Okay consider a cross of beetles with exoskeleton allies b and b and leg size alleles n and n. the male parent is heterozygous in both traits. the females parent is homozygous recessive in both traits

Answer

This cross will generate puppies with the genotypes of 25% BbNN, 25% Bbnn, 25% bbNn and 25% bbnn.

Explanation:

In this case the parent beetle has genotype BbNn and the mother beetle is bbnn. To solve this intersection, we have to remember Mendel's law of independent segregation and perform the traits intersections separately and multiply the percentages later.

1 - Characteristic of the exoskeleton: Bb x bb that gives us 50% Bb, 50% bb.

2 - Leg feature: Nn vs nn which gives us 50% Nn and 50% nn as well.

Finally, that means the cross of beetles have a chance to origin puppies with (0,5 * 0,5) in each different trait, resulting in the genotypes of 25% BbNN, 25% Bbnn, 25% bbNn and 25% bbnn

the answer is yes, they are born/created, then they grow to their limit then produce offspring, then die.

a adaptation is when organism changes itself to fit the environment

ex. when its cold outside i wear a jacket

hello everyone my name is nevaeh, i know everyone needs in some way, shape, or form and i am willing to provide. i set up a google classroom where people can ask me questions and get on work. no question is a stupid question so do not be afraid to ask. i usually only focus on core subjects but if you ask i will with other specialized subjects. i can do essays all the way to power points : )

my google classroom is the code is 7hr2k4

~ use this opportunity to get more so you can thrive in the classroom
