output, forcing males to conversely share their reproductive output with the polyandrous female with the other members of the harem. In turn, males provide all the parental care for the clutch deposited onto the nest whether the clutch or individual offspring are “his.” This leaves all “good” thus reproductively successful descendants (Alcock 2010). A similar example is seen in Stephen Emlem’s (1998) work on polyandry in species the Wattled Jacana (Jacana jacana) one in which female jacanas…

When goat man and black cat had children the traits that are passed down to their children are: the horns, strong bones, and other dominant traits. Also, there will be some traits that the baby will inherit from black cat. Because of this, the baby will not look exactly like goat man. The baby might act like a superhero because of the traits it can inherit from goat man and black cat. The baby can be affected by what black cat or the mother eats. For example, if the baby's mom eats junk food all…

Matthew Ridgley Chapter 9 October 18th, 2015 The Evolution of Parental Care  Key to explaining the diversity in parental behavior lies with the cost-benefit approach.  Both sexes for songbirds when parenting often bring food to their helpless young offspring in a nest.  While female are so engaged, she may not be able to gather food freely and so she would grow as rapidly then she might otherwise, this is an especially damaging outcome for these species in which female fecundity increases…

ones to create the offspring. This lab requires great observational skills in order to observe how the parental generation’s genes affected the offspring’s fur color. In order to generate a hypothesis students…

most successful, Scissors was 2nd, Toothpick was 3rd, and Clothespin was 4th. At the end of the First Generation, Tweezers had 7 offspring, Scissors had 3, Toothpick had 3, and Clothespin had 1. At the end of the Second Generation, Tweezers had 13 offspring, Scissors had 7, Toothpick had 5, and Clothespin had 2. At the end of the Third Generation, Tweezers had 19 offspring, Scissors had 10, Toothpick had 8, and Clothespin had 3. As seen in Graph #2 Tweezers was the most successful yet again. But…

Traits by Offspring Follows Predictable Rules, 2013). All the offspring also have either fringed or non-fringed wings, this allows them to fly with much more ease. This characteristic may be more beneficial in comparison to another wing type such as slower curved wings, though they are longer they may present a disadvantage in the way the dragons are able to move as it may be more difficult to fold the wings, making it uncomfortable for dragon on their landing. In creating offspring there are…

Figure 5-2. We will then microinject a pronucleus of several mini-horta single celled embryos with the DNA construct containing our tissue specific promoter and ERT-Cre gene. These embryos can then be implanted into a pseudopregnant female, and offspring that express Cre, assuming the gene was properly integrated should be screened for the heterozygous expression of Cre via PCR. Our Cre models only have to be heterozygous because one copy of the gene that codes for Cre is enough to produce the…

relationships , 30.3% of off spring were considered problem bears separate from the conflict status of their mother. The father-offspring relationships, were 28.6% and considered problem bears separate from the conflict status of their father . There was not anything indicating that conflict behavior was linked to the sex of the bear. The results proved that offspring that were involved in conflict behavior was because their mothers were problem bears, but not their fathers. It supported that…

get cystic fibrosis, the offspring must have received the mutated “CFTR” allele from both parents, meaning that they have 2 of the faulty alleles, which therefore causes cystic fibrosis. If only 1 of the mutated alleles is inherited by the offspring they do not have cystic fibrosis because they do not have 2 of the mutated CFTR alleles in order to cause cystic fibrosis, even though they do not get cystic fibrosis they will still be able to pass the allele onto their offspring, as their mutation…

identical offspring, humans produce sex cells, through the process of meiosis, that carry only half of the genetic information, and fertilize them in order to produce non-identical offspring (Science Learning Hub, 2011). The ability to create unique offspring for every –sexual reproduction- allow a greater chance of survival and mutations. Out of the 23 types of chromosome, the sex chromosome that determine…
