Answer:
- 4 out of 16 guinea pigs would have white hair.
- 12 out of 16 guinea pigs would have short hair.
Explanation:
This question involves two genes. One coding for hair color and the other for hair length in guinea pigs. The alleles for black and white hair are B and b respectively while the alleles for short and long hair are S and s respectively.
Based on this question, two parents that are heterozygous for both genes (BbSs) are crossed (as seen in the attached punnet square). The guinea pigs that have an allelic pair of bb have white hair while those that have an allelic pair of SS or Ss have short hair as described in this question.
Using the punnet square attached,
- 4 out of 16 guinea pigs would have white hair because 4 offsprings possess the genotype bb for the first gene.
- 12 out of 16 guinea pigs would have short hair because 12 offsprings possess the genotype SS or Ss for the second gene.
A usual heart rate in case of adults varies from 60 to 100 beats per minute. Usually, a lower heart rate at rest signifies more effective functioning of heart and better cardiovascular fitness. For example, a well-trained athlete may possess a usual resting heart rate closer to 40 beats in a minute.
The following is the correct order to measure the heart rate:
1. Make a fist.
2. Find a radial artery.
3. Feel a pulse.
4. Count for 10 seconds.
5. Multiply by 6.
Answer:
Type X Charcot-Marie-Tooth disease (CMTX) is caused by mutations in genes on the X chromosome, one of the two sex chromosomes. Within the various types of Charcot-Marie-Tooth disease, subtypes (such as CMT1A, CMT1B, CMT2A, CMT4A, and CMTX1) indicate different genetic causes.
Explanation:
Lard is the least healthy source of lipids based on the data in the table given in the question. The correct option among all the options that are given in the question is the second option.
