Answer:
1. Polygenic
2. RW
Explanation:
1. A polygenic trait is regulated by more than one gene. The phenotype of the organism is regulated by sum total of all the dominant alleles of these genes. Therefore, these traits exhibit continuous variations and are called quantitative traits. Skin color in humans is an example as it is regulated by more than one genes and the phenotype is determined by total dominant alleles of these genes.
2. If allele R gives red phenotype and the W gives white phenotype, a cross between RR (red) and WW (white) would produce all the cows with RW genotype. The parent cow with RR genotype would form all the gametes with R allele while all the gametes from WW parent would have one copy of the W allele. The random fusion of gametes with R and W alleles would produce progeny with RW genotype.
The man whose ideas most closely resemble the sentence would be Lyell - geological processes would take millions of years.
The reason is that neither of the other people in this case - Malthus, Lamarck or Hutton would be heard saying any of the mentioned things and only Lyell would be the man whose ideas were here the ones who are also true.
To perform a testcross, scientists cross an organism with an unknown genotype with a homozygous recessive organism.
