In a dihybrid cross, a blue budgie is crossed with a white budgie creating only blue offspring because all the progeny will show genotype yyBb, option c is correct.
In a dihybrid cross, one character is dominant over the other and masks the other allele and in a dihybrid cross, it follows the law of independent assortments.
Blue offspring only, because If a bluebudgie is crossed with a white budgie, yyBB or yyBb × yybb. let us yyBb for blue budgie, so we have; yB, yb, yB, yb representing the gametes.
On the other hand, in white budgie yybb, we will have yb, yb, yb, yb representing the other gamets in the cross. if a dihybrid cross occurs among these results, all progeny in marks will be yyBb, showing that they are all Blue offspring only.
Therefore all the progeny will be blue, hence option c is correct.

Answer:
Blue offspring only
Explanation:
If A blue budgie is crossed with a white budgie.
i.e yyBB or yyBb × yybb
let use yyBb for blue budgie,so we have; yB, yb, yB, yb representing the columns on the horizontal rows of the punnet square.
on the other hand, in white budgie yybb, we will have yb, yb, yb, yb representing the rows on the vertical column of the punnet square.
if a dihybrid cross occurs among these representative, all progeny in the punnet square will be yyBb, showing that they are all Blue offspring only.
lighter and stronger than previous models that they can sell at a higher price.
Which statement describes how a risk would be factored into a cost-benefit
analysis?
A. The cost of the materials to make the frames would be added to
potential improvements in consumer safety.
B. A reduction in employee safety would be added to the increase in
sales of the bicycle frames.
C. The ecological damage of mining the materials would be
subtracted from the profits made by selling the bicycle frames.
D. The money spent manufacturing the frames would be subtracted
from the profits made by selling the bicycle frames.
Cost-benefit analysis has been defined as the approach used to evaluate the advantages and disadvantages of the choices. The ecological damages must be subtracted from selling profits. Thus, option C is correct.
Cost-benefit analysis has been defined as the estimation of the cost and the profits in economical terms. It allows the determination of the monetary benefit gained by the manufacturing, production, and selling of the products.
To manufacture the bicycle frame the monetary benefit can be estimated by subtracting ecological damages for material mining from the profits earned by selling the frame of the bicycle. It gives the idea of how much it cost and benefits the maker.
Therefore, option C. (profits - ecological damage) gives a cost-benefit analysis.

Answer:
yellow insects population will decline
Explanation:
In a lush green area , it is easy for green insects to hide themselves. Thus, yellow colored insects can be easily traced by the predator species. This will cause decrease in population of yellow insects with time, while the green insect population will keep on growing. Removal of yellow insects also makes more food available for green insects . Hence without any environmental restriction , the green insects population will flourish well.
Answer:
During a 30-year period, the yearly frequency of drought is 10%,
Explanation:
Mendel is one of the first scientists to demonstrate the inheritance of the alleles or genetic pattern of an organism. He is regarded as the Father of Genetics and also gave some laws to study the inheritance pattern.
The correct answer is:
Option C. Only two alleles can exist for a given gene
The statements in correspondence to genetics can be explained as:
1. The genes can exist in variousforms, such that genes can have two or more two alleles. Alleles are the variant form of the gene.
2. The gene position on the chromosome is known as a locus. The alleles of a gene will also be present at the same locus.
3. The genotype is defined as the genetic makeup of an organism, in which alleles are categorized as purebred or heterozygous.
4. The phenotypically similar organism can have different genotypes, such that a yellow flower can be coded by YY or Yy genotype.
Thus, the statement only two alleles exist for the gene is incorrect in terms of genetics.
