The following Mendel concluded about patterns of inheritance : C) Similar forms of genes account for variation in the inherited traits.
What did Mendel conclude about patterns of inheritance?Mendel concluded that inheritance is determined by discrete units called genes, which are passed down from parents to offspring in a predictable manner.
He observed that some traits are dominant over others, and that these dominant traits can mask the expression of recessive traits. Mendel also proposed the Law of Segregation, which states that during gamete formation, the two alleles of a gene separate from each other so that each gamete carries only one allele for each gene.

The trait for the type of leaf margin is con-
trolled by 1 pair of alleles. Serrate margin is
dominant over entire margin. Two plants
with serrate margin leaves (1 heterozygous
and 1 homozygous dominant) are crossed.
What is the chance that the offspring have
entire leaves
Since the genotype ss is the only one that produces the entire margin phenotype, the chance of an offspring having entire leaves is 50% (1 out of 2 possible genotypes: ss or Ss/sS).
What is an allele?An allele is a variant form of a gene that can determine a specific trait or characteristic. Genes are located on chromosomes and can have multiple alleles, which can be dominant, recessive, or codominant. Alleles can be inherited from both parents and can interact with other alleles to determine the phenotype of an organism. For example, the gene for eye color in humans has several alleles, including brown, blue, and green.
The offspring will have a 50% chance of having entire leaves.
When the heterozygous (Ss) and homozygous dominant (SS) plants are crossed, their offspring will inherit one allele from each parent. The possible combinations of alleles are: SS, Ss, and sS (which is the same as Ss).
The genotype SS and Ss both have the dominant allele for serrate margins, while the genotype ss has the recessive allele for entire margins.
Therefore, the possible genotypes and their corresponding phenotypes are:
SS: Serrate margin
Ss: Serrate margin
sS: Serrate margin
ss: Entire margin

What is the origin of the term cell in biology?
Answer:
The Origins Of The Word 'Cell' In the 1660s, Robert Hooke looked through a primitive microscope at a thinly cut piece of cork. He saw a series of walled boxes that reminded him of the tiny rooms, or cellula, occupied by monks. Medical historian Dr. Howard Markel discusses Hooke's coining of the word "cell."
