Which statement best describes the relationship between an allele and a gene?

Mastering biology use the completed punnett square in part b to answer the questions below about the f2 generation. answer each

Sav [38]

1) The probability of F2 seed chosen at random will be yellow is the same as asking about the probability of forming a yellow seed in that generation. The answer is 3/4 (75%) because 1/4 = 25% GG is homozygous dominant and the rest 2/4 = 50% Gg are heterozygous.

2) In the F2 generation there are two genotypes that will breed true, which is homozygotic genotypes: GG and gg. But of these two, only one of them is yellow. The answer is 1/3 because from all the yellow seeds that resulted (GG, Gg and gG) only one has the genotype for true breeding.

3) The probability of taking out three seeds in which a least one is yellow can be calculated by subtracting the only probability that doesn't fit the criterion, which is taking out a green seed 3 times: $\frac{1}{4} * \frac{1}{4} * \frac{1}{4}$ = 1/64.
Then substract that to 1 $1- \frac{1}{64}$ = $\frac{63}{64}$

4) there are three possible groupings in which the green is taken once and the yellow seeds taken twice. The first possibility (follow the example) is the green being the first to come out, another possibility is being the second and the last possibility is being taken in the third time.
For example, Green yellow yellow- probability : 
 $\frac{1}{4} * \frac{3}{4} * \frac{3}{4}$ = 9/64

This is one possibily, but since there are 3, multiply it by 3 and you obtain the final answer:27/64.

Answer:

Robert Hooke is known for the first use of the word cell in the sense of a basic unit of organisms (describing the microscopic cavities in cork)

Plants are made of cells, Animals are made of cells, Cells produce other cells.

Eukaryotic have a nucleus meanwhile prokaryotic lacks of it.

Bacteria are prokaryotes

Cholesterol stabilize the cell membrane, less fluid at higher temp and less solid at lower temp.

Chromatin consists of the unravelled condensed structure of DNA for the purpose of packaging into the nucleus whereas chromosome consists of the highest condensed structure of the DNA doublehelix for the proper separation of the genetic material

Plant cell have cell wall, chloroplasts, plastids, and a central vacuole

Refers to going from regions of high concentration of some entity to regions of low concentration, and such movement generally occurs spontaneously,

Facilitated diffusion is the diffusion of molecules assisted by transport proteins

Passive transport no needs energy, move molecules trough phospholipid bilayer

Active transport needs energy, move molecules trough membranes

Endocytosis engulf substances and form vesicles (into the cell) (active transport)

Phagocytosis cell eats solid particles or big substances

Pinocytosis is the cell drinking, liquid substances

Exocytosis vesicles move through the plasma membrane, release the contents (outside the cell) (active transport)

Animal and plant cell organelles: nucleus, nuclear membrane, nucleoplasm, nucleolus, cillia, flagella, Rough Endoplasmic Reticulum, Smooth Endoplasmic Reticulum, Golgi apparatus, plasma membrane, vesicles, lysosomes, peroxisomes, centrioles, mitochondria, cytoplasm, cytosol, cytoskeleton, ribosomes, vacuoles, cell wall, chloroplasts.

Another name for a fertilized egg is zygote

Hope it helps :)
