7. When a pea plant of genotype Aa Bb produces gametes whatproportion will be ab?
8. Hamsters are long haired if they have the genotype LL or Ll andthey are short haired if they have the genotype ll. A long hairedhamster is mated with a short haired hamster. Half of the offspringare long haired and half are short haired. This allows us toconclude that the long haired parent hamster is? D
9. In peas yellow seed (Y) is dominant over green seeds (y) andtall plant (T) is dominant over short plant (t) .Calculate theprobability of the genotypes and phenotypes. in the F2 generationof a dihybrid cross that begins when a dominant homozygote iscrossed with a recessive homozygote. You must show the all of theprobability calculations. D
10. In a fruit fly experiment, two gray-bodied fruit flies producemostly gray-bodied offspring, but some of the offspring have blackbodies. If there are 280 offspring, how many will you predict willhave grey bodies and how many will have black bodies? How many ofthe 280 offspring do you predict will be heterozygous? Show yourwork. D
11. In a dihybrid cross AaBb X AaBb what fraction of the offspringwould be D
i) homozygous for both recessive traits
ii) heterozygous for both traits
ii) homozygous for both traits
