Chapter four section 1

Diffrent species have diffrent amounts of ? But some species have? For example which ones have 48 chromosoms?

Give me the ones we have to memorize

Chromosomes . The same number of chromosomes… potatoes chimpanzees and plum

Carot 18 garden pea 20 cat 32 human 46 chimpanzee 48 orangutan 48 horse 64 and dog 78

Sex chromosomes and autosomes

Sex chromosome we have 2 choses gender

Autosomel chromosome 44 body charastristics

Sex cell 23 Only in egg and sperm

Autosomel 46 all of the body chromosomes

Human and animal chromosomes are categorized either?Sex chromosomes. And they may also? The two sex chromosmes are? Autosomes?

Sex chrom or autosomes. Are chromosomes that determine the sex of an organism. Carry genes for other charastristics.

X and y XX for normal femals XY for standared males

The remaning chromosomes are autosomal chromosomes Two are sex cell and the remaining are autosomal chromosomes

Every cell reproduced from sexual reproduction has how many copies??Homologues chromosomes? For example?

2 copies of each autosome which the organism recieves one copy of each autosome from the parents those two copies are known as homolugues chromosomes

Are the same size and the same shape and carry the genes for the same traits

If one chromosome in the homolugues chromosome contains a gene for eye color so will the other pair of homolugues chromosome

Karyo type . Are made?

Which is the photmicrograph of chromosomes of a diving cell found in normal humans

From a sample of the patient by extracting the white blood cell are treated chemically to stimulate mitosis and to arrest mittosis in metaphase the chromosomes are photo graphed and arranged by shape and size into pairs

A karyo thpe picture has how many pairs?

22 pairs the other pair is the sex chromosomes in the cell

Diploid. Which is abriviated to?Which it has?It also have?E.x?

Hiploid e.x?They have half the number of chromosomes? Which means it has? It is abriviated to? When 2 1n combine they form? If the reproduction cells had 2n what would happen?

Cells that have two sets of chromosomes 2n. Two chromosomes in each homolugues pair. Two sex chromosomes humans

These cells contain one set of chromosomes sperm cells and egg cells. That are present in diploid cells One chromosome in a homolugues pair and only has one sex chromosomes 1n

Sperm ell and egg cells combine they form the first cell of a new organism which its a diploid cell 2n

Then the organism would have to many chromosomes and wont be functional

Chromosomes are categorized as either?

Homologous chromosomes consists of?

Diploid has?

Sex chrom or autosomes

One autosomechromosome from each parent

Full homologues pairs consists of 22pairs of autosome and one pair of sex chromosomes
