Somatic mutation is the type of mutation among the choices given in the question that <span>contribute to evolution. The correct option among all the options that are given in the question is the second option or the penultimate option. I hope that this is the answer that has actually come to your desired help.</span>
I believe the answer is Rhodophyta.
Classification of protists in one kingdom is difficult because protists more closely resmble members of other eukaryotic kingdoms than they do other protists. Rhodophyta orred algae are distinct eukaryotic lineage characterized by the accessory photosynthetic pigments phycoerythrin, phycocyanin and allophycocyanins arranged in phycobiliomes and the absene of flagella and centrioles.
Because it’s a 50 % chance
The answer is 0.47 or 47%.
Let's first distinguish some terms and their frequencies.
R - the dominant allele that causes red eyes
r - the recessive allele that causes green eyes
Since R is dominant over r, lizards with at least one dominant R allele will have red eyes. Therefore, the genotypes and the phenotypes are as following:
genotypes - phenotypes
RR - the lizards with red eyes
Rr - the lizards with red eyes
rr - the lizards with green eyes
Now, we will use some Hardy-Weinberg equations:
p + q = 1
p² + 2pq + q² = 1
where:
p - the frequency of dominant allele R
q - the frequency of recessive allele r
p² - the frequency of lizards with genotype RR
2pq - the frequency of lizards with genotype Rr
q² - the frequency of lizards with genotype <span>rr
</span>
We are interested in <span>the frequency p of the dominant R allele.
</span>So, we have the frequency (72%) of the lizards that have red eyes. However, lizards with genotypes RR and Rr will have red eyes. Since their frequencies are p² and 2pq, respectively, we have:
p² and 2pq = 72% = 72/100 = 0.72
Now, use this in the equation p² + 2pq + q² = 1:
0.72 + q² = 1
q² = 1 - 0.72 = 0.28
From here, we will calculate q and later p using the formula p + q = 1:
q² = 0.28
q = √0.28 = 0.53
p + q = 1
p + 0.53 = 1
p = 1 - 0.53
p = 0.47
