Evolution Jeopardy

Well this is a tough one. I am sorry you didn't include the problem with the length of the neck of the giraffe and the energy to pump the blood to the top of the neck to reach the brain and the series of regulators necessary to prevent the giraffe's head from exploding when he bent down to drink making the notion of a gradual change problamatic.And I think there are probably a couple 'right answers here', but you only want one.so I am going to say;What is d) he described the course of genetic mutations wrongly.

And I was wrong.Stupid french always mess things up.A

The correct response was A. The big giveaway for D being wrong is the time frame. The concept of genes and mutations wasn't there yet in Lamarck's time. Lamarck's idea that traits acquired in life can be passed on to offspring has made him the source of much ridicule, but it turns out he may have been a bit unfairly treated and some of his wrongest ideas exaggerated.

Well that should have been a no brainer for me there..I really didn't think that through well. 200 years ago they were till working off total faith for their theory.Okay let's go, the tougher ones are easier anyway.

Genetics 800The best way to complete the following sentence. A gene will be most successful at proliferating itself if it a) ensures the survival of its speciesb) makes it more likely that any individual with a copy of the gene reproducesc) makes it more likely that the individual with the gene survivesd) makes it more likely that its species protects itself against other species

Let's goWhat is c) makes it more likely that the individual with the gene survives? Alex

[crowTrobot 2]

a) he wrongly thought that acquired traits are heritable

there seems to be a lot of evidence supporting epigenetic imprinting of certain traits, so he may not have been totally wrong.

[BigDMcGee 3,352]

I think it's b

B is a better answer than C. If a gene can lead to greater reproduction of all copies of itself, regardless of which individual it is in, it has more opportunity to replicate. This is why, from a genetic perspective, individuals tend to expend a lot of resources on those who are closely related to them. Those kin are more likely to share copies of the same genes. A mother, for example, may sacrifice herself for a daughter who is the best chance at those genes proliferating. (see kin selection). Additionally, "survival" per se only indirectly increases the chance of a gene being replicated, insofar as surviving longer means greater chance of reproduction. The real currency is likelihood of reproduction, not survival. Balloon Guy: -1800

that big head is actually good for something.

Then why aren't there more hot women in the world?If a gene can think about it's sex life, wouldn't it first have to survive?A strong individual has a better chance to reproduce than one with a broken roof and a bad job.

[brvheart 1,752]

Did you guys see the new Hubble picture?

[vbnautilus 48]

Then why aren't there more hot women in the world?

There are hot women in the world precisely because those genes which make women attractive to men are more likely to get duplicated. But remember, variation is a key ingredient for natural selection.

If a gene can think about it's sex life, wouldn't it first have to survive?

Genes don't think about anything. It's just a principle that those genes which succeed in replicating themselves will become more adundant (its almost a tautology). They can do this best by conferring traits that lead to their duplication in any host. Those that do this will therefore become more abundant.

A strong individual has a better chance to reproduce than one with a broken roof and a bad job.

Depends. And .... wha?

[Sal Paradise 57]

A strong individual has a better chance to reproduce than one with a broken roof and a bad job.

damn.

[BigDMcGee 3,352]

A strong individual has a better chance to reproduce than one with a broken roof and a bad job.

I'm not sure if you're familiar with the demographics of america and the world, but I would guess someone with a broken roof and bad job would be much likelier to have more kids than a "strong individual".

Haha.. I was going to link the guy who did that video about the chick where he lifted hay bales, climbed mountains, rolled tires etc and then a link to the movie Idiocracy but I think you can appreciate the references without me needing to google all day.

[Balloon guy 158]

darn.

You know I am one of your cheerleaders for your life.

just like in the opening to idiocracy?

That was the best video pretty much ever.

Welcome back, folks! Picking up where we left off, with the final question in the category of Genetics. Genetics: 1000This is a chart showing the pedigree of family, some of whom are born with a debilitating brain disease that destroys the frontal lobes and makes them prone to religious belief. Women are represented by circles and men by squares. A darkened shape means that person has the disease, while a white shape means they don't have it. The most likely pattern of inheritance in this pedigree. (from the following choices:)A. MitochondrialB. X-linked dominantC. X-linked recessiveD. Autosomal recessiveE. Autosomal dominant

What is C. X-linked recessive?

What is C. X-linked recessive?

Sorry, that is incorrect. The correct response was "What is A. mitochondrial?"If you look at this pedigree you will see that whenever the mother has the disease, all of her offspring always also have it. This is matrilineal inheritance; since mitochondria are inherited matrilineally -- mitochondria always come exclusively from the mother (remember Mitochondrial Eve?) -- this is the pattern you will see with mitochondrial inheritance. With X-linked recessive, the union between an unaffected father and an affected mother (on the far right) would not produce affected daughters, since the daughters would each get one X chromosome from their dad, whom we know doesn't have the disease on his X chromosome (if he did, he would be affected). So each daughter would have a good X and a bad X, and if the trait were recessive two bad X's would be needed to show the trait in females. Balloon Guy: -2800

[uncooper 1]

What is C. X-linked recessive?

I think if it were recessive, then it would occur in 0-25% of the offspring from a mother displaying the trait and a father who does not. Since it occurs in 100% of such offspring shown in the diagram, I reckon that sucker is dominant.edit: oops slow and wrong.

If it were x-linked and dominant, then the daughters of affected fathers would always have the disease, since they get one of their X's from him. (imo)
