Answer:why donI not see the punnet square?????
genotype and phenotypes below
Explanation:
BbEe x BbEe
BBEE, BBEe, BbEE, BbEe
BBEe, BBee, BbEe, Bbee
BbEE, BbEe, bbEE, bbEe
BbEe, Bbee, bbEe, bbee
Phenotype
BE 9
Be 3
bE 3
be 1
There is no indication here that these genes are sex-linked, so phenotypes are as they are regardless of sex, i.e. (b)(e)XX and (b)(e)XY are the same
The right option is; A) gametes
Gametes are reproductive cells (male (sperm) or female (eggs)) that contain only half the usual number of chromosomes and unite during sexual reproduction to produce a new cell (zygote). The mutation for sickle cell anemia occurs in the woman’s gamete (eggs) and this type of mutation is known as germline mutation; a mutation that occur in the germ (reproductive) cells and can be passed on to an organism’s offspring.
One is a longer process than the other, also one is more toxic.
The production will most likely be halted by an inhibitor until the cell needs more to be produced
Answer: feed-back
When the product of a metabolic pathway accumulates, it may be able to slow down or turn off the pathway by inhibiting the activity of an enzyme that catalyzes an early step in the pathway. This is referred to as feed-back inhibition.
Explanation:
Feed-back inhibition is said to occur when the final product of a biochemical pathway signal the inactivation of the starting materials of the pathway.
For example: when pyruvate signal the inactivation of phosphofructokinase, the glycolytic pathway gets turned off.
