The regression coefficient represents the slope of the regression line. •b = 1 When the regression coefficient is 1, a 1-unit increase in x is associated with a 1-unit increase in y. У b = 0.4 When the regression b = 0.2 coefficient is 0.2, a 1-unit increase in x is associated with a 0.2-unit increase in y. 24.14 The regression coefficient, b, represents the change in y per unit change in x. Shown here are regression lines with different regression coefficients.

Which of the following statements is true about the molecular basis of Mendel's second law? OThe random attachment of the sister chromatids and the split of them into different daughter cells during the second round of cell division in Meiosis ensure Mendel's second law of independent assortment of alleles. OThe random attachment of the sister chromatids and the split of them into different daughter cells during the first round of cell division in Meiosis ensure Mendel's 2nd law. O The molecular basis of independent assortment of alleles is the segregation of sister chromatids during the second round of cell division in Meiosis. O The molecular basis of independent assortment of alleles is the segregation of homologous chromosomes during the second round of cell division in Meiosis. O The molecular basis of independent assortment of alleles is the segregation of homologous chromosomes during the first round of cell division in Meiosis.

If the tobacco plant parents are both heterozygous for color, what are the possible genotypes and phenotypes of their offspring? Complete the Punnett square below. What is the expected phenotypic ratio?

Suppose two parents, a father with the genotype AaBbccDd and a mother with the genotype aaBbCcDd, want to have children. Assume the loci are inherited independently of each other. Enter your answers as the most simplified fractions (e.g. 1/8 instead of 2/16). What proportion of the offspring are expected to have: The same genotype as the father?  The same phenotype as the father?  All dominant phenotypes?  All recessive phenotypes?

A cross is performed between individuals with the following genotypes: Aabb and aaBb. Use a Punnett square and predicted probabilities to answer the following questions. A. What is the probability that an offspring is dominant for the first trait and recessive for the second?  B. What is the probability that an offspring is dominant for both traits?  C. What is the probability that two offspring are dominant for both traits?

Round (R) and yellow (Y) are dominant over wrinkled (r) and green (y) peas. Given the case that parent plant 1 is homozygous for the round pea trait and heterozygous for the yellow trait, and parent plant 2 is heterozygous for the round trait and is green, answer the following questions 1. The genotype for parent plant 1 is and the genotype for parent plant 2 is 2. The percentage of offspring with green peas is 3. The percentage of offspring with wrinkled peas is % 4. The offspring would most likely show the phenotypes of shaped peas and coloured peas.
