Cleavage Division...... Hope it helps, Have a nice day :)
2. Answer: a. Resulting phenotypes: 100% Yellow.
b. No, there are not blue kernels.
c. All kernels are yellow because the yellow allele (Y) is
dominant over blue allele (y).
Explanation: Crosses a (YY x Yy) and b (YY x yy) result in yellow offspring with genotypes: 1) Dominant homozygote (YY) and 2) Heterozygous (Yy).
4. Answer: a. Genotypes: YY (25%) , Yy (50%) and yy (25%).
b. Phenotypes: Yellow (75%) and blue (25%).
c. There are more blue kernels in the F2 than in the F1.
Explanation: Crosses between F1 members (Yy x Yy) result in yellow and blue offspring with genotypes: 1) Dominant homozygote (YY, 25%) 2) Heterozygous (Yy, 50%) and 3) Recessive homozygote (yy, 25%).
5. Answer: a. Ys and YS
b. YS, yS, Ys, ys.
Explanation: The yellow and smooth individuals with genotype (YYSs) can produce two different gametes: Ys (Yellow and wrinkled) and YS (Yellow and smooth). The yellow and smooth individuals with genotype (YySs) can produce four different gametes: YS (yellow ans smooth), yS (Blue and smooth), Ys (Yellow and wrinkled) and ys (Blue and wrinkled).
Answer: As matter cycles and energy flows through living systems and between living systems and the physical environment, matter and energy are conserved in each change. The carbon cycle provides an example of matter cycling and energy flow in ecosystems.
