answer:
d. carries nerve impulses toward another neuron, a muscle fiber, or a gland cell
Explanation:
An axon is a fiber of the nerves that transmits nerve impulses( electrical signals) away from a cell body and towards another neuron, muscle fiber or gland cell.
We have two types of axons in the body.
a. Myelinated axons
b. Unmyelinated axons.
The difference between Myelinated axons and Unmyelinated axons is that the Myelinated axons has an external covering or insulation which is called the myelin sheath.
The myelinated axons are very numerous and mush faster than the unmyelinated axon.
Answer:
b
Explanation:
<em>Let the wild type trait, the silver-white, be represented by </em><em>A</em><em> allele and the mutant trait, the golden color, be represented by </em><em>a</em><em> allele.</em>
Heterozygous wild-type male fish would be Aa
Golden female fish would be aa
Aa x aa
Aa Aa aa aa
2/4 Aa = silver-white
2/4 aa = golden color
<em>Hence, the percent likelihood of golden offspring is </em><em>2/4 or 50%.</em>
The correct option is b.
Polygenic inheritance result in a continuum of phenotypes because the genes that are involved can be considered to be co-dominant traits that fall into discrete categories are called continuous traits false.
<h3>What is Polygenic Inheritance?</h3>
A single inherited phenotypic trait that is governed by two or more separate genes is referred to as polygenic inheritance, often referred to as quantitative inheritance.
In a system that is distinct from Mendelian Genetics, wherein monogenic features are determined by the various alleles of a single gene, polygenetic traits may exhibit a variety of potential phenotypes, determined by a number of different genes and the interactions between them.
In contrast to Mendelian genetics, when one allele completely dominates or hides another, features generated by polygenic inheritance are not only the result of dominance and recessively. Instead, polygenic features show incomplete dominance, resulting in a combination of the phenotypes seen in the parents in the offspring.
