#Unit 8. Inheritance Biology
Consider the following diagrams, each being a different situation in which an entire gene is represented in a higher organism. In some cases, a point mutation exists (indicated by p). In other cases, a deletion has occurred (indicated by xxxxx), both of which render the gene nonfunctional

#Unit 8. Inheritance Biology
Maximum height of plant is 200 cm and minimum average height is 80cm. if plant height is controle by 5 pairs of polygene, which of the following plant exhibit average phenotype?
#Question id: 5424
#Unit 8. Inheritance Biology
Imagine that height in corn plants is determined by three loci. The baseline height is 100 cm. Every + allele adds 10cm to the plant’s potential height, every – allele subtracts 10 cm from the plant’s potential height. The shortest possible plant and the tallest possible plant are mated to form an F1, what is the height of the F1?

#Unit 8. Inheritance Biology
Two varieties of maize averaging 50 and 20 inches in height, respectively, are crossed. The F1 progeny is quite uniform averaging 35 inches in height. Out Of the 16 F2 plants, the 5 are 35 inches. What is the probable number of independent segregating polygenes involved in this trait?
