Answer:
Skin color, Silver (S) is dominant over gold (s) is recessive. This inheritance pattern is normal dominance
Eye color, green (G) is dominant over blue (g) is recessive. This inheritance pattern is normal dominance
Hair color is inherited by incomplete dominance. Red (RR), White (rr) and striped (Rr).

1. Four eye-color variants in Drosophila- brown, carnation, apricot, and purple - are inherited as recessive traits. Red is the dominant wild-type color. Eight crosses are made between parents of pure-breeding lines. Which of these traits are inherited as X-linked and which are autosomal? Explain how you distinguish between X-inked and autosomal inheritance. a. b. Predict the F2 ratios of crosses between the F1 progeny in A, B, D, and G Cross Parents F1 Progeny FemaleMale Red Red Red Red...

! Required information Fruit flies normally have red eyes. Seven different true-breeding strains of fly with white eyes have been identified (A-G). In each strain, the white eye trait is due to an autosomal recessive allele. It is possible all seven strains have mutations in the same gene. Alternatively, they may have mutations in different genes. To determine how many genes are involved in eye...

Experimental technique: Reciprocal crosses
1)When Gregor Mendel conducted his genetic experiments with pea plants, he observed that a trait’s inheritance pattern was the same regardless of whether the trait was inherited from the maternal or paternal parent. Mendel made these observations by carrying out reciprocal crosses: For example, he first crossed a female plant homozygous for yellow seeds with a male plant homozygous for green seeds and then crossed a female plant homozygous for green seeds with a male plant homozygous for yellow seeds.Unlike...

1.My wife has black color eyes, the dominant trait. All of her family and relatives have dark eyes too. I have light color eyes (blue), the recessive trait. We are hoping for a blue-eyed baby. What is the probability we will have a baby with blue eyes? What is the probability we will have a baby with dark eyes? 2. In humans, tongue rolling is a dominant trait, those with the recessive condition cannot roll their tongues. Bob can roll...
