Answer:
In translocation, a piece of chromosome or a whole chromosome breaks off during meiosis and attaches itself to another chromosome. The presence of an extra part of the number 21 chromosome causes the features of Down syndrome.
The correct answer is - b. The owl and the robin have more characteristics in common.
All three animals are in fact connected, but the connections are very different. While the owl and the robin are closely related, their connection with the bat can be traced few hundred million years ago. The owl and the robin are both birds, they share common ancestors in the early transitional species of bird-like dinosaurs, and before that their ancestors were part of the dinosaurs. The bat on the other hand, is a mammal, and has evolved from the primitive shrew like mammals that got an open space after the dinosaurs disappeared, and while living along side them were living in their shadow. So the bat's connection to the owl and the robin is going much further into the geologic past, before the diversification of the species to mammals and reptiles.
Answer:
The correct answer is - the phenotypic ratio would be 9:3:3:1.
Explanation:
The two traits that are dominant are free earlobe and straight thumb that are denoted by the E and T on their alternative recessive alleles attached lobe and hitchhiker thumbs denoted by the e and t respectively. The heterozygous condition will be EeTt.
The cross between EeTt and EeTt will produce gametes ET, Et, eT, and et by each. The phenotypic ratio of the cross would be 9:3:3:1, which means 9 out of 16 offspring will be dominant in both trait, 3 will be free lobe and hitchhiker thumb, 3 will be straight thumb and attached earlobe, and 1 will be recessive in both traits. For the cross please check the attached image.
Thus, the correct answer is - the phenotypic ratio would be 9:3:3:1.
