How are new alleles created? Occasionally, DNA mutations occur in germ cells – cells destined to become eggs or sperm. In this case, the DNA mutation is copied into every new cell of the growing embryo following fertilisation. ... If the mutation affects a gene, it will result in a new version of that gene – a new allele.
When you do that the fish will die. That is because it will take too much water in it and die from it, or rather, the fish's cells will take too much water in.
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%.
I’m not 100% sure but I brelieve the correct answer is 30 due to the hurricane being surrounded by land and no water for it to gain size, hence it weakening itself
