Mr. smith and his wife recently had a baby. mrs. smith has been upset since she first saw her new baby’s short eyelashes. she claims that the hospital goofed and mixed up her baby with someone else’s baby. having short eyelashes is a recessive trait and mr. smith is homozygous dominant for long eyelashes, while his wife is heterozygous. determine if the baby could be their child. a) create a punnett square using mr. and mrs. smith’s genotypes and calculate the probability of having a child who is homozygous recessive. b) using information from the punnett square, determine if the baby belongs to the smiths. in paragraph form, justify your response by providing supporting evidence and reasoning.

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.

If a baby girl guinea pig looks almost identical to its mother, does this then mean that it inherited more alleles from its mother? explain. (hint: think about the vocabulary words dominant and recessive.)
