In prokaryotes DNA is located directly within the cellular cytoplasm
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:
Explanation: Tube 1 doesn't contain an organism so it can't be that one. Both a snail and a plant are considered an organism, and cellular respiration occurs in almost any organism's cells
