In tomato plants, the germ cells are in the flowers. The yellow (Y) gene controls flower color, such that Y_ plants have yellow flowers and yy plants have white flowers. The red (R) gene controls fruit color, such that R_ have red tomatoes and rr plants have yellow tomatoes. The R and Y genes are 15 maps unit from each other on chromosome 2. A botanist sets up a parental cross between a true breeding yellow flowered plant with red tomatoes and a plant that is true breeding, double-recessive for the Y and R genes. What are the expected frequencies of the recombinant and parental gamete genotypes produced by the F1 plants? Choose all correct answers.

a. Each parental gamete genotype will be produced 50% of the time.

b. each recombinant gamete genotype will be produced 7.5% of the time.

c. the total percentage of gametes with parental genotypes will be 100%.

d. the total percentage of gametes with recombinant genotypes will be 50%.

e. each parental gamete genotype will be produced 42.5% of the time.

f. the total percentage of gametes with recombinant genotypes will be 15%.

g. each recombinant gamete genotype will be produced 25% of the time.

the total percentage of gametes with parental genotypes will be 85%.

Even though the ostrich is a flightless bird, ostriches still possess wings that stretch approximately two meters across when fully extended. scientists speculate that when dinosaurs became extinct, some of the birds that lived during that time became land dwellers since they were able to consume the food that the dinosaurs once ate. over time, these species grew larger and heavier. eventually, the ostrich species became too big to fly. the wings found on ostriches are known as a. analogous structures. b. homologous structures. c. vestigial structures. d. symmetrical structures.
