In guinea pig, rough coat i dominant (R) to mooth coat (r) and black coat (B) i dominant to white coat (b). A rough black guinea pig bred with a rough white one produce 29 rough black offpring, 31 rough white offpring, 11 mooth black and 9 mooth white. Give the genotype of the parent, punette quare
Answers
RrBb (rough, black) and Rrbb (rough, white) are the genotypes of the parents guinea pigs.
The parent genotype cannot have RR alleles for their coat because the smooth coat phenotype is present in the offspring. Similar to this, the rough, black parent is unable to have BB alleles in its genotype because doing so will prevent its offspring from having a white coat color. This can be understood with the help of the punnet square given in the answer. Therefore, the probability for each phenotype would be as follows:
rough black- 3/8 rough white- 3/8 smooth black- 1/8 smooth white- 1/8A dihybrid cross is made up of two people who share two traits that are controlled by two different genes. The idea of a dihybrid cross was developed as a result of Gregor Mendel's observation of pea plants that were either round or wrinkled, yellow or green.

Answers
crossovers between these genes result in chromosomal exchange.
Linked genes move along at the same anaphase.
Genes that are near to one another on the same chromosome are linked and move through meiosis together. As a result, related genes do not assort separately.
The genes are positioned near together if the recombination frequency is low; however, if it is high, the genes are spread out.
Every trait is inherited independently of every other trait, according to Gregor Mendel's Law of Independent Assortment.

What is a karyotype?
A karyotype is a term used to refer to the complete set of an individual's chromosomes. It refers to the total number of chromosomes found in each individual cell. The karyotype is the individual's chromosomic dotation.
Each species has its own karyotype because the number of chromosomes per species might vary. For instance,
The karyotype of human beings is composed of 23 pairs of chromosomes or 46 chromosomes. The karyotype of Drosophila melanogaster is composed of 4 pairs of chromosomes.
Whenever there is affection, karyotypes might vary among individuals of the same species. For example, people affected by Down syndrome have 47 chromosomes in pair 21 because of a chromosomic segregation failure during meiosis.
The karyotype concept can also be used to refer to clinical diagnosis.
When looking at the exposed karyotype, we can say that,
A) The individual is a male because there is an X and a Y chromosome.
B) This is a human being's karyotype but does not belong to a sperm cell.

This karyotype represents a diploid cell with 44 autosomes and 2 sexual chromosomes aligned and paired with their homologous chromosome.

Fertilizer runoff leads to excess nutrient and promotes algal blooms. The major nutrient responsible for algal bloom is nitrogen and phosphorus.
Nutrient pollution, or an excess of the vital plant nutrients phosphorous and nitrogen, is what can cause blooms. These substances enter rivers through a variety of pathways, including point sources (such as industrial and wastewater treatment plant discharges), nonpoint sources (such as septic tanks and stormwater runoff from cities, farms, and residential areas), and nutrient-rich rainfall. The ideal triad of temperature, sunlight, and low flow can cause an algal bloom when the levels of nitrogen and phosphorus in a body of water rise. Although nitrogen and phosphorus are present in nature and are vital plant nutrients, an excess of these nutrients can lead to serious ecological imbalances in a water body, with blooms as one symptom.

Answers
The total energy exchanged during photosynthesis for this environment is 290,000 cal/m2/yr.
The term "net primary productivity" refers to the amount of energy retained by an environment's biomass when energy is released for metabolism and maintenance. Net primary productivity, as opposed to gross primary productivity, refers to the total energy input into the ecosystem before taking into account energy loss.
Net primary productivity (NPP) is calculated mathematically as Gross Primary Productivity (GPP) - Respiration.
NPP = 175,000 cal/m2/yr for the pine forest, and respiration = 115,000 cal/m2/yr, hence GPP = 175,000 + 115,000 = 290,000 cal/m2/yr.

Calculating with the definition of speed, it will take the motorcycle 0.2 h (12 minutes) to travel a distance of 8 km.
First, you have to know that speed is a measurement quantity that explains the relationship between the distance travelled by an motorcycle in the given case. Thus the speed is linked with the change of position of motorcycle in distance within a definite amount of time.
The speed can be calculated using the following formula;
In the given case;
speed= 40
distance travelled= 8 km

Answers
If a heterozygous round plant is crossed with a homozygous round plant then from the 2400 plants produced, 1200 will be pure round plants. Pure round plants are homozygous for the trait.
What are genes?Genes are the units of hereditary information. Genes carry the genetic information about the various characteristics in an organism in the form of sequences of amino acids and nucleotides.
Mendel described in his laws that genes present on DNA carry the genetic information which is transferred to the offspring during reproduction. Each gene has a pair of alleles which are responsible for contrasting character such as in case of plant height, two alleles are present from which one is dominant which is tall and the other one if short or dwarf which is recessive.
The number of plants which are pure red = 1/2 of the total plants produced or 50% of the total F1 progeny.
Thus, number of pure round plants = 1/2 × 2400
Number of pure round plants = 1200
