The right answer is 1/4.
Two carriers of the disease each have a chance in two to transmit their sick gene ie: 1/2 * 1/2 = 1/4
A genetic disease is said to be autosomal recessive when
The gene involved is carried by an autosome (non-sex chromosome, X or Y in XY system of sexual determination);
The associated phenotype of this trait is recessive (the presence of two identical alleles is essential for the character to be expressed).
One of the two alleles is transmitted by the male gamete, the other by the female gamete.
But being a carrier of the mutation does not necessarily mean being sick, the manifestations of a genetic disease depend on its penetrance and the variability of its expression.
Answer:
The correct answer is: a. directs somatic motor axons to four of the six extrinsic eye muscles and also transmits parasympathetic visceromotor impulses to pupillary constrictor muscle of the eye.
Explanation:
<u>The </u><u>oculomotor nerve </u><u>(III) is the third cranial nerve.</u> It provides motor innervation to four of the six extrinsic muscles of the eye and has also a parasympathetic component in charge of contracting the pupil when the environment is rich in light.
The cranial nerve that innervates the lateral rectus muscles of the eye is the abducens nerve (VI).
The cranial nerve that provides motor innervation to the superior oblique muscle of the eye is the trochlear nerve (IV).
Answer:
A. ponds are shallower than lakes
Explanation:
Ponds are not larger than lakes.
Pond water may move more than lakes in some situations, but it is not a defininte.
Lakes don't always have more vegetation than ponds.
DNA contains the information to makeproteins, which carry out all the functions and characteristics of living organisms. ... In DNA, each protein is encoded by a gene (a specific sequence of DNA nucleotides that specify how a single protein is to be made).
B. Because, Bacteria is a prokaryote on its own.
