Answer:
i am researching the answer give me a minute
Explanation:
In drosophilia, the gene for eye color is located on the x chromosome.
The allele for dwarfism - D its dominant
Recessive allele -d
If the person has heterozygous alleles -Dd the person will have achrondroplastic dwarfism
However if the person if homozygous for the allele DD it’s Lethal and person can’t survive
If both parents are Dd
Dd X. Dd
Offspring DD Dd Dd dd
Probability of children who survive with the trait have the genotype Dd
Probability - 1/4 + 1/4
Probability of having surviving children with the trait -1/2 -0.5
Answer:
b. A transferase deficiency will result in an accumulation of the toxic metabolite galactosse 1-phosphate.
c. A galactokinase deficiency will cause an accumulation of galactose.
Explanation:
Transferase is an enzyme which is responsible for the breakdown of galactose which is a known milk sugar. Its deficiency causes the formation of toxic materials such as galactose-1-phosphate which comes from galactose, and galactitol. Galactokinase is also an enzyme which helps in the conversion of galactose into galactose 1-phosphate with the expenditure of ATP molecule, so its deficiency causes the deposition of galactose.
An e.coli cell without a functional laci gene is expected to always produce B-galactosidase. i found the answer to this question on a set of quizlet flash cards. i have provided the link below in case you would want to look at the flash cards for reference.
