What you should do in this case is to divide one large square in four smaller ones. Then on the line above the upper left square put the letters 'IA'. Next, on the line above the upper right square write the letter 'i'. In the same way, on the left side of the upper left square write the letters 'IB' and under it, left from the bottom left square write the letter 'i'. This gives you something like a table. In each of the blank squares you connect the corresponding letters together, from the upper and the left side to see the possible genotypes of the children.
Meaning, their genotypes would be: 25% IAIB, 25% IAi, 25% IBi, and 25% ii
Hope this helps :)
Well, if you mean their fur then it depends on their habitat location. They're usually a shade of brown but it can get very light or very dark...
If you mean the frills in their eyes then it's called Corpora Nigra and it's like sunglasses in their eyes and it basically helps shield their eyes from the sun so they won't have to squint or damage their eyes...especially since they live in warmer climates.
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
Answer:
1/2 or 50%
Explanation:
Given that the extra digit is a dominant trait, the man with an extra digit may be homozygous or heterozygous dominant for the trait.
However, having a daughter with his normal wife makes him heterozygous dominant. Let's assume that the genotype of the heterozygous dominant male is "Dd" and that of his wife is "dd".
The heterozygous dominant male and homozygous recessive female would have progeny in the following ratio= 1/2 Dd (child with extra digit): 1/2 dd (child with no extra digit).
