Answer: The probability of having an offspring that is dwarf in size is zero.
Explanation: Since tall phenotype is dominant to dwarf phenotype, let T represent allele for tall and t represent allele for dwarf. A heterozygous pea plant will have Tt genotype while a homozygous tall pea plant will have a TT genotype. A cross between them will produce two homozygous tall pea plants (TT) and two heterozygous tall pea plant (Tt). They will not have any offspring having a dwarf size. Therefore, the probability of having a dwarf offspring is zero.

Answer:
The term “epigenetics” was introduced in 1942 by embryologist Conrad Waddington, who, relating it to the 17th century concept of “epigenesis”, defined it as the complex of developmental processes between the genotype and phenotype.
Explanation:
Answer:
Option D. Roots, stems, and leaves.
Explanation:
Ground tissue is a type of which are present in roots, stem, seed and leaves etc. Ground tissue is responsible for the production of food materials. These tissues also helps in the storage of food substance that are prepared in the leaves and gives support to the plant. Ground tissue is formed from parenchyma, collenchyma, and sclerenchyma.
C, Both types of organisms contain exactly the same four nitrogen bases, but in different sequences and numbers.
Answer:
c. 20 amino acids
Explanation:
There are 20 different amino acids that makeup proteins. The four-letter "alphabet" is referring to how DNA and RNA utilize ATCG and AUCG respectfully. DNA and RNA encode for amino acids that become proteins. Hope this helps :)
