3. a) A plant can have either tall (T) stems or short (t) stems. Two plants are crossed. One has the genotypeTt and the other has the genotype Tt. Fill in the Punnett square below for this cross. (1

2. How will the alleles for these traits assort into the gametes that each parent might produce? (Hint: For a reminder on how alleles sort independently into gametes, refer to the illustration in Part 2, Question 2, in the Student Guide.)

Which dominant means that it will show up in the offspring if one of the parents supplies that

A) Their F1 offspring were 97 wild type quahaug flies. What is the genotype of these F1 flies??

The total number of Pago Fuagans that are carriers of the (g) allele and phenotypically normal =

Read the background information in the Question Column under “How can Punnett Squares help predict the traits of offspring?”

3. When Mendel transferred pollen from one pea plant to another, he was ___ the plants.

---If given traits and parents, be able to use a Punnett square or patterns to predict the probability of offspring for a given cross and express it as a fraction, percent, or ratio.---

This Punnet Square represents the F1 offspring breeding with each other to create more offspring. This second set of offspring is the F2 generation. If both parents are heterozygous dominant, then the offspring expected would be: 50% heterozygous dominant, 25% homozygous dominant and 25% homozygous recessive.

Based on my survey I feel that free earlobes, no hair present between second and third knuckles, straight hair line, curly hair and no cleft chin are the most dominant trait because they had the highest percentage.

with a frequency of 25%, and crossover gametes between genes Y and Z are observed with a

The variables in this lab were different than the average science experiment. Instead of affecting the experiment to prompt different results, we just had F1 generation plants produce offspring so that we could study their specific traits. By looking at the variables, we can determine if they fit the Mendelian ratio and see if genes are linked on a chromosome.

You are also provided with a heterozygous female, and a homozygous recessive male for a genetic cross. In this particular female, all the dominant alleles are on one chromosome, and the recessive counterparts are on the other homologous chromosome. Due to a chromosomal condition, in the female no recombination occurs between the M and N loci. Normal recombination occurs between the L and M loci. Diagram this cross, and show the genotypes and frequencies of all offspring expected from this cross.

This table helps show all the possible genotypes from one set of parents. The table shows that the genotypes purple and starchy are dominant, and the genotypes yellow and sweet are recessive.(stallsmith)

The pairs of alternative traits examined segregated among the progeny of a particular cross, some individuals exhibiting one traits, some the other
