I've this big biology text book in front of me
so Im going to the glossary, randomly picking a word, and writing the definition...so lets see who can guess the word!

Among the earliest plants to produce seedlike structures or seeds.

Is it pteridosperm ?

Definition of pteridosperm:-
""seed fern: an extinct seed-producing fernlike plant of the order Cycadofilicales"".

The question is ambiguous. Do you mean "earliest" in an historical or annual sense?

O.K. here is another random one

Type of photoautotrophic protistan; most are multicelled and aquatic; an abundance of phycobilins masks their chlorophyll.

guess guess!
I dont think I will give a clue on this one.

But only if you're using an English (US or UK) keyboard.  Don't do that with French or German keyboards.

As far as I understand the question, it is asking what you call a trait that is somewhere between what you inherited from your mother and what you inherited from your father (e.g. tall father, short mother, child somewhere mid height).

Don't ask me what it's called though.

OK, after a little hunting around on Wikipedia (is that cheating?), the word I have come up with is codominance or incomplete dominance.

http://en.wikipedia.org/wiki/Dominant_gene
quote:

Codominance/ Incomplete Dominance


In certain cases, a "blend" of genes will occur because neither of the two genes of a genotype are dominant over the other. As an example, in blood cells, the trait for blood type has three different alleles: type A, type B, or type i, with i being recessive. If a father passes a gamete with the allele of type A and the mother passes on type B, then codominance results, with the offspring being type AB since neither allele type dominates the other.
Incomplete dominance occurs when certain of the recessive gene appears within the phenotype of the organism, causing a blend in between both the dominant and recessive gene.



http://en.wikipedia.org/wiki/Incomplete_dominance
quote:

n genetics, dominance relationships control whether an offspring will inherit a characteristic from the father, the mother, or some blend of both. More technically, they control the ways genes interact to express themselves as phenotypes in a diploid or polyploid individual.
There are three kinds of dominance relationships:

  • Simple dominance

  • Incomplete dominance

  • Co-dominance




Incomplete dominance


In incomplete dominance, a heterozygous genotype creates an intermediate phenotype. In this case, both the dominant and recessive gene are expressed, creating a blended or combined phenotype. A cross of two intermediate phenotypes can result in the reappearance of either the parent phenotypes or the blended phenotypes.
The classic example of this is the colours of carnations.
---- R --- r
R -- RR -- rR
r -- Rr --- rr

R is the gene for red pigment. r is the gene for no pigment.
Thus, RR offspring make a lot of red pigment and appear red. rr offspring make no red pigment and appear white. Rr and rR offspring make a little bit of red pigment and therefore appear pink.
An example of incomplete dominance in humans is mordan, a trait that is exhibited when eye color alleles from the maternal and paternal chromosomes are blended. This usually occurs when one parent has green eyes and the other parent has brown eyes–the child will have dark blue eyes.

Co-dominance


In co-dominance, neither phenotype is dominant. Instead, the individual expresses BOTH phenotypes. The most important example is in Landsteiner blood types. The gene for blood types has three alleles: A, B, and i. i causes O type and is recessive to both A and B. When a person has both A and B, they have type AB blood.
Another example involves cattle. If a homozygous bull and homozygous cow mate (one being red and the other white), then the calves produced will be roan-colored, with a mix of red and white hairs.
Example Punnett square for a father with A and i, and a mother with B and i:

---- A --- i
B -- AB - B
i –- A --- O
Amongst the very few co-dominant genetic diseases in humans, one relatively common one is A1AD, in which the genotypes Pi00, PiZ0, PiZZ, and PiSZ all have their more-or-less characteristic clinical representations.

Stick around – you'll pick it up.

The few months I've been here, and had occasion to debate with all sorts of people about all sorts of things has taught me a lot.

Are you trying to make these too easy? [:)]

I assume you mean atrophy, although words like apoptosis or necrosis might have a related meaning, although more specific in nature.

PS. Don't expect me to understand the Spanish – now if that was Hungarian or German, then I might have a fighting chance (although I am not particularly fluent in either, but certainly better than my Spanish).

The word that seems closest is senescence.  To me, it seems more the study of ageing, although arguably ageing is the process of natural death.
