75% of the children will have the probability of being tasters. 25% will have the probability of being non- tasters.

Answer b)

There will be a 75% chance that their first child or their fourth child will be a taster.

The chances for every child will be the same because alleles assort independently during the time of gamete formation. Hence, the probability remains the same every time.

Answer c)

There will be a 25% chance for the first three offsprings to be non-tasters. 75% chances will be of them being tasters.

This is because the alleles assort independently each time during gamete formation. Hence, the chances will be the same every time.

Suppose the rate of plant growth on isle royale supports an equilibrium moose population of 850 moose in this scenario there are
lesya692 [45]

The population of moose will still be around 850 in 30 years.

<h3>What is carring capacity?</h3>

Carrying capacity is the number of individuals that an environment can support without significant negative impacts to the organism and its environment.

With that being said, the moose population size will be same or still 850 after 30 years. Rate of plant growth on isle Royale supported in equilibrium moose population of 850 moose and if there will more 200 mooses arrived then there will be no sufficient plants available to feed those additional mooses. This is the concept of carrying capacity. Carrying capacity is defined as the species average population size in particular habitat. Species population size is restricted by environmental factor like food, shelter, etc. If number of mooses will be increased in particular habitat and plants are limited ,then there will be strong competition between them, which results in survival of the fittest.

So when population size increases on Isle Royale,may be in beginning, for a while there will be sufficient plants to feed those additional 200 mooses, but after some time plant population will reduce and there will be not enough plants to feed all of the mooses. And if needs are not met, population will decreases which allows plants to grow in normal population to feed 850 mooses. So, after 30 years moose population size would be around 850 mooses.

A white flower with a homozygous recessive genotype for petal color would have a
Reptile [31]

Answer:

B. rr

Explanation:

Genotype- Is the genetic makeup of an organism.

An homozygous individual is one who has similar allele e.g AA

It could either be in dominant form(AA) or recessive form(aa)

An heterozygote individual has two different allele in its genotype e.g Aa

A dominant gene is a gene that expresses itself in the phenotype of an individual while a recessive gene is a gene that is not expressed in the phenotype.

The genotype for a white homozygous flower is WW while the genotype for homozygous recessive is ww.

The dominant genotype is usually denoted with capital letter and the recessive is denoted with small letter.
