Question details

Question 7-8: You have taken up a fascinating summer project studying the genetics of the diploid organism Helix pomatia, the common land snail. In H.pomatia, the dominant shell color is brown and the dominant antennae phenotype is long. Shell color is controlled by the B gene and antennae size is controlled by the L gene. The B and L gene are unlinked The recessive phenotypes for these two traits are white shells and short D Question 7 1 pts 1 pt] Question 7: When a brown shell, short antennae male snail is crossed to a white shell, long antennae female snail, the following F1 phenotypes were observed 43 brown shell, long antennae females 39 brown shell, long antennae males If the parents are true-breeding. what are the parent and progeny genotypes based only on the female F1: B/b: LN female F1:B/b:L female F1: B/b:L female F1: Bb ; O P: B/B:VI male x b/b:L/L female F1: B/b: L female F1: B/b:L female F1: B/b:L

[2 pts] Question 8: In snails, females are the homogametic sex (XX) and males are the heterogametic sex (XY). If the reciprocal cross is done from that described in questions 7 and now a white shell, long antennae male is crossed to a brown shell, short antennae female, the following F1 are observed: 52 brown shel, long antennae females 48 brown shell, short antennae males Which of the following are the correct genotypes of the F1 progeny of the reciprocal cross described in this question (question 8)? To earn full credit you must correctly select ALL that are possible
