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.
