The statement above is TRUE. Food handlers are expected to keep their nails short and trimmed; this is because the microbes under nails can be a great hazard to the food that is been prepared. Food handlers are not expected to wear nail polish or put on artificial finger nails and if they do, they must put on single use gloves.
The answer is 16. To calculate the range of a set of measurements you are calculating the difference between the highest number and the lowest number. So in this set of measurements the highest number is 31 and the lowest number is 11. To find the difference between numbers, you have to subtract them. If we subtract 11 from 31 we get 20. So, with that being said the range of the following set of measurements is 20.
Answer: The expected phenotypic ratio is- 9:3:3:1 ( that represents 9 Black hair and polled horns: 3 black hair with horns: 3 red hair and polled horns: 1 red hair with horns).
Explanation-
According to the information given in the question, in Holstein cattle the allele for black hair color (B) is dominant over the allele for red hair (b) whereas the allele for polled (P), or lacking horns, is dominant for the allele for having horns (p). As we know that, dominant allele ( depicted by capital letter such as B and P here) masks the expression of recessive allele ( depicted by small letter such as b and p here).
When parents with genotypes- BbPp ( Black hair and polled horns) are cross bred and alleles separate independently, they will produce 4 different phenotypes in the ratio - 9 Black hair and polled horns: 3 black hair with horns: 3 red hair and polled horns: 1 red hair with horns.
The genotypes produced by each parent are- BP, Bp, bP, and bp
