Hi!
The correct answer would be A.
<h3>Explanation:</h3>
As the allele P for polka dot is dominant to the allele p for solid color, it would yield a Polka dot tail in the individual in the presence of just one allele of P, while masking the effect of p for solid color.
So the possible genotypes and phenotypes would be as follows:
- PP (Polka dot tail)
- Pp (Polka dot tail)
- pP (Polka dot tail)
- pp (Solid color tail)
Following a cross by two heterozygous individuals, there would be 25 percent chance (1/4) of having the genotype pp , 25 percent (1/4) chance of having the genotype PP and 50 percent (2/4) chance of having the genotype Pp.
But the phenotype yielded by Pp and PP offspring would be polka dots, so there is a 75 percent (3/4) chance of having polka dot offspring, and 25 percent chance of having solid colored tail offspring.
<h3>Hope this helps!</h3>
Answer:
Well there are many abiotic elements, that the rest of the world shares. There is the warm soft breezes, the sun /sunlight, soil (for the decomposers), as mentioned above, there is lots of water, for the biotic features of the rainforest. Without these elements, most biotic (living) elements in the rainforest would die.
Explanation:
I think the correct answer would be the third option. Environmental influences include family dynamics, neighborhood quality, and educational opportunities. These influences involve everything that surrounds an individual. The environment one is subjected to greatly affects the totality of that person may it be psychological, social, physical, behavior or attitude, beliefs and perception. For instance, if a child grow up in an environment that is healthy where relationships are nurtured and love and respect is present between members, then most likely this child would grow with great self esteem and would have the same characteristics as the people he lived with.
This is incomplete dominance, you could use R for red W for white and RW for pink
