Spondylosis is a term for age-related wear and tear of the spinal disks.
Answer:
F1 Generation -
Genotype - GgRr
Phenotype - Green and round
F2 generation -
Genotype Ratio –
GGRR: GGRr: GgRR: GgRr: GGrr: Ggrr: ggRR: ggRr: ggrr
1:2:2:4:1:2:1:2:1
Phenotypic ration
Green & round: Green & wrinkled: yellow & round:yellow : wrinkled
9: 3:3:1
Explanation:
G represents Green seed color
g represents yellow seed color
R represents round seed
r represents wrinkled seed
Here G is dominant over g and R is dominant over r
F1 generation -
Genotype of true breeding parents will be
GGRR and ggrr
The offspring produced will be -
GgRr
Genotype - GgRr
Phenotype - Green and round
F2 Generation -
Genotype Ratio –
GGRR: GGRr: GgRR: GgRr: GGrr: Ggrr: ggRR: ggRr: ggrr
1:2:2:4:1:2:1:2:1
Phenotypic ration
Green & round: Green & wrinkled: yellow & round:yellow : wrinkled
9: 3:3:1
B) Endocrine disruptors mimic hormones that regulate critical biological processes
Answer:
The right answer to this question is option A) island forms and mainland forms descended from common ancestors.
It's known in science that a long time ago, all the continents were only one, united all together in a bigger one. This can be observed by the way every continent can fit another one.
A proof of that too, is evolution, when we find organisms in an island that share some characteristics with organisms from another island, that can mean some things, they come from the same place, or these islands share characteristics that lead these organisms to be this way through evolution.
