Most plants selected using this method will be retained as an improved variety in the case of self-pollinated crops or as a means of increasing the frequency of favorable genes in the case of cross-pollinated crops. This selection method can be performed using direct or indirect approaches.","questionTimeSeconds":"0","questionTimeMinutes":"1","questionImagePath":null,"position":null,"explanation":"","question_score_id":null,"lang":"","questionAudioPath":null},{"id":474662,"quiz_id":"24125","answer_id":null,"answerType_id":"0","created_at":"2018-05-24 21:24:03","updated_at":"2018-05-24 21:24:03","questionName":"Advantages of single seed descent include...","questionTimeSeconds":"0","questionTimeMinutes":"1","questionImagePath":null,"position":null,"explanation":"","question_score_id":null,"lang":"","questionAudioPath":null},{"id":474659,"quiz_id":"24125","answer_id":null,"answerType_id":"0","created_at":"2018-05-24 21:16:59","updated_at":"2018-05-24 21:16:59","questionName":"The purpose of ____________________ is to rapidly advance segregating populations through selfing to a suitable level of inbreeding prior to selection and evaluation.","questionTimeSeconds":"0","questionTimeMinutes":"1","questionImagePath":null,"position":null,"explanation":"","question_score_id":null,"lang":"","questionAudioPath":null},{"id":483118,"quiz_id":"24125","answer_id":null,"answerType_id":"1","created_at":"2018-06-04 19:30:28","updated_at":"2018-06-04 19:30:28","questionName":"_____________ are landmarks of a genome.","questionTimeSeconds":"0","questionTimeMinutes":"1","questionImagePath":null,"position":null,"explanation":"","question_score_id":null,"lang":"","questionAudioPath":null},{"id":474648,"quiz_id":"24125","answer_id":null,"answerType_id":"0","created_at":"2018-05-24 20:57:15","updated_at":"2018-05-24 20:57:15","questionName":"True or False: The bulk breeding method will not alter the proportion of genotypes in a population of mixed pure lines.","questionTimeSeconds":"0","questionTimeMinutes":"1","questionImagePath":null,"position":null,"explanation":"","question_score_id":null,"lang":"","questionAudioPath":null},{"id":474626,"quiz_id":"24125","answer_id":null,"answerType_id":"1","created_at":"2018-05-24 20:19:14","updated_at":"2018-05-24 20:19:14","questionName":"Indirect mass selection is practiced when heritability for a trait is ________ and the genetic correlation between two traits under selection is _______.","questionTimeSeconds":"0","questionTimeMinutes":"1","questionImagePath":null,"position":null,"explanation":"","question_score_id":null,"lang":"","questionAudioPath":null},{"id":474641,"quiz_id":"24125","answer_id":null,"answerType_id":"0","created_at":"2018-05-24 20:51:01","updated_at":"2018-05-24 20:51:01","questionName":"Which of the following statements are true regarding the bulk breeding method?","questionTimeSeconds":"0","questionTimeMinutes":"1","questionImagePath":null,"position":null,"explanation":"","question_score_id":null,"lang":"","questionAudioPath":null},{"id":479794,"quiz_id":"24125","answer_id":null,"answerType_id":"0","created_at":"2018-05-30 18:15:06","updated_at":"2018-05-30 18:15:06","questionName":"Which of the following are limitations to the use of recurrent selection in self-pollinated crops?","questionTimeSeconds":"0","questionTimeMinutes":"1","questionImagePath":null,"position":null,"explanation":"","question_score_id":null,"lang":"","questionAudioPath":null},{"id":474651,"quiz_id":"24125","answer_id":null,"answerType_id":"0","created_at":"2018-05-24 21:06:51","updated_at":"2018-05-24 21:06:51","questionName":"True or False: Individuals of a self-pollinated species within a bulk breeding program will continue to experience gain from selection each year that the bulk population is planted.","questionTimeSeconds":"0","questionTimeMinutes":"1","questionImagePath":null,"position":null,"explanation":"The individuals will not experience gain from selection after achieving homozygosity.

DNA Markers

Click and drag

A small region of DNA sequence showing polymorphism (deletion, insertion, and base substitution) in different individuals; detected by Southern blotting or PCR

Easily discernible traits with simple Mendelian inheritance; often have 1:1 correspondence with the genes controlling the traits.

Alternative forms of enzymes that often differ in electrophoretic mobility, but have the same enzyme activity. Detected on a starch gel.
