Answer:
Genetic variability refers to a species's genetic variation as a whole. Specific changes in DNA fragments or genes are referred to as genetic variants, and each mutation of a gene is referred to as an allele.

Answer:
The correct option is A. His research was not appreciated by the scientific community until after he died.
Explanation:
Gregor Mendel was an Austrian monk who laid the foundation of genetics. Mendel studies seven traits from the pea plants and formed the law of segregation and law of independent assortment.
The work of Mendel was not appreciated until his death. In the 20th century, his work was eventually rediscovered and appreciated.
However, Mendel's study did not include any explanations for polygenic traits. His results could predict heritability in both plants and animals.
Explanation:
<u>C. A red allele is present on both homologous chromosomes</u>
<u></u>
Homologous chromosomes are pairs of chromosome of similar lengths, banding patterns, and centromere positions, with genes at the same loci. For dominance, gene copies are present on both of the chromosomes; the dominat variant overrides the effect of the other recessive allele.
Further Explanation:
DNA molecules contain chromosomes that may have different forms called alleles. DNA, which is the genotype, is transcribed into mRNA and later translated into amino acids which are connected together by rRNA to form proteins which constitute the phenotype of an organism. DNA sequence mutations form new alleles, impacting the associated mRNA, and thus the encoded protein.
Homozygous individuals have a chromosome containing two variants of the same allele. Dominant homozygous individuals bear two copies of the dominant allele, whereas recessive homozygous individuals hold two copies of the recessive allele.
