No Some scientists compared fossils of the common ancestor of horses with
modern horses. The table shows what the scientists found during their
analysis,

The scientists claim that modern horses are better adapted for survival in
the present-day environment than the common ancestor would have
been, Which two statements best support this claim?
A. Organisms that have hooves are more likely to reproduce.
B, Organisms with multiple toes are easily seen by predators, so parents choose
not to pass the trait on to their offspring,
c. Organisms with four legs will develop a hoof because of the need to balance
on four legs.
D. Organisms will acquire helpful traits from their surroundings to survive.
E. Organisms that have hooves are able to live in a variety of habitats.

Depending on the organism the number of in a cell may change

Considering the yellow and green pea color phenotypes studied by gregor mendel: a. what is the biochemical function of the protein that is specified by the gene responsible for the pea color phenotype? (1 point) b. a null allele of a gene is an allele that does not specify (or encode) any of the biochemical function that the gene normally provides (in other words, either no protein at all or only non-functional protein is produced from it). of the two alleles, y and y, which is more likely to be a null allele? (1 point) c. in terms of the underlying biochemistry, why is the y allele dominant to the y allele? (2 points) d. why are peas that are yy homozygotes green? (1 point) e. the amount of protein produced from a gene is roughly proportional to the number of functional copies of the gene carried by a cell or individual. what do the phenotypes of yy homozygotes, yy heterozygotes, and yy homozygotes tell us about the amount of sgr enzyme needed to produce a yellow color? explain your reasoning.
