The chance that the child produced would have nail-patella syndrome from this mating is 1/8 (12.5%) and the chance that the child has alkaptonuria is zero (0%). It is a case of recessive phenotypes.
The answer is incomplete, but I have now included the Figure to answer it. The vertical lines indicate nail-patella syndrome, while horizontal lines indicate alkaptonuria.
Pedigree is a diagram showing the genealogical relationships in different individuals, which is usually used to represent the inheritance pattern of a given phenotype.
In this case, the nail-patella syndrome and alkaptonuria are recessive phenotypes, which means that individuals may be heterozygous carriers but they need to have both mutated alleles to express each condition.
In the pedigree, it is possible to observe that the individual IV5 expresses both syndromes (nail-patella syndrome and alkaptonuria), whereas there is a 1/8 chance that the individual IV2 is a carrier of the nail-patella syndrome.

Answer:
The answer is a)
Explanation:
Hope it is helpful for you ✌️
give at least two examples.
The kingdom that is protista is referred to as junk drawer because there are certain species which has no similar characteristics entirely to a particular kingdom. These species therefore are made an adjustment like a junk in the kingdom caller protista where a fungi, plant and many eukaryotic species gets to live.
Eukaryotic organisms are the organisms that are having the well defined organelles and their genetic material is not scattered.
Euglena is a species which is having a characteristics of both the plants and animals where the euglena is able to synthesise its food and on the other hand euglena is able to divide as well thus these characteristics make the species get an exemption from both the species.
On the other hand certain species as fungi are belonging to the kingdom of both plants and animals where the species get an exemption from following any kind of rules and regulations strictly belonging to one particular kind of kingdom.

Explanation:
These are Protists, they are considered the "Junk Drawer" because they arent Animals, Bacteria Plants, or Fungi.
They are Eukaryotes, and some examples are Forams, New Zealand Bull Kelp, and Sea Lettuce
Sally inoculated 10 test tubes containing fresh minimal media supplemented with tryptophan with cells from this colony and grew the 10 cultures until the cells were dividing exponentially. She then plated 0.1 mL of each culture onto separate plates containing minimal media.
No colonies grew on 3 of the 10 plates. Colonies grew on the remaining seven plates, with one plate containing about 100 colonies and the other plates each containing between 1 and 15 colonies. What type of mutation allowed colonies to grow on these seven plates?
a) spontaneous forward mutation
b) spontaneous reverse mutation
c) induced forward mutation
d) induced reverse mutation
Answer:
b) spontaneous reverse mutation
Explanation:
Spontaneous mutations are produced by natural biological processes, while induced mutations are produced by mutagenic agents that trigger nucleotide errors in the DNA sequence. In the first phase of the experiment, Sally generated an induced mutation by using 5-bromouracil. The resulting strain required a constant supply of tryptophan to grow.
A reverse mutation restores the wild-type phenotype modified by a forward mutation, thereby reversing the phenotypic alteration to its original state. In a second step of the experiment, the colonies grew without the supply of tryptophan, thereby evidencing that the mutation was reversed in the original colony.
Answer:
Chromosomes are replicated during interphase before mitosis begins.

Answer:
Interneuron
Explanation:
Interneuron is association neuron or connector neuron. Which is completely contained within CNS. Usually conveys messages between parts of the system. Dendrites, axons, may be long or short.

What is the cause of his symptoms. Explain the mechanism.
Answer:
The lower back pain and bilateral leg pain is due to over and intense physical activity which causes stretching of ligaments and muscles resulting in back and leg pain. Such pain can be managed by limited or by reducing physical activity. The dark color of urine is due to the presence of bile (bilirubin) in the urine. Here the patient has a past medical history of alcohol abuse. Excessive alcohol intake enhances gut permeability resulting in enhanced absorption of bacterial endotoxins. Excessive endotoxins in the liver cause damage of the kupffer cells in the liver, resulting in the release of bilirubin in the blood which ultimately passes through kidneys into the urine.
