Organized representation of the chromosomes within a cell.A karyotype is a(n) __________.homologsDuring sexual reproduction, each parent contributes one set of chromosomes. Members of a pair of chromosomes (one from each parent) are called __________.The chromosomes in some cells will look normal (highly compacted) but in other cells distinct chromosomes will be hard to identify.You are performing a karyotype for the first time and you forget to add the colchicine. How do you predict this will affect your karyotype?sister chromatidsWhich of the following would contain genetic material that is 100% identical?56 (14 chromosomes * 4 chromatids (per homolog pair) = 56)You are studying a diploid organism that has 14 pairs of chromosomes. How many chromatids would this cell have in G2 phase?14You are studying a diploid organism that has 14 pairs of chromosomes. How many chromatids will a gamete from this organism have?28 (14 chromosomes * 2 chromatids) = 28)You are studying a diploid organism that has 14 pairs of chromosomes. How many chromatids will a cell from this organism have in metaphase of meiosis II?S-phaseDuring this phase of the cell cycle, the sister chromatids are formed:locusThe location of a gene on a chromosome is called its _____________.anaphaseDuring this phase of the cell cycle sister chromatids separate and head towards opposite poles of the cellmetaphaseDuring this phase of the cell cycle the chromosomes line up in the center of the cell:anaphaseDuring this phase of the cell cycle the separated sister chromatids are considered independent chromosomes:diploid, haploidIn animals, somatic cells are ________ and germ cells are __________.provide a link between homologous chromosomes in meiosis.The general purpose of the synaptonemal complex is to __________.4A bivalent contains how many chromatids?chiasmaThe physical structure that is formed when two chromatids cross over is called a(n) _______.2^5If an organism has five pairs of chromosomes, how many chromosomal combinations are possible at metaphase I of meiosis?4 haploid cellsThe end result of meiosis in animals is ______.alligatorsIn a species of turtles you are studying, you find that when eggs are incubated at a low temperature, the hatched turtle will be male. Eggs incubated at a high temperature yield females, and intermediate temperatures lead to both male and female offpsring. This mode of sex determination is most similar to that inHaplo-diploidA male produced from an unfertilized haploid egg is an example of what type of sex determination system?X-linked inheritanceIf an allele is inherited on the X chromosome, but not the Y, it is said to be an example of ________.An equal number of TP and Tp gametesYou are studying a new species of plant similar to Mendel's pea plants. You are specifically interested in two genes that are located on two different chromosomes. In this plant, the gene for height has two alleles, T (tall) and t (short). The gene for leaf color has two alleles P (purple) and p (pink). What meiotic products do you expect from diploid cells that are homozyous for the tall allele and heterozygous for the purple allele?X^w+Y and X^w+X^wYou are performing a fruit fly cross similar to those that Morgan performed. Unfortunately, you forgot to write down the parents of your cross. You count the progeny, and find you have 40 red-eyed males, 80 red-eyed females, and 40 white-eyed males. Assuming that all genotypes from this cross should have equal survival rates, what are the genotypes of the parent flies?34; 17; 17<span>A dipoid organism that you are studying has 17 pairs of chromosomes. How many total chromosomes are found in a somatic cell from this organism? A sperm cell? An egg cell?</span>
<span>The most expectant evolutionary feature would be longer necks. This will enable the tortoises to reach the higher grass. This <span>would occur through natural selection that would favor the extreme traits (alleles of long neck) of long necks in the population.</span></span>
The folds contain ribosomes attached to the membrane. The more the folds the more the surface area to which more ribosomes can attach. The ribosomes are organelles responsible for the manufacture of protein in cells. Thereafter, the proteins are properly folded by the mediation of chaperones in the lumen of the RER.
Digested food means that the food complex is cut into a smaller molecule that can be absorbed into the body. To digest food, the gastrointestinal tract will release many kinds of enzyme to make the chemical reaction happen. When there are a deficiency or dysfunction of the enzyme then the molecule won't be digested and can't be absorbed.
