Punnett square of down syndrome. Punnett squares are commonly used by genetics counselors to predict the odds of a couple passing on particular inherited traits. A punnett square is a diagram or cross that shows the outcome and results of a potential genetic cross. This time is to be spent in reading the Question Paper.
Student teams trade DNA strands and de-code the genetic sequences to determine the physical. All possible genotypes for the haploid female gametes are listed across the top. The square is a visual representation of what colors to.
Lets look at a Punnett square to see why. A breeder wants to set up a program to produce zebrafish with long fins. These disorders are carried on the X chromosome and can only be passed on to males through their moms.
An example of a characteristic determined by a genotype is the petal color in a pea plant. In this case the mom is a carrier of the sex-linked trait. Academiaedu is a platform for academics to share research papers.
The allele for smooth pods S is dominant over the allele for pinched pods s. Answers to this Paper must be written on the paper provided separately. Well see how having an extra chromosome can lead to Down Syndrome and also examine the.
It comes from the French pied de grue cranes foot because the branches and lines of a pedigree resemble a thin cranes leg with its branching toes. This situation can be explained more clearly using the Punnett square to determine the probability of the offspring acquiring a specific genotype. You will not be allowed to write during the first 15 minutes.
Cloning results in two organisms that are. The first variant is termed dominant and the second recessiveThis state of having two different variants of the same gene on each chromosome is originally caused by a mutation in one of the genes either.
