in the the dihybrid cross of Mendel how many genotype and phenotype?

What are result of dihybrid cross where the two parent different in two pair of constrastig traits?

Define monohybrid crosses?

Explain how linkage affects the outcome of crosses?

In rabbits, an allelic series helps determine coat color. The alleles, in order of dominance, are listed below. C=full coat color Cch-chinchilla Ch-himalayan c=white What is the predicted outcome for a CCh rabbit crossed with a Cchc rabbit? Draw out the cross and show the predicted genotypes and phenotypes for the offspring.

Explain why heterozygotes for inversions and translocations have low fertility.

Part 3: Use homologous chromosomes marked with alleles “A” and “a” and a second pair of homologs marked with alleles “B” and “b”. to demonstrate Mendel’s Principle of Independent Assortment in cells in Meiosis. Indicate what phase this happens in meiosis. Part 4: Use AaBb x AaBb and two Punnett squares to demonstrate Mendel’s Principle of Independent Assortment. Write the expected phenotypic ratios under each Punnett square. Now, multiply the probabilities of each event to get combined probabilities for BOTH genes. i.e. the chance of being homozygous recessive for both genes is 1/4 x 1/4 =1/16.

in humans brown eyes (B) are dominant over blue (b).A brown eye man marries a blue-eyed woman and they have three children , two of whom are brown eyed and one of whom is blue eyed.Draw the punnett square that illustrate this marrage.what is the man's genotype ? what are the genotype of the children?

When does Mendel’s first law occur of equal segregation occur? Does it occur during mitosis, meiosis I, and/or meiosis II?

What is the cross between the progeny of F1 and the homozygous reccessive parent called? How is it usefull?
