We have crossed true-breeding flies today. Wild type to mutant. Their phenotypes were wt and vg se. (Let’s not worry about males and females for now, just assume both genes are autosomal, which is normal in a Mendelian experiment). The results of a cross are phenotypes. I will be asking you for numbers or a ratio of phenotype numbers you expect to see in the offspring from this cross. To answer this, you’ll need to start with the genotypes of parents, then write their gametes, then write the offspring genotypes, then get the phenotypes based on them. Predict the results of this cross: In case both mutations are recessive; In case both mutations are dominant; In case vestigial wings are recessive and the sepia eyes are dominant.
To figure out the outcome of a cross, set up a Punnett square.a. Put the gametes of one parent at the top and those of theother on the left. To determine the allele(s) in each gamete fora given genotype, set up a systematic way to list all the possibilities. (Remember, each gamete has one allele of each gene.)Note that there are 2npossible types of gametes, where n is thenumber of gene loci that are heterozygous. For example, anindividual with genotype AaBbCc would produce 23 = 8 typesof gametes. Write the genotypes of the gametes in circlesabove the columns and to the left of the rows.b. Fill in the Punnett square as if each possible sperm werefertilizing each possible egg, making all of the possibleoffspring. In a cross of AaBbCc * AaBbCc, for example, thePunnett square would have 8 columns and 8 rows, so thereare 64 different offspring; you would know the genotype ofeach and thus the phenotype. Count genotypes and phenotypes to obtain the genotypic and phenotypic ratios. Becausethe…

What is the correct table in these two given? 1. Take two coins and assume that heads represent the dominantallele (A) and tails represents the recessive allele (a). The genotype for each coin isheterozygous (Aa).2. Assume that each coin represents one parent. When a single coin is flipped, one gameteis formed (through the process of meiosis). If the flipped coin is on heads, then thegamete has the dominant allele (A). When both coins are flipped simultaneously, therewill be two possible gametes that can combine through fertilization to form a zygote. Eachtime you flip both coins, you will record the “genotype” of the offspring.3. Flip the coins 100 times and record your results in the chart below
A male rabbit with genotype GgBb x with a female rabbit with genotype ggbb. The female only has one possible combination (gb) and her gametes are completed on the Punnett square below. To set up the Punnett square, use the “foil” method to determine the alleles present in the gametes. The image shown below will help you set up the male rabbit’s genotype at the top of the square.
