Today humans suffer more from orthodontic issues compared to ancient humans because of the change of food from hard foods to soft foods. This resulted to smaller faces and smaller jaws together with rounder and shorter cranial vault. This made the bones supporting the teeth reduce in size faster than the teeth resulting to crowding and malocclusions.

1/4 recessive can be expected for the recessive trait of mono hybrids from the F2 generation.

Option D

<h3><u>Explanation:</u></h3>

Mono hybrid cross is defined as the crossing between two plants considering the two different alleles of a particular character. It was 1st performed by Father of Genetics, Sir Gregor Mendel. The mono hybrid cross done by him considered the character tallness of garden pea plants, of which one was tall and other was short.

He crossed them to get all tall plants in 1^{st} Filial generation. Now as he self bred those plants, he got the tall and short plants in ratio of 3:1. Thus he proved that the recessive trait of mono hybrids is 1/4^{th} of the total population of F2 generation.

Do does anyone know this​
belka [17]

Answer:

I know that the "ATP" is in the mitochondria which we humans don't have so I would say the first one but I'm not sure but what I've read so far it might be or I'm not sure because u know how the Mitochondria is part of the power houses.

I would think it could also be F because the Mitochondria helps for Cellular respiration and also fermentation.

Explanation:

Therefore the correct answers: B,C, F

So the anwers I believe are with the ones that don't have the Photosynthesis because my explanation here is that animals also have their power houses lol that, that means it's the Mitochondria as well as the plants.

So mitochondria ATP captures energy in Cellular respiration.

Hope this helps u.. ;)

if a blue eyed offspring is formed from black eyes parents, what type of character is the blue eye dominant or recessive? expali
Alja [10]

Answer:

Blue Eyes Are: Recessive

Explanation:

The brown eye form of the eye colour gene (or allele) is dominant, whereas the blue eye allele is recessive. If both parents have brown eyes yet carry the allele for blue eyes, a quarter of the children will have blue eyes, and three quarters will have brown eyes. I hope this helps :) Good luck on your assignment!!!
