How did Mendel use self-pollination and cross-pollination techniques in his experiments with flower color to observe the basic patterns of inheritance?

By cross-pollinating a parental generation of plants with different colored flowers and allowing the F1 generation to self-pollinate, Mendel observed the basic patterns of inheritance in the F2 generation.

What can be concluded from Gregor Mendel's experiments with pea plants?

A heterozygous phenotype is the same as a homozygous dominant phenotype AND Allelic combinations for different genes may differ between parents and their offspring

Komodo dragons are sexually reproducing lizards with separate male and female individuals. Sex is determined by the ZW system. Males have two copies of the same type of sex chromosome, and females have sex chromosomes of different sizes that contain different genes. Select the term that describes the organization of the sexual organs in the Komodo dragon.

dioecious

Miniature wings, Xm, in Drosophila melanogaster result from an X-linked allele that is recessive to the allele for long wings, X+. Match the genotypes for each parent in the crosses below.

Male Parent Genotype: X+Y, XmY, XmY, X+Y, X+Y Female parent genotype: X+Xm, X+X+, X+Xm, XmXm, X+X+

Phenylketonuria (PKU) is a disease that results from a recessive gene. Two normal parents produce a child with PKU. What is the probability that a sperm from the father will contain the PKU allele? What is the probability that an egg from the mother will contain the PKU allele? What is the probability that their next child will have PKU? What is the probability that their next child will be heterozygous for the PKU gene?

The probability that a sperm from the father will contain the PKU allele... 1/2 The probability that an egg from the mother will contain the PKU allele... 1/2 The probability that their next child will have PKU... 1/4 The probability that their next child will be heterozygous for the PKU gene... 1/2 (Refer back to notes)
