the correct answer is DNA fingerprinting.
The DNA fingerprint, produced by digestion of both sets of DNA by restriction enzymes, is run on an electrophoresis gel, stained, and photographed. The patterns are then compared.
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:
<u>lysosomes</u>
Explanation:
They are spherical sac-like organelles that contain lytic enzymes that destroy aged and unwanted cells. They contain hydrolytic enzymes that destroy GM2, gangliosides a class of glycosphingolipid that are produced by the nerve cells. Mutations in the HEXA gene that leads to the translation of hexosaminidase A causes the genetic abnormality, Tay-Sachs.
