Answer:
The correct answer is -
The genotype of offspring - 1:2:1 (YY:Yy:yy)
The phenotype of offspring - 3:1 (dominant trait: recessive trait)
Explanation:
In this question, it is stated that there is a cross between Yy and Yy. By the genotype of the parents, we can say that Y is dominant for a particular trait and y is recessive and the parents are in the heterozygous condition in this cross. The gametes these parents will produce are - Y and y and Y and y
then the cross of Yy and Yy would be -
Y y
Y YY Yy
y Yy yy
Offspring from this cross are YY, Yy, Yy, and yy which means the genotypic ratio is - 1:2:1 and the phenotypic ratio is - 3:1 as three out of four are dominant.
Answer:
: Notice the rate of diffusion increases as the concentration gradient increases. If the concentration of molecules outside the cell is very high relative to the internal cell concentration, the rate of diffusion will also be high.
