The chance of the offsprings with stripe on head is 50%.
Option A.
<h3><u>Explanation:</u></h3>
Here according to the figures, the male is the brown one which has no stripe on his head as mentioned, and the female is the pink one who has a stripe on her head. The gene for the head stripe is denoted by H.
So the genotype of the father which is given as Hh. He is heterozygous.
The genotype of the mother should be hh as she has stripe and she must be homozygous recessive to have it.
So the gametes from father is H and h. Whereas the gametes from mother is only h.
So the genotype of the offsprings are Hh and hh as 50% each.
So the probability of the offspring being striped head is 50%.
All medical research is carefully planned, and this includes medical
research with animals. Experts who review a scientist’s proposed
experiment involving animals weigh several considerations before
approving each study.
The most important thing is that the research must be relevant
to human or animal health. Studies need to protect the animals’
welfare. That means that only the fewest number of the most
appropriate species may be used. Under federal law, all animals
must be treated humanely and undergo the least distress possible
