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: The correct answer is b. Syphilis.
Syphilis is a type of sexually transmitted disease and the causative agent is bacteria called Treponema pallidum. There are four stages of syphilis: primary, secondary, latent and tertiary. It is a highly contagious disease.
The disease starts to get spread from sores and the pregnant women can pass the disease to the child and can cause abnormalities or even death of the child. If syphilis is untreated till the tertiary phase, it can lead to problems in heart, blindness, deafness, brain, nerves leading to paralysis and even death.
Answer:
B.
Explanation: Hope this helps! ^^
Survival of White Rabbits occurs higher as compared to the Survival of Brown Rabbits due to camouflage abilities in that light colored environment.
<h3>Why resources are important for organism?</h3>
If there are not enough resources to support the individuals in a species, then they are unable to increase their population because resources helps in the growth and survival of a species.
Sharp teeth, rough skin, or claws to fight of predators are the adaptations that could affect an individual’s chance of survival because these adaptations prevent them from killing.
So we can conclude that Survival of White Rabbits occurs higher as compared to the Survival of Brown Rabbits due to camouflage abilities in that light colored environment.
