Default science help

hey guys im trying to do good in science, i have a word bank of , kind of alot but if u can help me with some of the question that you might know off the top of your head that will be great otherwise no need.

Phenotype, f1 generation, heredity, dominant , recessive, homozygous, monohybrid,heterozygous, genetics, punnett square, dihybrid, genotype, carrier, codominance, testcross, incomplete dominance, traits, polygenic inheritance,multiple alleles, law of independent assortment, law of segregation

ok
This chart,__1______,shows possible combination of genes among offspring in a cross.

When i ask you for the descriptive word of an organisms appearance, im asking for its__2___. traits is not it

The genetic make-up of an organism is called its___3__

The gene that masks over the expression of another is said to be----

________4_organisms produce others exactly like them each time they reproduce.

A genetic cross that involves one pair of contrasting traits is called a __5_cross

A___6___- is when you cross an unknown genotype with a homozygous recessive individual.

A __7__________, or heterozygous individual, appears the same phenotypically as one that is homozygous dominant.

This type of inheritance is controlled by two or more genes:_8__-think it is multiple alleles but not sure

In this type of inheritance heterozygous individuals have a different phenotype than either of the homozygous option ___9____

This explains that the two alleles for a trait must separate during gamete formation.



These are the ones im struggling on, any help by some one who is good at science will be help.

If you can see this, you have WAY TOO much time on your hand. Or you're a mod going through my sig. But if you do, copy and past this in your sig.

1. Punnett Square
2. Phenotype
3. Genotype
3.5? Dominant
4. None of the answers work, some kind of asexual reproduction
5. Heterozygous
6. Test Cross
7. Carrier
8. You're right
9. could be codominance, not really sure
10. Law of segregation

um, these questions really aren't worded very well...
Oh, and someone should check my work
