Answer:
The correct option is <em>B. 25 %</em>
Explanation:
A heterozygous type can be described as the type in which both the alleles of a gene are different. If both the alleles of a gene are similar in an organism, then the person is said to be homozygous for the trait.
In the above question, two heterozygous parents are to be cross- bred to check the probability of them producing homozygous alleles (AA).
A punnet square made will show the following results:
A O
A AA AO
B BA BO
Hence, there will be 25% chance that the offspring produced could be homozygous AA.
I think it is because the cold air is more dense than the hot air so the less dense air which is the warm air rises
<span>1. Heterozygous black rabbit will have genotype Bb</span>
2. If a heterozygous black rabbit and a brown rabbit were crossed:
<span>Bb x bb</span>
The offspring will be:
Bb Bb bb bb
Which means that half of them will be black and half brown (50%).
Because they use to be connected all the land use to be it was call Pangea or something like but we split bc of the plants moving

Answer:
Here's an example
Explanation:
Imprinting allows baby birds to understand appropriate behaviors and vocalizations for their species, and also helps birds to visually identify with other members of their species so they may choose appropriate mates later in life.
