Script Exer 3c

The document outlines the steps to breed pigeons with specific phenotypes, detailing the creation of males with particular alleles and the use of Punnett squares to calculate the probabilities of desired offspring traits. It emphasizes the importance of allele interactions and epistasis in evolution, suggesting that these genetic factors influence species divergence and reproductive strategies. The probabilities for achieving specific phenotypes, such as female brown and check or female dilute and brown, are calculated as 1 out of 64 and 1 out of 16, respectively.

S5 To get the immediate parent of the given

goal phenotype on Lvl 16, Female, Brown


and check. First we need to create a male
with no spread allele, and at least one
wing pattern allele that is
recessive to ‘t-check’, which is in our case,
we chose bar and barless alleles. After
that, create a male with at least one ‘no
spread’ allele and one ‘check’ allele.
Lastly, breed the produced male pigeon
with the correct sex chromosomes and
alleles on the remaining pigeons to get
the required output.
S6 Next, in solving the probability of the
offspring, create a Punnett square on
each observed phenotype and predict the
possible genotype combination by
relating what is more dominant or
recessive than the other trait, then
indicate the ratios of what phenotype is
expressed. So for our offspring, we need
the ratio of female, checked, and not
spread allele. Multiply the resulting
phenotype ratios needed to get the
probability of the goal phenotype to
occur. So for our answer, the probability
of female, brown and check is 1 out of 64
or 0.015625.
S9 On the bonus level, to arrive at the goal
offspring phenotype, first, we need to
Create a male with at least one ‘dilute’
allele, second, is Create a male with at
least one ‘dilute’ and ‘brown’ allele .And
for the last step, Breed the resulting male
to the appropriate female pigeon and
choose the correct alleles and sex
chromosomes.
S 10 Now for the probability of the offspring,
create a Punnett square on each
observed phenotype and predict the
possible genotype combination by
relating what is more dominant or
recessive than the other trait, then
indicate the ratios of what phenotype is
expressed. So for our offspring, we need
the ratio of Female, Dilute and Brown.
Multiply the resulting phenotype ratios
needed to get the probability of the goal
phenotype to occur. So for our answer,
the probability of Female, Dilute and
Brown is 1 out of 16 or 0.0625
Sq 1. What is the evolutionary advantage Gene interactions or epistasis
of having allele or gene interactions? have a significant role in dictating
the evolutionary pathways of an
organism. There are several
influences epistasis can offer
including the genetic divergence of
the same species and evolution of
sexual reproduction and genetic
system structures (Phillips, 2008).
Epistasis is an inevitable result of
evolution, in which new traits are
created between species through
the effect of genetic masking by
suppression or combination of non-
allelic genes.
