Answer:
D&B
Explanation:
Each chromosome contains a single double-stranded piece of DNA
one chromosome contains thousands of genes
<span>The law of segregation is a principle of Mendelian genetics. The law of segregation occurs during meiosis when gametes are formed. At this time, the alleles for each gene segregate from one another. As a result, each gamete contains only one allele per gene. Thus, the gametes are haploid. The gametes need to be haploid so the specie’s diploid number is maintained when the egg and sperm unite. As a result of the law of segregation, each diploid parent passes a random allele for each trait to his/her offspring during fertilization. Thus, segregation increases variation within a species.</span>
Answer:
Explanation:
Put one pair of letters across the top, the other pair of letters along the left side. Fill in the boxes using the letter above the top and the letter to the side.
Of the four total boxes, there are:
- two Hh
- two hh
50% Hh and 50% hh
Since the parent with hh is recessive, it's the plant with shorter height genes.
Recessive genes (h) are also not dominant. When paired with, a non-recessive letter, the offspring will have the non-recessive letter.
In this case, Hh plants will take the H, taller height.
The hh plants will take the "h", recessive, shorter height, because there is no other letter.
Therefore, 50% of the offspring will be regular height and 50% of the offspring will be shorter height.
Option c. They have two germ layers (diploblastic)
