ten-legged green caped crab. They fell in love and had a beautiful crab wedding. The Generation one crustacean body’s phenotype was a plastic cup while the genotype was BB. The legs’ phenotypes were pearly white pipe cleaners and the genotype was ff. The crustacean had deep blue pom poms for eyes and the genotype was Ii. For antennae‚ the crustacean had soft qtips and the genotypes were Kk. One of Joy’s structural adaptations were vibrant purple stripes to help the crab camouflage in the colorful

use the phenotype ratios to determine the percentage of offspring displaying each trait. Well for one once you have the phenotypes all done on your Punnet Square then you go through and see what ratio of the offspring got the traits of the parents. For mine were to create phenotypes with 50% from each so my ratios were 2:4. 2. Can the genotype for a gray-bodied fly be determined? Why or why not? Describe all of the possible genotypes for a fly with that phenotype. Yes the genotype of a gray-bodied

What would be the phenotype(s) of the F1 generation dragons? c. Write out the genotypes of the F1 dragons that will be used to breed and give rise to the F2 generation. d. What gametes can be produced by the F1’s? e. What will be the expected phenotypic ratios among the F2 offspring? 2. In

plants were homozygous and both parent pea plants had two identical alleles. The plants in F1 generation were all heterozygous with two different alleles‚ one from each parent. This part can be understood more clearly by looking at the genotypes instead of only the phenotype. Mendel also discovered that one trait is dominant over the other trait. However‚ the dominant allele does not alter the recessive allele in any way and both alleles can be passed on to the next generation unchanged. These experiments

bond makes the G/C pair stronger. 2. How does an organism’s genotype determine its phenotype? The genotype is the organisms’ hereditary information while the phenotype is how the organism displays its properties. Another way of saying this is that the gene contributes to a particular trait while the phenotype is the expression of that gene. The genotype plays a large role in determining the development of the phenotype but other factors also play into its development such as plasticity

Explain how Mendel’s particulate mechanism differed from the blending theory of inheritance. • Blending: parents genes mixed • Particulate: parents genes still retain identity\ The blending theory was that genetic material contributed by the two parents mixes in a manner analogous to the way blue and yellow make green

possessed mutation #644. It is a mutation in wing morphology that reduces wing size. A controlled cross was conducted between these two true-breeding mutant flies. Their progeny (F1) being heterozygous for both mutations displayed only wild type phenotypes. These two mutations in Drosophila are both believed to follow an autosomal recessive pattern of inheritance. Figure 1. Images Drosophila melanogaster with mutations.

dominant phenotype and one for the recessive phenotype. These two alleles comprise the gene pair. One member of the gene pair segregates into a gamete‚ thus each gamete only carries one member of the gene pair. Gametes unite at random and irrespective of the other gene pairs involved.(Carlson) The purpose of this lab is to teach students how traits of an organism can be predicted with a dihybrid cross using the recessive and dominant traits. Using a dihybrid cross given the phenotype and genotype of F1
