You have been given three plants: Two have solid black flowers, and one has grey flowers. You cross each black-flowered plant to the grey plant with the following results:
Parents: black #1 X grey F1: 87 solid black, 83 spotted black
Parents: black #2 X grey F1: all black
To try and make sense of these results, you intercross the solid black-flowered F1 plants from cross #2 with the following results in the F2:
132 black
35 spotted black
11 grey
What are the genotypes of the parents, F1 and F2 generations?
Answers
Answer:
The correct answer would be -
F1: #1 black flower plant = Aabb and aabb and #2 = AABB and aabb
F2 = AaBb and AaBb
Explanation:
In this cross, it is the case of the dominant epistasis type of inheritance pattern as Gene A masks the expression of gene B but expresses itself only in presence of b or B.
The ratio of the dihybrid cross change in such inheritance from 9: 3: 3: 1 ratio changes to 12: 3: 1.

What is your opinion on the use of stem cells, obtained from fertilized eggs or early stage embryos
Answers
USE OF STEM CELL:
The first attempts to turn mature cells back into pluripotent stem cells involved a process called cloning. In the cloning process, an egg is fertilized in the lab, and right after fertilization, the DNA is removed from the egg.These stem cells come from embryos that are three to five days old. These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body. This versatility allows embryonic stem cells to be used to regenerate or repair diseased tissue and organs.Despite the potential benefit of using human ES cells in the treatment of disease, their use remains controversial because of their derivation from early embryos.Learn more:

Which best describes independent assortment?
In metaphase 1, chromosomes from the mother and father line up on opposite sides of the cell.
In metaphase 1, chromosomes from the mother and father line up randomly along the middle of the cell.
Portions of each chromosome switch sections in the mother’s and father’s chromosomes.
Portions of each chromosome break off and reattach to the original chromosome.
Answers
Answer:
In metaphase 1, chromosomes from the mother and father line up randomly along the middle of the cell.
Explanation:
In diploid (2n) organisms, the homologous chromosomes are the two copies of each chromosome, where one of these homologs is the chromosome from the mother, while the second one is from the father. During metaphase I, the homologous pairs of chromosomes pair together at the middle of the cell. The law of independent assortment, also known as or Mendel's Second Law, states that homologous chromosomes line up in random orientations at the metaphase plate during this period (metaphase I).

Genetics Problem Solving Chapter 25
Answers
Answer:
See the answer below
Explanation:
1. Tt x Tt
TT Tt Tt tt
Assuming that T is dominant over t:
Genotype ratio = 1TT:2Tt:1tt
Phenotype ratio = 3:1
2. Rr x Rr
RR Rr Rr rr
Assuming that R is dominant over r:
Genotype ratio = 1RR:2Rr:1rr
Phenotype ratio = 3:1
3. Assuming that green (G) is dominant over the other color (g). Heterozygous green would be Gg
Gg x Gg
GG Gg Gg gg
Genotype ratio = 1GG:2Gg:1gg
Phenotype ratio = 3:1 (green ratio the other color)
4. Assuming that green (G) is dominant over the other color (g) as above:
homzygous green plant = GG; heterozygous green plant - Gg
GG x Gg
GG Gg GG Gg
Genotype ratio = 1GG:1Gg
Phenotype ratio = 100% green
5. Assuming that tall (T) is dominant over short (t)
Homzygous tall plant = TT
short plant = tt
TT x tt
Tt Tt Tt Tt
Genotype ratio = 100% Tt
Phenotype ratio = 100% tall

Which line of defense includes active immunity?
O first
O second
O third
O fourth
Answers
Answer:
The second line of defense.
Explanation:
In our bodies the second line of defense includes active immunity. It contains non-specific immune responses, but yet still contains specific responses for certain things such as inflammatory and fevers.
Third line of defense includes active immunity. The correct option is C.
What are lines of defense?The first line of defense consists of chemical and physical barriers that are constantly ready to defend the body against infection.
Your skin, tears, sputum, cilia, stomach acid, urine flow, 'friendly' bacteria, and white blood cells called neutrophils are examples of these.
The second line of defense assists administration in effectively managing risk and controls.
Organization develops multiple risk management and compliance functions to assist in the development and/or monitoring of first-line controls.
Immune cells that specifically target antigens are the third line of defense. B-cells and T-cells, all white blood cells, are immune cells that play a role in the third defense line.
Antibodies are produced by B-cells. T-cells aid in the identification of pathogenic cells and the destruction of those cells.
Thus, the correct option is C.

A woman who has blood type A positive has a daughter who is type O positive and a son who is type B negative. Rh-positive is a trait that shows simple dominance over Rh-negative. Which of the following is a possible phenotype for the father?
A) A negative
B) O negative
C) B positive
D) AB negative
Answers
Answer:
The correct answer is - C) B positive
Explanation:
In the given question is the man has B positive blood group with two offspring a girl with type O positive and a son who is type B negative. In ABO blood group A and B if present together they express in offspring if present together.
Here the difference in the Rh factor only as the blood group O has no antigen on its surface therefore the most possible phenotype for the father as he has son with B negative and a daughter with O positive.

What did scientists believe was contributing to the depletion of the ozone layer and why?
Answers
CFCs and other halogen-source chemicals in the stratosphere were discovered to deplete the ozone layer.
What is ozone layer depletion?
Ozone depletion is the steady lowering of the Earth's ozone layer in the high atmosphere, which is produced by the discharge of chemical compounds from industry and other human activities that contain gaseous chlorine or bromine.
The ozone layer acts as a buffer against the sun's potentially dangerous ultraviolet rays. The destruction of the ozone layer puts humans in direct contact with dangerous ultraviolet rays, which can lead to a variety of health problems including cancer, cataracts, skin illnesses, and a weakened immune system.
