7. Consider the problem below. Cage 1 contains organisms caught in the wild. Other cages represent the results of a cross between the two parents indicated at the top of the cage. Cage 1 Cage 3 Parents- Organisms collected from the wild:- Leg Organisms Count Images Ô (Cage 1) Three-Leg x (Cage 1) Two-Leg Oooooooo Offspring 000000 Leg Organisms Count Images OOOO 0000 040 oooooooooooo 090 100 Three 040 TWO 10 Q Two Cage 7 Parents (Cage 1) Two-Leg X (Cage 1) Three-Leg Offspring- Leg Organisms Count Images Joooooooo 090 Three ջջջՋջՋջՋ 08 oooooooo9 080 O QQQQ 05 g Cage 5 Parents- Ô (Cage 1) Two-Leg x (Cage 1) Two-Leg Offspring Leg Organisms Count Images oooooooooooo 090 Two QQQQQQQQQQQQQ Two Which trait is dominant? (2points) Which cage made you confident of your answer above? (2points) What are the genotypes of the parents in each cage? (2points)

Answer 1

Two leg trait is dominant(L) and three leg is recessive(l).

Cage 3 made me confident. Because, homozygous recessive male(ll,three leg) crossed with homozygous dominant female(LL,two leg) produce heterozygous offspring (Ll,three leg).

Genotypes

Cage 3

recessive male(ll) X dominat female(LL)

Cage 7

Heterozygous male(Ll) X recessive female(ll)

Cage 5

Homozygous dominant (LL) male and female.
