In mice Y is the dominant allele for yellow fur and y is the recessive allele for grey fur. Since Y is lethal when homozygous, the result of cross `Yy xx Yy` will be

In Cucurbita, W is epistatic over Y and y gene normally responsible for yellow and green colour fruits. It produces white flowers. What is the ratio of fruits in the progeny of cross WwYy xx wwYy ?

If'A' respresent the dominant gane and 'a' represent its recessive alleles, what will be result of cross between Aa and aa

An organism has a gene ' X '. Its dominant allele expresses character c - 1 while it's recessive allele expresses character c - 2 This dominant allele is completely dominant over the recessive allele . It has another gene ' y ' which in its dominant form doesn't allow any expression of gene ' x ' which of these genotypes of that organism Will produce character c - 1 ?

In ant lions the gene for dull teeth is dominant D. The recessive gene d produces sharp teeth . Another gene T, when homozygous , produces dark-brown coats . Its allele t, when homozygous , produces albino coats. The heterozygote Tt is chocolate coloured . If a chocolate coloured , dull toothed male whose father was sharp toothed is mated to a chocolate , sharp -toothed female , what is the probability that an albino , sharp - toothed offspring will be produced ?
