5. Choose another trait and genotype, and make another Punnett square. ratio of genotypes: ratio of phenotypes: ояти Activity #3 on Albinism: DOOMED CORN. DOOMED CORN. Albinism occurs in many species of animals, and in plants. For the animals, the condition may be an inconvenience, but for the plants it can be a death sentence. Consider that the green pigment, chlorophyll, is necessary for plants to produce food by photosynthesis. Without chlorophyll, the plants soon starve to death, so a...

Punnett Square for Question #4 is a the top
Punnett Square Genotypic ratio: Phenotypic ratio: 5. Purple flowers (P) are completely dominant over white flowers (p). If a pea plant is heterozygous for purple flowers, can any of this plant's offspring have all purple flowers? Think about the different genotypes with which you can cross the hetero- zygous parent: homozygous dominant, heterozygous, and homozygous recessive. Use three Punnett squares to show your work for each possible phenotype. Heterozygous purple pea...

Human Mendelian Traits Mendelian Traits are those traits which follow Mendel's rules of only 2 possible versions of a gene(1 dominant, 1 recessive). There are only a few examples of this in humans. 1. Circle the heterozygous dominant genotypes: AA Aa aa YyYY W Re RR 2. Circle the homozygous recessive genotypes: AA Aa aa YyYY V ir Rr RR 3. Use the chart below to determine your phenotype (observable characteristic) and possible genotype(s) (a pair or pairs of alleles)....
