When a plant with red flowers is crossed with a plant with white flowers, the F1 generation consists of a plant with pink flowers. This is an example of which of the following modes of inheritance? A. multiple alleles B. incomplete dominance C. codominance D. complete dominance

How do meiosis and gene expression explain the results from Crosses 1 and 2 OR from Crosses 3 and 4? Use evidence from the crosses to support your answer. You may also use the drawing tool to help explain or support your answer.

Consider a situation where you have a parental cross with the mother and father phenotypes listed below. Remember that the genotype for the wild-type parent is always homozygous.   The counts of the F1 offspring are listed in Table 1. Two randomly selected individuals are selected and mated to produce a set of F2 individuals. If you test the F2 counts to determine whether they are consistent with an autosomal dominant mode of inheritance, what is your decision? Use a 0.05 significance level.   PARENTAL CROSS   Parental cross: Mother with disease phenotype, Father with wild-type phenotype.   Table 1. F1 DATA   Gender Phenotype Disease Wild-type Male 0 23 Female 0 34         Table 2. F2 DATA   Gender Phenotype Disease Wild-type Male 7 25 Female 0 25     A)Do not reject the null hypothesis that the F2 data are consistent with an autosomal dominant mode of inheritance; chi-square goodness of fit test statistic value is between 0 and 1. B)Reject the null…

In horses, there are three coat colour patterns called cremello (beige/light brown), chestnut (brown) and palomino (golden with a light mane and tail). If two palomino horses are mated, they produce about % cremello, 4 chestnut and 2 palomino offspring. In contrast, cremello and chestnut horses breed true. Explain this pattern of inheritance. (Refer to the number of loci controlling the trait, the number of alleles per 3. a. locus and the dominance interaction between the alleles). b. Assign genotypes to the phenotypes.
