of offspring produced. Unlike other reptiles, alligators exhibit parental care; they nest-guard, and even offer evidence of maternal care for juveniles after hatching. Through the reviewing of multiple experiments conducted on Alligator mississippiensis, evidence is provided for the temperature-dependent mode of sexing and maternal

points are possible for this homework 1. A black guinea pig is crossed with an albino guinea pig, producing 12 black offspring. When the very same albino is crossed with another black guinea pig, 7 black and 5 albinos are obtained. Explain this genetic outcome by writing out the genotypes for the parents, gametes, and offspring in both crosses. First Cross: The fact that all F1 offspring are black suggests that the parents of the first cross were genotype BB x bb (where B=black and b=albino). The gametes

Maternal smoking during pregnancy (SDP) is associated with numerous adverse outcomes in offspring, such as cognitive problems (Batty et al. 2006; Gilman et al. 2008a, b) and criminal behavior (D’Onofrio et al. 2010a, b; Brennan et al. 2002; Wakschlag et al. 2002). These associations are often attributed to the causal effects of teratogenic insults on the developing offspring (for reviews, see Wakschlag et al. 2002; Cornelius and Day 2009). Several lines of evidence support this causal inference,

When the cells try to repairs the DNA might not get it right or because the cell end up with different code or DNA so it comes mutation. When our DNA the mutation it can pass to our offspring sexual reproduction are animals , plants . how sexual pass down to offspring or there

Cross B Analysis from Supplementary Gel: In cross B, a red-eyed female fly was placed into a vial with a white-eyed male fly and a red- eyed male fly for a breeding period of two weeks. At least eight red-eyed females were produced from this cross. These eight females were used to conduct a polymerase chain reaction. Comparing to the control groups, the results show that seven out of eight flies has the Xw+ Xw genotype because all of them had both bands appear on the gel when both alleles were present

Throughout the years scientists have considered birds to be monogamous species, mainly because majority of the animals that put in equal efforts(like birds) in rearing their offspring are. However recent advancement in genetic fingerprinting technology shows that a significant proportion of the offspring were conceived through Extra Pair Mating. Scientist still haven 't fully understood what factors lead to this behavior. However, with all the research done in this field there seems to be a relative

different pairs of color dot in the sexual experiment which produced different color dots than the original one. For example, the same 2 color dot can produce different color offspring, as the chart above, two lime produces 2 cream 4 lime and 2 brown. In Asexual chart, the color of parent can only reproduce 1 type of offspring, because they reproduce as single, and there is no diversity in each individual. Thus, Sexual reproduction has more diversity than Asexual reproduction. Asexual reproduce from

uncommon form of reproduction in the insect world, those that do have this type of reproduction fall into two main groups: those who have a high offspring rates and those who have low offspring rates. Viviparity, while uncommon, does serve a distinct purpose. In some cases the insect has very few ovarioles to begin with, in which case, it is essential for the offspring to be given the best chances at survival they can get. Having the embryo safely protected inside the insect while it develops gives the young

Selective breeding in animals is the process is which humans select certain animals to breed with each other in order for the offspring to have certain phenotypic traits. This also encompasses artificial embryo selection in which humans actively select embryos with have the genes for the phenotypic traits they desire in the offspring. Throughout history horses have been selectively bred to work for and with humans, beginning over 3000 years ago – before humans knew about genetic heritability. Many

Many survivors from the Holocaust are more likely to pass on genes containing stress disorders to their offspring. This is a very new idea and is being researched by New York’s Mount Sinai Hospital. The research team, led by Rachel Yehuda, reached this conclusion by conducting a genetic study of 32 Jewish men and women who were held in concentration camps, witnessed traumatic events, and were forced to hide in the Second World War. This idea is very controversial and is known as Epigenetic inheritance
