CHROMOSOMAL SEX DETERMINATION

gonochorists have one sex chromosome called
1. heterochromosome (gonosome)
2. autosome
3. homological chromosome
The pair heterochromosome is called
1. X
2. Y
3. Z
The non-pair heterochromosome (so called alosome) is called
1. Y chromosome
2. X chromosome
3. Z chromosome
The pair of homological chromosomes by mammal females is
1. XX
2. XY
Non-geminate chromosomal pair by males
1. XY
2. XX
Eggs contain chromosome X
1. = homogametic sex
2. = heterogametic sex
The mammal type is also called
1. Drosophila type
2. Abraxas type
Drosophila type occurs by
1. dioecious plants, insects except for butterflies
2. monoecious plants, insects except for butterflies
3. dioecious plants, insects including butterflies
Bird type is also called
1. Abraxas type
2. Drosophila type
Abraxas type occurs by
1. birds and butterflies
2. all species of fishes, amphibians and reptiles
3. mammals
