Answer:the probability of their first two offspring being aa is 0.25
Explanation:
Because their are 4 possible genotypes for the offsprings
AA Aa Aa aa
And the probability of aa is 1/4
The standard plate count (SPC) method involves diluting 1.0m of bacterial culture into a series of water blanks, and then taking a sample from the water blanks to add to empty petri plates which will be filled with melted agar.
The standard plate count is a method used in microbiology, which is used to gain an insight to estimate the density of bacterial population which is present in a bacterial culture broth. This is done by plating a small concentration of the culture in a petri-dish and then counting the colonies which form in the petri-plate. This method is used mostly in the food industry, to find the density of mesophilic bacteria in food. This method is extremely essential to determine the primary source of the bacterial contaminant.

1. Distance from the Earth to the Sun
2. Hurt your hand from the reaction force (Newton's 3rd law is every action has an equal and opposite reaction)
3. The Earth to rotate slightly slower (I think)
Hope this helps :)
Answer:
The correct answer is - All offsprings are black-furred mice.
Explanation:
In this case, the parent mice are black and a cross between these mice produces offspring one allele from both parents. Here, black fur is dominant over white fur.
All the babies are with dark fur colors, no whites as black is a dominant color, so it produces black due to cross between two true breeds.
