What causes decrease in genetic variation?
Genetic variation decreases as a result of inbreeding, genetic drift, restricted gene flow, and small population sizes.
There aren't many variations among individuals in a species with low genetic diversity since there aren't many different gene alleles present. This would imply that there are less chances to adjust to environmental changes. Due to habitat degradation, low genetic diversity is frequently observed.
The difference in DNA between individuals or communities is known as genetic variation. Mutation and genetic recombination are two of the many processes that cause genetic variation. Genetic variety is primarily caused by mutations, although it is also influenced by other processes including genetic drift.

Explanation:
T or F? In the muscles of the limbs, the origin is usually the immobile muscle attachment
In the muscles of the limbs, the origin is usually the immobile muscle attachment. True
A skeletal muscle connects to bone (or other muscles or tissues) at two or more points. If the location is a bone that stays motionless during an activity, the connection is referred to as an origin. If the connection is on a bone that moves during the activity, it is referred to as an insertion.
Muscle tissue is classified into three categories in the muscular system: skeletal, cardiac, and smooth. The term "structural" refers to the fact that the body has a distinct structure. Skeletal muscle is responsible for the movement of bones and other structures. To pump blood, cardiac muscle contracts.

Any material of small granulometry, or up to five millimeters in size, is called sand. From that measure they are called stone. Stones are the result of the breakdown of rocks, just like sand, and in the crushing process it forms crushed stone.
How is sand formed?The formation of sand begins with the action of wind, rain, sun, tree roots and microorganisms that wear down the rocks present in various regions of the continent. Over the years, pieces of the stones break loose and, little by little, turn into small grains. This process is called erosion.
What kind of rock is sand?Sand is a detrital, mobile, permeable sedimentary rock that, according to the size of its grains, can be classified into coarse, medium and fine sand.

Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are through- merchandise and ATP is strength this is converted from the procedure. Cellular breathing is the procedure through which organisms use oxygen to interrupt down meals molecules to get chemical strength for mobile functions. Cellular breathing takes location withinside the cells of animals, plants, and fungi, and additionally in algae and different protists. Adenosine triphosphate (ATP) is the supply of strength to be used and garage on the mobile level.

In a certain plant, yellow leaves are dominant (Y) and red leaves are
recessive (y). A plant with genotype Yy and a plant with yy are crossed. If they have four offspring, how many would you predict would have red leaves? (Hint: Draw a Punnett square to help you determine the answer.)
A. 4
B. 3
C. 2.
D. 1
Answer: C
Explanation: When a plant with genotype yy and Yy are crossed there will be two yellow offsprings with genotype Yy(where yellow is dominating) and another two with yy(where leaves are completely red)
According to the information provided, yellow leaves (Y) are a dominant characteristic over red leaves (Y), which means that if the allele for yellow is paired with allele for red leaves as can be seen in Punnett square, it will hide the expression of red leaves. So, the correct option is D.
What is Punnett Square?The genotypes of a specific crossing or breeding experiment are predicted using the Punnett square, a square diagram. Biologists use the figure to calculate the likelihood that a child will have a specific genotype.
The information given indicates that yellow leaves (Y) have a dominant trait above red leaves (Y), that implies that if the alleles for yellow and red leaves are linked together as shown in Punnett square, this will conceal the manifestation of red leaves.
For red leaves, the genotype is yy, while the two potential genotypes for yellow leaves are YY and Yy. Parents have the genotypes Yy and Yy. When they are crossed, one of every four offspring that results will have red leaves.
Therefore, the correct option is D.

What is a 1:2 1 genotypic ratio?
The 1:2:1 genotypic ration dictates the law of are is homozygous dominant, heterozygous dominant and homozygous recessive.
A 1:2:1 genotypic ratio is a ratio of alleles that is found in a monohybrid cross. A monohybrid cross is a type of genetic cross in which only one trait is being studied. In a 1:2:1 ratio, the first number represents the homozygous dominant genotype, the second number represents the heterozygous genotype, and the third number represents the homozygous recessive genotype. This ratio can be found by using the Punnett square method.
This generally represents the genetics, of the first generation of the monohybrid cross made between the pea plant showing dominant and recessive traits. Such that dominant parent was homozygous dominant and recessive parent was homozygous recessive.

The following crossover frequencies for these genes were determined by & trihybrid test-cross experiments. Determine the sequence of genes A, B, and C on a chromosome. There are two correct answers: Crossover Frequency 12% Genes A&B A&C B&C 18%
The correct sequence of the genes A, B and C found on the same chromosome can be : B A C or C A B.
Genes are the part of DNA sequences that code for a certain protein responsible for a particular trait. These genes are present upon the chromosomes. Each chromatid can contain multiple genes on it.
According to the question, the crossover frequency between genes B and C is 18 % hence they are the farthest (18% = 18 centi-Morgan). And the frequency between genes A & B and A & C is 12% and 6% respectively. Therefore the distance of B and C is the sum of the remaining two. This determines the sequence could be B A C or C A B.
