Patrick and his partner Patricia recently had Lil’ Patty and Patricia is worried that the hospital made a mistake and mixed her baby with some other starfishes’. Lil’ Patty has a short head! Patrick is homozygous for his tall head and Patricia is heterozygous for her tall head. Create a Punnett square using T for the dominant gene and t for the recessive one.

As justin travels by train up a mountain, he observes that the terrain changes from coniferous trees to small shrubs. Which level of organization has most likely remained constant?

Why was it important that the catalase and the hydrogen peroxide were both at the required temperature before the catalase was added?

Why there was no oxygen released when the experiments were repeated with different enzymes?

In tertiary structure, the hydrophobic amino acids tend to be:

A. Tucked away inside the protein.
B. Exposed on the outside of the protein.
C. Distributed randomly throughout the protein
D. All above

I have a question about housekeeping genes? What is there effect on a cell if they are expressed at a higher level

Heterochromia iridium is a recessive autosomal condition in hurnons in which the colour of the iris of one eye is different from the colour of the other eye. Consider that in a human population, in a survey of 5000 people, two people were found to have heterochromia. Also, consider that the population is at Hardy-Weinberg equilibrium at this locus. Based on this information, answer the question:
(a) Assume that mating occurs at random with respect to this character. What frequency of the matings in this population will be between heterozygous individuals and homozygous dominant individuals?

Without a bioinformatics tool, how can you calculate the molecular weight of protein?

Human ABO blood groups are controlled by a single gene with three alleles IA, IB, and i. The three alleles contribute to four blood group phenotypes. In addition to the ABO blood groups, there are two other loci that control blood phenotypes, the MN blood group locus and the Rh factor locus. The MN blood group has two codominant alleles, LM and LN. The Rh factor locus also has two alleles, Rh+ and Rh-, where Rh+ is dominant. The two phenotypes at the Rh factor locus are Rh+ and Rh-

Suppose in a population, the frequency of the ABO allele IA is 0.36, and the 1 allele frequency is 0.26. In the same population, the frequency of the LM allele is 0.47, and the frequency of the Rh+ is 0.62.

What is the frequency of the genotype IB i LM LN Rh+ Rh+ if the population is in Hardy-Weinberg equilibrium?

What is the importance of taxonomy in biological studies? Describe any two cytological approaches that enable us to meet the objectives of taxonomy.
