Bacteria are classified into 5 groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes). They can exist as single cells, in pairs, chains or clusters.
Food moves through the digestive system tract by peristalsis, which is produced by wavelike contractions of INVOLUNTARY muscles
She should conduct an expirement that proves whether the water changes the white flower or not
Answer:
The probability of getting a mottled offspring is 0%. There is no A2 allele involved in the cross.
Explanation:
<u>Available data</u>:
- The gene for petal color in a flower has incomplete dominance
- Two A1 alleles (A1A1) express black color
- Two A2 alleles (A2A2) express white color
- One of each allele (A1A2) express mottled color
In a cross between two black flowers, there is no allele A2, there are just two alleles A1. So, the cross is:
Parental) A1A1 x A1A1
Gametes) A1 A1 A1 A1
Punnet Square) A1 A1
A1 A1A1 A1A1
A1 A1A1 A1A1
F1 Phenotypes: 100% black flowers
F1 Genotype: 100% A1A1
There are 0% of probabilities of getting a mottled offspring.
