A pea plant is heterozygous for both seed shape and seed color. S is the allele for the dominant, spherical shape characteristic; s is the allele for the recessive, dented shape characteristic. Y is the allele for the dominant, yellow color characteristic; y is the allele for the recessive, green color characteristic. Think about the gametes this parent plant will produce. List the alleles in each gamete.

Answers

Answer 1
Answer:

During gametes production, alleles randomly separate producing different combinations in daughter cells. The gametes in this example are YS, Ys, yS, ys.

How are gametes formed?

Gametes are formed during meiosis. Meiosis is a cell division process that produces gametes from germ cells. Through Meiosis, a diploid cell (2n) produces four haploid daughter cells (n).

According to the segregation principle, alleles separate independently during gametes formation.

In anaphase I, homologous chromosomes separate, and each of them migrate to the opposite poles of the cell carrying one of the alleles. This random event leads to different chromosomal combinations in the daughter cells.

Now, let us analyze the problem,

Plant ⇒ heter0zyg0us for both seed shape and seed color ⇒ SsYy

  • S is the dominant allele and codes for spherical shape
  • s is teh recessive allele and codes for dented shape
  • Y is the dominant allele and codes for yellow
  • y is the recessive allele and codes for green

Gametes) YS, Ys, yS, ys.

Answer 2
Answer:

So, you would make a punnet square. You would put the capital S and lowercase s on the top of it and then the capital Y and lowercase y on the side. Then you should have SY, sY, Sy, and sy as your outcomes.

A farmer measures the soil depth below which the soil is saturated with water. His first measurement shows the saturation level at 1.2 inches below the surface. A week later, his second measurement shows that the saturation level has dropped another 0.4 inches.

Answers

Explanation:

When a farmer measures the depth of the soil to measure the saturation point of water in the soil and found that after 1.2 inches the soil is wet but after a week the saturated soil is found at 1.6 inches. There could be many reasons for this:

1. The crops could have utilized the water present in the topsoil.

2. The water has been evaporated from the soil due to farming practices if performed in that week.

3. The water could have percolated down as the soil could be highly porous.

4. The saturation of water depends on the physicochemical factors of soil also.

A six-carbon sugar is an example of a ______ that can join with other molecules to form a _____ such as starch or cellulose

Answers

A six-carbon sugar is an example of a monomer that can join with other molecules to form a polymer such as starch of cellulose. 

The right answer for the first gap is monomer.

The right answer for the second gap is polymer.

The polymer is a large molecule consisting of basic units called monomers (or monomer units) connected by covalent bonds.

A monomer is a compound of simple molecules that can react with other monomers to give a polymer.

Which of Mendel's laws or principles explains that traits are passed from parents to offspring individually instead of as pairs, groups, or sets?A. The Principle Dominance
B. the law of independent assortment
C. the law of segregation
D. the principle of genetics

Answers

The law of segregation is the Mendel’s laws or principles explain that traits are passed from parents to offspring individually instead of as pairs, groups or sets. So the correct option is option “C” as far as the given question is concerned. This is a law or principle which states that during the formation of gametes, two copies of each heredity factors separate out so that the new offspring can get one factor of both the parents. This law was the first law in this direction.


Answer:

Pathogens can be transmitted through contact with surfaces like doorknobs and countertops.a. True
b. False

Answers

The answer is a. True.

Some pathogens can be transmitted through direct contact with infected person, and some pathogens can be spread through contact with surfaces like doorknobs and countertops. For example, an infected person can touch these surfaces and leave behind pathogens. When an uninfected person touches the surfaces and then touches its skin, the pathogens are transmitted to that person. Staphylococci are the commonly transmitted this way.
