Why are offspring of organisms that reproduce sexually not genetically identical to their parents
Nat2105 [25]

Answer:

The offspring of organisms that is reproduce through sexually are not genetically identical to their parents because the offspring contains genes from two parents.

Explanation:

Identical offspring is only formed when offspring is produced from one parent through asexual reproduction such as building, binary fission and fragmentation. In sexual reproduction, offspring is produced by the mating of two organisms i. e. male and female organism. That's why genes of offspring are different from their parents and offspring is not identical to parents.

What gametes are produced by the following organisms:_______.
vova2212 [387]

Answer:

The correct answer would be -

1- YR, Yr, yR and yr.

2. Yr, yR

3. YR, yr

4. YR, Yr, yR & yr

Explanation:

A mature male or female haploid germ cell that fuses with another gamete of the opposite sex during the process of fertilization to make a zygote in sexual reproduction.

The law of Independent Assortment presented by Mendel says that alleles for different traits are passed and assort independently of one another in the gametes.

1. If Y and R on different chromosomes then they will produce four gametes and assort independently - YR, Yr, yR & yr.

2) If Y and R on the same chromosomes and no crossing over occurs then they will produce only two gametes as Y and R will not come together - Yr & yR.

3).  if dominant Y and recessive r are on the same chromosome, no crossing over then only two gametes will form as Y and r will not assort together - YR & yr.

4). if dominant Y and R are on the same chromosome, 50% crossing over produces 4 types of gametes, YR, Yr, yR & yr.
