In pigs, the allele for a wavy, rough coat (R) is dominant to the allele for a soft, fine coat (r). A rough coat boar and a soft coat sow mate. They produce several litters, 50% are rough coat and 50% are smooth coat. What were the genotypes of the parents?

Answers

Answer 1
Answer: 1. Do a pun-net square.
R r
r
r
2. The offspring would be Rr, rr, Rr, rr
3. 2 of them are heterozygous(Rr),which means they would be most likely rough coats
4. Two of them are homozygous for short hair (rr) which means they are going to be soft hair.
5. Your answer is
Rr, rr
Answer 2
Answer:

Answer:

Genotype of  rough coat boar - Rr

Genotype of soft coat sow mate - rr

Explanation:

Rough coat boar must be heterozygous with one dominant allele (R ) and one recessive allele (r )

Genotype of rough coat boar - Rr

Genotype of soft coat sow mate – rr

Now if these two parents are crossed , the offspring produced are represented in the punnet square below –  

R r

r Rr rr

r Rr rr

Thus, 50 % of the offspring’s have rough coat (Rr) and 50 % of the offspring’s have smooth coat.

For which method of determining population size is the population not aware of the sampler’s presence?

Answers

The answer is "Indirect observation".

In social research, there are two types of methods used; direct and indirect observation. In this case, since the population is not aware of the research it is clearly indirect observation. In this technique, it observed the effects of results compare to a direct observation which observes as it occurs.

Answer:

inert
an anion
a cation

Answers

Helium has an atomic number of two, so its outer energy level is full. Helium is considered inert. The correct option among all the options given in the question is the second option. It is actually non toxic in nature. Helium is also colorless, odorless and tasteless in nature. It is the first in the noble gas group of the periodic table.

Answer:

Why are sepals and petals referred to as "accessory parts" (of the plant)?

Answers

The calyx and corolla together compose the perianth. The sepals and petals are accessory parts or sterile appendages; though they protect the flower buds and attract pollinators, they aren't directly involved with sexual reproduction.

Meiosis and mitosis are both forms of cell division. However, the outcomes of these processes differ. Consider a diploid organism with two sexes. Select the reasons why meiosis typically produces genetic variation, whereas mitosis does not. Gametic chromosomes have a different combination of alleles than parental chromosomes as a result of independent assortment. Sister chromatids are not genetically identical as a result of crossing over during meiosis. 1n gametes produced in mitosis fuse to produce 2n cells in meiosis. Meiosis produces four genetically different haploid cells.

Answers

Answer:

Meiosis produces four genetically different haploid cells.

Gametic chromosomes have a different combination of alleles than parental chromosomes as a result of independent assortment

Explanation:

Meiosis and Mitosis are two types of cell division that occurs in living organisms. However, Mitosis produces daughter cells that are genetically identical to the parent cell while meiosis produces daughter cells that are genetically different from the parent cell. This accounts for the reason meiosis leads to genetic variation.

The production of genetically different cells by meiosis is as a result of the process of the random orientation of chromosomes during metaphase I of meiosis I. This process is called INDEPENDENT ASSORTMENT. However, crossing over occurs during prophase I of meiosis between non-sister chromatids of homologous chromosomes.

Final answer:

Mitosis and meiosis are processes of cell division. Mitosis results in two identical diploid cells, while meiosis creates four varied haploid cells, due to independent assortment and crossing over, which brings about genetic variation.

Explanation:

Both mitosis and meiosis are indeed processes of cell division that occur in living organisms. The fundamental difference between them is that mitosis produces two genetically identical diploid cells (cells with two complete sets of chromosomes), while meiosis results in four genetically varied haploid cells (cells with one complete set of chromosomes).

In mitosis, the division of the nucleus takes place, with each daughter cell receiving a full complement of chromosomes identical to those of the parent cell. On the other hand, in meiosis, two divisions occur, resulting in four daughter cells with half the number of chromosomes as the parent cell. These cells are further genetically unique, for two reasons: Independent assortment where the pairs of homologous chromosomes line up at the equator of the cell in a random manner, and crossing over, a process during which homologous chromosomes exchange portions of their DNA.
