In a human karyotype, chromosomes are arranged in 23 pairs. if we choose one of these pairs, such as pair 14, which of the following do the two chromosomes of the pair have in common?
a) length, centromere position, staining pattern, and dna sequences.
b) length, centromere position, and staining pattern only.
c) length and position of the centromere only.
d) they have nothing in common except they are x-shaped.
e) length, centromere position, staining pattern, and traits coded for by their genes.

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.
