Explanation:
During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, reads its DNA, and conducts other "normal" cell functions.b This phase was formerly called the resting phase.
1 c is the answer. <span>Energy is not created or destroyed; it can change form or can be transferred.
2d work is calculated as newton x </span>displacement so 60 x 4= 240 joules
They bond together creating compounds
Answer:
The dihybrid ratio we expect in the offspring is 9:7.
Explanation:
This is an example of complementary gene interaction, which is the non allelic interaction or genes, where the prominent genes at heterozygous loci may complement each other by complementing recessive alleles at the respective loci.
So in this case of complementary gene interaction, the individuals that are A-bb or aaB- or aabb will have the same set of observable features (phenotype) but only A-B- individuals will how the dominant phenotype.
Answer:
Testcrosses clarify linkage because each phenotypic class of progeny corresponds to each gamete type produced by the dihybrid parent.
Explanation:
- A test cross involves the crossing of an individual with another phenotypically recessive individual so as to determine the zygosity of the former by analyses of the proportions of offspring phenotypes.
- In order to determine linkage, the test cross shows that if the parentals are more than the recombinants, we can say that the two genes such as b and c are genetically linked and therefore, they must be on the same chromosome.
- Also, the test-crosses help to find out which alleles came from which parent.
- By setting up testcrosses in which one parent is homozygous for the recessive alleles of both genes,we can analyze the gene combinations received in the gametes from the other, doubly heterozygous parent.
