Problem 6 Short hair in rabbits is governed by a dominant gene (L) and long hair by its recessive allele (1). Black hair results from the action of the dominant genotype (B_) and brown hair from the recessive genotype (bb). a. Construct a Punnet square representing a cross between a dihybrid short, black, and homozygous short, brown rabbits. What genotypic and phenotypic ratios are expected among their progeny? b. Determine the expected genotypic and phenotypic ratios in progeny from the cross LLBB x Llbb. c. From crosses between LIBb and LIBB, c.l What is the expected phenotypic ratio among the progenies? c.2 What progeny of the Fi genotypes breed true (i.c., what percentage is of homozygous genotypes)? c.3 What percentage of the Fi genotypes is heterozygous for only one pair of genes? c.4 What percentage of the Fi genotypes is heterozygous at both loci?

Fungal Infections

Fungal infection can be defined as an infectious disease caused by fungi. A fungal infection is also referred to as mycosis. Fungal infections are contagious, spreading from person to person. Mycosis can be contracted even from an infected animal or contaminated soil. The most common symptom is skin rashes and vaginal discharge in females.
