Question 2 (1 point) ✓ Saved In Drosophila, the mutant black (b) has a black body and the wild-type (b+) has a gray body; the mutant vestigial (v) has wings that are short and crumpled compared the long wild-type wings (v+). These genes are linked and are located on the X- chromosome. A cross between a female fly and a black, vestigial winged male fly produced the following progeny: gray (b+), normal (v+) 20 gray (b+), vestigial (v) 120 black (b), normal (v+) 123 black (b) vestigial (v) 25 What is the map distance between the two genes? OA) 13.3 CM B) 15.6 CM 1 C) 84.4 CM OD) 18.5 CM E) 72.3 CM

Answer 1

= 20 GMay (6+) normal (v+) Gray (b) vestigial (v) = 120 black (6) Normal (V+) = 123 Black (6) vestigial) 25 Maß distance between two genes. = NUA Number of wrecombinant offspring X 100 Total number of offspring → 95 +20 x 100 120 + 123 +25 +20 45 X100 个 288 → 15.6 CM Highest number shows parental Parental type while lowest number Shows che combinant type

Obtión Bis is correct choice 3) mRNA messenger RNA carries the polypeptide Coding sequence for gene. 5) Both head and travel along the template a s' to 31 directions in DNA estrand of A correct
