Irene could be either XHXH or XHXh. We know for a fact that she inherited at leasst one XH from her father, but there's a 50/50 chance of her inheriting an XH or and Xh from her mother

The red-green color blindness is a recessive X-linked trait. The females are not affected unless both the X chromosomes have the affected allele. Mostly, the females are the carriers, and the males are affected as they have only one X chromosome. In the given pedigree, the father of Irene have the normal allele, while her mother is a carrier. However, Irene is neither a carrier nor affected. This means that she carries normal alleles on both X chromosomes. Hence, her allele combination is X^{H} X^{H} .

Arisa [49]

Answer:

See the answer below

Explanation:

Let the disorder be represented by the allele a.

Since the disease is an autosomal recessive one, affected individuals will have the genotype aa and normal individuals will have the genotype Aa or AA.

Since the four adults are carriers, their genotypes would be Aa.

                    Aa     x     Aa

Progeny:    AA    2Aa    aa

Probability of being affected = 1/4

Probability of being a carrier = 1/2

Probability of not being affected = 3/4

(a) The chance that the child second child of Mary and Frank will have alkaptonuria = 1/2

(b) The chance that  the third child of Sara and James will be free of the condition = 3/4

(c)

(d) If someone has no family history of the disorder, their genotype would be AA.

                 AA     x     aa

                        4 Aa

<em>The chance that a child with alkaptonuria will have an offspring with alkaptonuria if the child's mate has no family history </em>= 0

(e)

(f) <em>The chance that a child with alkaptonuria will have an offspring with alkaptonuria if the child's mate has no family history</em> = 0

If you increase the number of water molecules in the extracellular fluid, will the membrane move to the right or the left in the
Igoryamba

Answer:

The membrane will move to the left in view of the applied pressure.

Explanation:

The scenario described can be perfectly illustrated through understanding the concept of osmosis.

Osmosis can be defined as the movement of particules or molecules in a solvent from a region of lower concentration to a region of higher concentration, through a semi permeable membrane.

To put differently, the movement of water molecules is from a region of lower osmotic pressure to a higher one. And for osmosis to be achieved and water molecules evenly distributed, pressure built must be slow and steady to a state of high or equilibrium.

This often results to movement of membrane to the left as a response to the osmosis phenomenon. Increasing the number of water molecules in the extra cellular fluid will thus accelerate this process, increase the pressure built up, and thus generate ripples from a lower area to a higher one. Osmosis is thus gradual and steady.

RUDIKE [14]

Answer:

The traits were linked

Explanation:

Gregor Mendel often called the father of genetics was a priest as well as scientist. He conducted many science experiments and determined the law of independent assortment and segregation.  He did however noticed that there were some traits seen in the parents that were passed to the offspring in the same combination. These were termed "linked-traits" and were the first indications that genes may be linked.

Answer:

The first blank can be filled with tagging. One of the procedures for studying the movements, biology, and migration of animals is known as tagging of animals. Tagging is utilized to examine the long-range irregular and regular movements of animals and to identify their life-span. All kinds of mollusks, vertebrates, and insects can be tagged.  

The second blank can be filled with designate their area as a national park. Designation of the areas as a national park is one of the methods of conserving animals, like a tiger.
