I am not exactly sure but I would gn with protein because DNA does not look like that is how the cell is so maybe protein or starch
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.
