A. Distinguish between the dominant and recessive traits. B. State two laws of heredity that were developed from Mendel's work. Be sure you can explain them. C. Explain the difference between a gene and an allele. D. Describe how Mendel's results can be explained by scientific knowledge of genes. E. Use a Punnett square to predict the results of monohybrid and dihybrid crosses. F. Differentiate between a monohybrid and dihybrid cross.

What must be true about the genotypes of parents who have a child who has an: a. dominant trait? b. recessive trait?

Mendel's Eggs Predict the Inheritance Patterns of the offspring by observing the parent's Egg color. dominant to Pink (p). Egg 1: Looking at Egg 1 the Parents are homozygous Purple (PP) and Pink (pp). Purple (P) is Before opening the egg, predict the color of their 4 offspring. Prediction : Actual Offspring: Number and color of predicted offspring: Egg 2: Looking at Egg 2 the Parents are heterozygous (Pp) and are both Blue (P)Blue, p green Before opening the egg, predict the color of their 4 offspring. Prediction : Actual Offspring: Number and color of predicted offspring:

This is simple mendelian trait A.name the phenotypes of the parents and write their genotypes B.determine the probabilities of the phenotype and genotype of Fi C.what are phenotypic ratios and genotypic ratios of F1

Gregor Mendel developed an understanding of heredity through his experiments with pea plants. The diagram below shows a cell with 2 pairs of homologous chromosomes and genotype of AaBb. a. Identify all the possible allele combinations that could be formed if this cell undergoes meiosis. b. Identify one of Mendel's laws that is illustrated when you write out these allele combinations. EXPLAIN this law.

When the phenotype of the offspring is determined by environmental effects only…   a. it is due to epistasis   b. it is a genotype-by-environment effect   c. it is maternal inheritance   d. a non-additive genetic effect   e. it has a narrow sense heritability of zero.

An individual may inherit three or more of eachtype of chromosome characteristic of the species, acondition called polyploidy.c. A female child inherits one X chromosome from hermother and one from her father.d. Pedigree analysis can be used to determine a futurechild’s chance of being born with achondroplasia
