The final product is<span> four daughter haploid cells. </span>
<span>It's because the genome has undergone mutation which means the foetus has a post anal tail and when the fetus matures the genome triggers absorption in development to remove unnecessary components by disintegrating the unnecessary cells (webbing, tail, etc). When this is not removed it is because the genome did not send the signal for absorption.</span>
The answer is <span>a.1/8</span>
<span>This is
an example of Mendelian dihybrid cross (a cross between two different traits).
If:
Y - (dominant) allele for the first trait
r - (recessive) allele for the first trait
S - (dominant) allele for the second trait
s - (recessive) allele for for the second trait
</span>The cross will be like:
Parents: YyTt x
YyTt
As shown in image, there will be in total 16 different genotypes. Two of them are YyTT genotypes. So the probability that the offspring will show YyTT genotype is 2 of 16:
= 2/16 = 1/8
1. is the second answer I believe and 2. is the first answer
I hope this helps
