The probability that one of the surviving kittens with parents having the allele M L M associated with taillessness in Manx cats will be heterozygous. Concept introduction: The mutated M L allele is associated with taillessness in Manx cats. The homozygous M L M L allele is called as lethal alleles, as they cause death of the kitten as embryo itself due to defects of the spinal cord. Lethal alleles are those in heterozygous or homozygous form that causes death of the individual during embryonic development itself. The probability reduces in such cases, as those alleles will not be transferred to the next generation as the allele is lost with the death of the embryo.

In giraffes, long neck is dominant to short neck. Long neck is denoted by the dominant allele, N, while short neck is denoted by a recessive allele, n. Write the genotype and phenotype for the following organisms: homozygous dominant organism, homozygous recessive organism, and heterozygous organism.

In fruit flies, the dominant H allele gives rise to a hairless phenotype, hh gives rise to normal body bristles, and the HH homozygote condition is lethal during an embryonic stage. The presence of a dominant S allele suppresses the effect of the dominat H allele with respect to the body bristles phenotype such that normal body bristle phenotype is restored when only one dominant H allele is present (HH is lethal irrespective of the S or s alleles). The ss genotype has no effect over the H allele and the SS homozygote condition is also lethal during an embryonic stage. What would be the expected phenotypic outcomes among the surviving offspring from the following cross: HhSs X hhSs 2 normal body bristles: 1 hairless 7 normal body bristles: 2 hairless 1 normal body bristles: 1 hairless 3 normal body bristles: 1 hairless 5 normal body bristles: 1 hairless

Identify each of the following as an example of allele, genotype, and/or phenotype frequency: A. Approximately 1 in 2500 people of Northern European descent is born with cystic fibrosis. B. The percentage of carriers of the sickle cell allele in West Africa is approximately 13%. C. The number of new mutations for achondroplasia, a genetic disorder, is approximately 5 × 10–5.
