The next two questions go together.Suppose the tail length of two populations of lizards is controlled by one gene. To determine themode of inheritance, a true-breeding short-tailed female is crossed with a true-breeding long-tailedmale. Then, siblings from the F1 are crossed and the number of short- and long-tailed animals arecounted to determine the phenotype ratio.1. What phenotypic ratio do you expect in the F2 generation if tail length is controlled by anautosomal gene, and long tails are dominant to short tails?1 long: 1 shortmales 1 long: 1 short, females all shortO 3 long: 1 shortO 1 long: 3 short

Step 1

In genetics, the gene is the hereditary unit of life. A gene contains two alternative forms known as alleles. The allele which expresses itself is called the dominant allele and which gets suppressed is called recessive allele. When two similar alleles are present together it is called homozygous and when two dissimilar alleles are present, it is called heterozygous.

The dominant alleles can be present in homozygous as well as heterozygous form whereas recessive allele are present in homozygous form.

Phenotype is defined as the observable characteristics of a individual

Genotype is defined as the characteristics judged due to the genes of an individual.
