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.
The intermediate disturbance hypothesis predicts that communities with intermediate levels of disturbance will have the most diversity. If disturbances become too rare, competitive dominants will eliminate other species, reducing diversity as equilibrium conditions develop.
The intermediate disturbance hypothesis predicts that the highest levels of diversity will occur at moderate disturbance levels. We investigated the species diversity, abundance, and species diversity of bacteria on the human body in relation to washing disturbance. According to IDH theory, diversity is maximized at intermediate levels of disturbance because species that thrive at both early and late successional stages can coexist. The intermediate disturbance hypothesis (IDH) proposes that when ecological disturbance is neither too rare nor too frequent, local species diversity is maximized.
