Crossing two yellow mice results in 2/3 yellow offspring and 1/3 nonyellow offspring. What percentage of offspring would you expect to be nonyellow if you crossed two nonyellow mice?
a. 25%
b. 33%
c. 66%
d. 75%
e. 100%
The answer is e. 100%. If crossing two yellow mice results in 2/3 yellow offspring and 1/3 nonyellow offspring.
If crossing two yellow mice results in 2/3 yellow offspring and 1/3 nonyellow offspring,this means that both yellow mice have the genotype Yy (with Y being the dominant yellow allele and y being the recessive nonyellow allele). When crossing two nonyellow mice, both would have the genotype yy (with both alleles being the recessive nonyellow allele). When crossing two nonyellow mice, both would have the genotype yy (with both alleles being the recessive nonyellow allele). Therefore, all of their offspring would inherit one y allele from each parent, resulting in all nonyellow offspring. So the percentage of nonyellow offspring would be 100%.

Considering your knowledge of codons and how they code for an amino acid, would all substitu- tion mutations lead to a change in the amino acid sequence? Explain your reasoning.
Not all substitution mutation lead to a change in the amino acid sequence. Substitution mutations occur when a nucleotide in the DNA sequence is replaced by another nucleotide.
Each amino acid in a protein is coded for by a sequence of three nucleotides called a codon. Some substitution mutations do not change the codon or the amino acid that it codes for and are called synonymous or silent mutations. The codons GGA, GGC, GGG, and GGU all code for the amino acid glycine.
If a substitution mutation occurs in the third position of the codon, it may not change the amino acid that is coded for. A mutation from GGU to GGC still codes for glycine and is therefore a silent mutation. If the mutation occurs in the first or second position of the codon, it is likely to result in a different amino acid being coded for and is therefore a missense mutation.

Cytokinesis often, but not always, accompanies _____. Cytokinesis often, but not always, accompanies _____.telophase prometaphase anaphase metaphase interphase
Option a is correct. Cytokinesis often, but not always, accompanies telophase which is the final stage of mitosis.
After nuclear division during mitosis or meiosis, eukaryotic cells divide their cytoplasm to create two daughter cells. This process is known as cytokinesis.
The nuclear envelope reforms around the two sets of chromosomes, which have been moved to the cell's opposite poles, during telophase. Under a microscope, the chromosomes become less discernible when the spindle fibers separate and start to uncoil.
Actin and myosin filaments start to form a contractile ring around the cell at the same moment, squeezing it inward and eventually leading it to divide into two daughter cells. While cytokinesis frequently precedes telophase, it can also take place prior to or after nuclear division.

Cytokinesis, which is the division of cytoplasmic components into two daughter cells, often accompanies telophase, the last stage of mitosis. However, the process of cytokinesis and its occurrence can vary according to the cell type and species.
Explanation:Cytokinesis often, but not always, accompanies telophase. Cytokinesis, sometimes referred to as 'cell motion,' is typically viewed as a subsequent stage of mitosis. It facilitates the complete physical separation of cytoplasmic components into two daughter cells following mitosis.
Mitosis consists of several phases: prophase, prometaphase, metaphase, anaphase, and telophase. Cytokinesis often begins during the late anaphase and carries on to telophase. However, the occurrence of cytokinesis can vary based on the species and the type of the cell.
In animal cells, cytokinesis typically results in the division of cell contents via a cleavage furrow, which is a constriction of the actin ring, leading to cytoplasmic division.
