- Animals exhibiting external fertilisation produce a large number of gametes. Pick the appropriate reason from the following. (a) The animals are small in size and want to produce more offsprings. (b) Food is available in plenty in water. (c) To ensure better chance of fertilisation. (d) Water promotes production of large number of gametes.The purple sea urchin (Strongylocentrotus purpuratus) and a sympatric species known as the red sea urchin (Strongylocentrotus franciscanus) release their gametes into the Pacific Ocean at the same time, but the sperm cells of each species fail to fertilize the egg cells of the other species due to different membrane proteins. This prevention of interspecific fertilization in sea urchins is: a post-zygotic barrier known as F1 hybrid inviability a pre-zygotic barrier known as habitat isolation a post-zygotic barrier known as F1 hybrid sterility a pre-zygotic barrier known as gamete isolation a pre-zygotic barrier known as temporal isolationCalico cats are almost invariably female. Why? (Hint: explain genotype and phenotype of calico females)

He admired how quickly she moved using her powerful legs. She, in turn, was drawn to his skill as a sword fighter, using his tail ( for which she is homozygous) to slither about quietly with his weapon.

- Question: Placental mammals are characterized by their ability to lay eggs. True or False?d) The graph in Figure 2 shows the effect of light on the period of oestrus in two groups of female sheep. The females in the control group were subjected to the normal seasonal variation in day length. Partially through the first year of the experiment, sheep in the experimental group were subjected to reversed day-length cycle. The period of oestrus of each group of sheep is shown in solid bands above the graph (Figure 2). Control Periods of oestrus Experimental 20- Experimental 18- 16- 14- 12- 10- 8- 6- Control Jun Aug Oct Dec Feb Apr Jun Aug Oct Dec Feb Month FIGURE 2 Using information from the graph in Figure 2, answer the following questions: During what months does oestrus occur in each group? Give ONE advantage of this pattern of oestrus to the sheep in the control group. Explain your answer. What information can be deduced from this experiment. Length of daylight/hours7. Maternal effect: In Limnaea snail cats, R makes right coiled shells; r makes left coiled shells, and R is dominant to r, as we discussed in class. Even though these can be hermaphrodites, and act either as mom or dad, we'll just pretend they are male or female. A Rr male marries an rr female. a) What are the genotypes of their offspring and in what ratio? b) What are the phenotypes of their offspring and in what ratio?
- In general, mammalian sperm are viable even if they are aneuploid, but pollen grains (a.k.a. “plant sperm”) are not. Why?Male parental care occurs in only 7% of fishes and amphibianspecies with internal fertilization but in 69% of species with externalfertilization. Propose an explanation for why this is so.3) In the human brain, an estimated average rate of 250,000 nerve cells are produced each minute during gestation and through 6 months after birth. a) How many nerve cells are in a healthy 6-month-old human brain? i) 1.62 x 10³ nerve cells ii) 1.62 x 10¹¹ nerve cells iii) 1.62 x 10¹4 nerve cells egg is 4) One of the earliest stages of fertilization that can be measured in a sea urchin depolarization of the membrane around the egg. This occurs in 2 seconds. Egg and sperm nuclei fuse at around 1200 seconds and the first division of the zygote is at 5500 seconds. a) How many times longer does the process of nuclear fusion take than membrane depolarization? i) 2 times ii) 100 times iii) 600 times iv) 1200 times b) What is the maximum amount of time needed to synthesize a complete set of chromosomes in the sea urchin zygote prior to its first division? i) 2 seconds seconds ii) 1198 seconds iii) 1200 seconds iv) 4300 seconds v) 5500
