What happens when a true-breeding plant self-pollinates

All of its offspring have the same traits as the parent

A plant with two dominant OR two recessive alleles is said to be

homozygous

Which one of the following statements is NOT true

genes are the only influence on traits

How are sex cells different from other human cells?

sex cells are haploid

Why do sex-linked disorders occur more often in males?

Males only have one X chromosone

Instructions for an inherited trait are called....

genes

This diagram is used to trace a trait throughout generation of a family.....

a pedigree

What is a feature that has different forms in a population?

characterisitc

When there is a codominance....

each allele has its own degree of influence

The Law of Independent Assortment describes the random arrangement of homologous chromosone pairs during....

Metaphase 1

Two forms of a gene, one from each parent, are called.....

alleles

What is it calledwhen cells are divided with half the number of chromomes?

Meiosis

Which is the name for the way cells divide in asexual reproduction?

Mitosis

When a plant fertilizes itself, it is called a(n)

self pollinating plant

Traits passing from parents to offspring is called....

heredity

Chromatin condesnses into choromosomes, and nuclear membrane disappears...

Prophase I

The nuclear membrane re-forms, and the cell divides, the paired chromosomes remain joined...

Telophase I

The chormatids pull apart and move to opposite ends of the cell....

Anaphase II

Dominant alleles are reflected in....

the phenotype

When neither dominant or reesive alleles are reflected upon the phenotype (a red and white flower which produce a pink flower)

Incomplete dominance

When both alleles are shown somehow in the phenotype

Co-dominance

When there are more than just 2 alleles that affect the offsprings trait (such as bloodtype)

Multiple alleles

How many chromosomes do gametes have?

they only have half the chromosomes (they are haploid, they need to be fertilized to become a diploid cell)

Mitosis....

has 4 stages; is gentically uniform; has diploid cells; asexual reproduction; makes 2 cells

Meosis...

has 8 stages; is genetically diverse; has haploid cells; sexual reproduction; makes 4 cells

The genetic "make up" of something can be called...

genotype

What is the chemical formula for photosynthesis?

photons + 6CO2 + 6H2O-->C6H12O6 + 6O2

What is the chemical formula for cellular respiration?

6O2 + C6H12O6--> 6H2O + 6CO2 + 36ATP

Why genetic recombination beneficial in meiosis and dangerous in mitosis?

Meiosis promotes genetic diversity and in mitosis it would cause cancer

how do they sex cells get a full set of chromosomes?

fertilization

The different forms of genes (dominant and recessive) are known as.....

alleles

Sex cells are made during ...

meiosis

chromosomes are copied, and then the nucleus divides twice

meiosis

cells having two sets of chromosomes

diploid
